Added DiffLines:

** Another features a [[PompousPoliticalPundit blowhard radio pundit]], played by Creator/LewisBlack, who had a running feud with an actress who played a MsFanservice role on a TV show, and would often rant about how she's "asking to be raped." The episode's plot is kicked off when a teenage LoonyFan of the pundit actually goes and ''does'' it, prompting a huge debate about culpability and free speech among the characters. The episode ends with [[spoiler:the pundit being shot, albeit nonfatally, by the rapist's vengeful mother after the rapist is convicted]].

Added DiffLines:

** To a lesser extent, Shinra executive [[TokenGoodTeammate Reeve]] counts as well. He's the one who designed the Mako Reactors and the Mako refining process. If he had never made his discovery then Shinra wouldn't have risen to power, probably wouldn't have found Jenova, and the many world-ending events the planet experiences over the next two decades wouldn't have happened. He later becomes TheAtoner who tries to make up for the harm he did to the world by helping to build Shinra's power base.


** [[spoiler:Otome and Makoto]] might be even worse ones in some routes. It's depending on Makoto pulling one or another action that [[spoiler:Otome will or not tell Makoto's best friend Taisuke that girls like forceful dudes during sex -- which will lead him to rape his crush Kotonoha, under the very stupid belief that the poor girl's barely whispered "no, don't..." are actually a part of the "protest pretend" kink.

** [[spoiler:Otome and Makoto]] might be even worse ones in some routes. It's depending on Makoto pulling one or another action that [[spoiler:Otome will or not tell Makoto's best friend Taisuke that girls like forceful dudes during sex -- which will lead him to rape his crush Kotonoha, under the very stupid belief that the poor girl's barely whispered "no, don't..." are actually a part of the "protest pretend" kink. [[note]]where the passive partner in hentai/ecchi/hard yaoi/etc. medimedia fakes being embarrassment and unwillingness.[[/note]].]]
** Also, [[spoiler: Nanami, Hikari and Otome's GirlPosse]] can become the trope, when [[spoiler: they '''horribly''' bully Kotonoha to [[ShippingTorpedo keep her away from Makoto]] [[ShipperOnDeck and make sure Sekai gets him]].]] This can either lead to [[spoiler: Makoto ''completely cutting Sekai off his life'' before choosing Kotonoha since he thinks she's the one instigating the bullying that Koto has been a victim of [[note]](she's almost surely '''not''', but Makoto is simply too angry to consider that because school bullying is his BerserkButton)[[/note]] ]] or to [[spoiler: Kotonoha [[GoMadFromtheRevelation breaking down so badly]] for said harrassment that ''she murders Sekai in broad daylight''.]] In either way, their support to one girl over the other ''makes things MUCH worse for the one they wanted to "help"''.
* ''VisualNovel/UminekoWhenTheyCry'':
** [[spoiler:Battler Ushiromiya]] of all people, who drives [[spoiler:Sayo Yasuda]] to orchestrate the murders [[spoiler:by unwittingly breaking a promise to take them away from Rokkenjima]]. Battler didn't come back for it because of ''very'' serious family issues (depicted below), but unfortunately, [[spoiler:the already broken Sayo]] took this very, ''very'' badly.
** Furthermore, if that's the case, then [[spoiler: ''Rudolf and Kyrie'']] are also responsible. [[spoiler: Had they not [[ParentWithNewParamour married too soon after the death of Battler's beloved mother]] for the teenage Battler's taste, he would have not broken ties with his paternal family. Therefore, he would've showed up in Rokkenjima sooner and/or more frequently and, as the GuileHero he is, he would've found a way to help poor Sayo deal with their crappy situation, promise or not.]]
** There's also [[spoiler:Natsuhi]], who is largely responsible for [[spoiler:Sayo Yasuda]]'s issues in the first place. [[spoiler:Sayo was pretty much forcibly given to her by Kinzo as a baby to raise after she couldn't give birth to an heir, which [[GoodIsOldFashioned the very traditional Natsuhi]] saw as a reminder of her "failure" as a woman. One day, out of anger and resentment out of having to raise a child that wasn't her own, Natsuhi completely lost it and pushed a servant holding the baby off a cliff. The servant died but the baby survived, though with injuries that damaged their sexual organs, leading to Sayo having major gender/body issues later in life, which would ''not'' exactly help with their increasingly unstable mental state. An alternate continuity shows that, had Natsuhi not snapped the way she did, Sayo would grow into the [[TheAce far more stable]] [[AlternateSelf Lion Ushiromiya]].]]
* In ''VisualNovel/ZeroTimeDilemma'', Zero mentions a story of how a ''snail'' caused 6 deaths by just being where it was. A woman [[spoiler: heavily hinted to be Eric's mother]] used a different way than usual because a snail was on the usual one. This caused her to meet a young SerialKiller, [[spoiler: who turns out to be Mira]], and get killed. An innocent man [[spoiler: later revealed to be Akane's father]] was caught and sentenced to death, which lead to his wife to commit suicide. The man was going to catch a taxi but he couldn't, and the taxi driver took a surgeon going to operate a kid. The taxi had an accident and both the driver and the surgeon died. Since the kid never received his surgery, he died as well. [[ArcWords Life is simply unfair]]

[[folder:Web Animation]]
* In ''WebAnimation/DeathBattle'', [[WesternAnimation/HeManAndTheMastersOfTheUniverse1983 He-Man]] ended up as this during his fight against [[WesternAnimation/ThunderCats Lion-O]]. He just wanted to fend off Lion-O, but in doing so, [[spoiler:he crushed the Eye of Thundera, which kept the Thunderan race alive.]]
* ''WebAnimation/LlamasWithHats'': In episode 7, Paul [[spoiler:severs all ties with the series' AxCrazy VillainProtagonist Carl]], as any sane person would and should. However, it turns out that [[spoiler:Paul's friendship was the only thing keeping Carl a little bit sane (a very, ''very'' little bit), and without Paul around, Carl ends up destroying all life on Earth.]]
* In ''Machinima/RedVsBlue'':
** It's revealed in season 10 that [[spoiler:Carolina]]'s pride was responsible for nearly everything bad that happened to the Freelancers--[[spoiler:her original AI was Sigma, but she gave him up to Maine. Sigma and Maine went on to become the Meta and kill several other Freelancers. When she finally did get an AI, she took ''two'': the ones that were originally meant for Wash and South. South's jealousy due to her brother North getting an AI and her not led to South leaving North to die and shooting Wash in the back, and her own death at Wash's hands later. Wash, on the other hand, did get an AI... Epsilon. Which led to him going insane and plotting to take down the Director of Project Freelancer for his crimes.]] All because of pride.
** There's [[spoiler:the Director's obsession with his dead love, Allison. When the Alpha AI, copied from the Director's mind, was created, the Beta AI (based on the Director's memories of Allison) naturally fragmented from it. This inspired the Director to torture the Alpha into making more fragments, the ones mentioned above, to figure out a way to "get her right".]]
** There is also [[spoiler:the Sleeveless Insurrectionist Soldier, who shot Agent Maine in the throat several times, rendering him mute. This gave Carolina an excuse to give her A.I. Sigma away so that Maine could have an alternate way to speak. This contributed into forever turning him into the Meta.]]
** Season 14 ultimately reveals that [[spoiler:everything happened because Agent Florida tripped over a wire and broke it. Originally, had something happened to him, other Freelancers were to show up and take his place, starting with Agent California. However, by damaging the wire, the list of Freelancers were replaced by five other names, starting with Caboose. Thus, because of a damaged wire, Agent Florida would kick off a series of events that would lead to the destruction of the Freelancer Project.]]
* ''WebAnimation/{{RWBY}}'': During the Volume 6 Character Short, Ghira is troubled by [[MurderIsTheBestSolution Adam's]] violence and objects to him killing humans in front of him. [[WellIntentionedExtremist Sienna]] defends Adam, pointing out that he just saved Ghira's life. After having seen him fight and gone on several missions with him, she gives him control of the Vale branch of the [[WesternTerrorists White Fang]], praising his abilities and telling him that if he continues on the path he's on, he'll end up sitting by her side on the High Leader's throne. [[spoiler:What she [[UnwittingInstigatorOfDoom doesn't realise]] at that time, is that [[ANaziByAnyOtherName his path]] is not the one she thinks it is, and that [[GoneHorriblyRight it leads]] to him murdering her in Volume 5, [[KlingonPromotion usurping her throne]] and leading the militant White Fang that she created falling to a [[FantasticGhetto Menagerie army]] and the Mistral Police Force, thereby reinvigorating [[GentleGiant Ghira]], the peaceful leader she [[CategoryTraitor disapproved of and deposed]], into resuming control of the White Fang in order to create a brand new peaceful protest group.]]

[[folder:Web Comics]]
* In the ComicBook/ChickTract "Fatal Decision", Brutus, an orderly on the brink of being fired for rudeness to patients, makes hints that John shouldn't trust Dr. Bowers, leading to John destroying the vaccine and dying of his disease.
** The devils often invoke this trope, choosing someone who has an incidental relationship to the person whose soul they want to claim. In "The Assignment" they succeed in convincing Charles Bishop's subordinate's wife to badger him out of witnessing to his boss. They try to distract Cathy with a boy, only for it to fail when he proves to be a JerkAss, and try to have the previously mentioned subordinate call Bishop with a sales proposition, only for the angels to thwart this attempt twice. Charles ultimately dies in his sins, making the first example a successful one.
* In ''Webcomic/{{Freefall}}'', Florence has suspicions that Maxwell Post might be this when she learns that he is the spiritual advisor to the [[AIIsACrapshoot sapient robot]] population. [[SubvertedTrope So far, his efforts have been among the least of her worries.]]
* One ''Webcomic/ElGoonishShive'' storyline featured a rampaging boar which was enchanted to grow to an enormous size. Said enchantment is heavily implied to have come from [[spoiler:Rhoda]], who was unwittingly given a [[PowerTattoo magic mark]] and unknowingly used it on the boar while in a state of panic.
* Virtually everyone in ''Webcomic/{{Homestuck}}''; the ''single'' good character who doesn't manage this is Nepeta[[note]]largely because she's never shown actually ''doing'' much of anything; the one time she tries to do something significant she's hopelessly outclassed and dies pointlessly and almost immediately[[/note]].
** Tavros deserves special mention. At one point he attempts to save a young Jade from accidentally shooting herself by taking psychic control of her dog, Becquerel, and deflecting the shot at her grandfather (whom he believed was a hostile intruder), killing him. He then points out that Becquerel would have saved her even if he hadn't done anything (in a way that would not have killed Grandpa Harley) and that he only interfered so he could feel a little better about himself. Even when she points out that killing her grandfather was ''not'' appreciated, he still thinks he made the right choice.
* In ''Webcomic/KevinAndKell'', [[Webcomic/GeneralProtectionFault Nick and Ki's]] [[{{Crossover}} arrival in Domain]] by way of interdimensional travel disrupts the balance between the animal- and human-dominated worlds to the point at which the other two humans living on the animal side [[spoiler:Lindesfarne and Danielle]] are forced to leave lest the world suffer instinct loss. [[spoiler:Luckily, Catherine and Nigel do it instead]].
* In ''Webcomic/KidRadd'', two Moderators are given a large sum of money in order to hire an assassin to kill Radd, as Captain QB can't be directly implicated in illegal activities and needs to use a proxy. They reason that it can't be hard to kill someone in jail (as Radd is being imprisoned for illegally entering other games), and hire Kobayashi the discount ninja so that they can pocket the rest of the money. Radd survives the assassination attempt and Kobayashi becomes a recurring character who later meets up with Gnarl and, while training together, stumbles upon [[spoiler:Chimera Point, the keystone to Crystal's plans, which eventually results in ''her'' finding it too]].
* Several characters in ''Webcomic/{{minus}}'' take actions that, unbeknownst to them, lead to TheEndOfTheWorldAsWeKnowIt. First, a mysterious man pretty much "breaks" [[RealityWarper minus]] by stuffing her into a briefcase. She is freed, but becomes a CloudCuckooLander. In an attempt to cure her, the green-haired girl throws a rock at minus's head, causing her [[spoiler:[[LiterallyShatteredLives to shatter]]]]. Because she is now [[spoiler:a ghost]], minus starts to spend more time with her ghost friends than her live ones. Which leads to the biggest example of this trope in the comic: the red-haired ghost asks minus to bring her back to life, because she has some UnfinishedBusiness with certain humans that the readers don't get to see. minus agrees. Unfortunately, once the other ghosts find out, they demand that minus revive them too. She does, [[spoiler:only for the sheer influx of bodies on Earth to suffocate every living thing on the planet, including those who were just revived]]. [[SpaceWhaleAesop And that is why you should never ask anything of an omnipotent being, ever.]]
* In ''Webcomic/NobodyScores'' this is frequently the role of [[Main/{{CloudCuckoolander}} Jane Doe]]. [[http://nobodyscores.loosenutstudio.com/index.php?id=488 This]] for example.
* ''Webcomic/TheOrderOfTheStick'':
** [[KnightTemplar Miko Miyazaki]], having already [[DePower lost her Paladin abilities]] through the [[TheKingslayer unwarranted execution of of Lord Shojo]], ends up destroying the [[MacGuffin Sapphire Gate]], having once again misinterpreted what the gods wanted of her. Had she not been so hasty in doing this, the ghost of [[PrecursorHeroes Soon Kim]] could have permanently ended the threat of [[BigBad Xykon]] and [[DragonWithAnAgenda Redcloak]], who, themselves, were aiming for the gate, anyway.
** Right-Eye had the idea to recruit Xykon. If not for that one moment, Xykon never would have learned about the Snarl, probably never would have had the brains to become a lich on his own and would have continued his life of petty evil until he died and went to the Lower Planes without ever becoming the apocalyptic threat he is today.
** When Vaarsuvius went on a RoaringRampageOfRevenge and [[spoiler:cast Familicide, killing every creature related to the Ancient Black Dragon]], they didn't have any intentions beyond protecting their own family (and maybe enjoying the wildly DisproportionateRetribution way too much). Unfortunately for them, and also the world, [[spoiler:the Draketooth family guarding one of the Gates has a MeaningfulName, and Familicide wiped out every last one of them, leaving the Gate completely unprotected.]]

[[folder:Web Original]]
* Trouble in ''Roleplay/DinoAttackRPG'', being a mutant lizard who was adopted and trained by a member of the team trying to eradicate his kind, was the first to spark the tension between realist and idealist members of the team. Technically speaking he is responsible both for the campaigns by both Kotua ''and'' Cam O'Cozy, both of whom tried to commit genocide against idealist agents.
* ''WebVideo/DontHugMeImScared'':
** [[spoiler:Red Guy]] is heavily implied to be this in the fifth episode. At the beginning of the episode, Duck Guy and Yellow Guy note that something's "missing", unaware that it's [[spoiler:their friend Red Guy.]] Near the beginning of the episode, a phone rings, and when Duck Guy answers, he's suddenly in an operating room, watching himself on the television, with a mysterious voice saying "you have to know right from wrong". This seems to lead him to realize that the lesson would go wrong somehow and try to escape, [[spoiler:for which he is EatenAlive.]] The end credits imply that [[spoiler:the call was made by Red Guy, who somehow escaped from the lessons and was trying to help his friends escape, and hearing Red Guy's voice was what made Duck Guy realize what was going on. If it weren't for Red Guy, Duck Guy would probably still be alive, and Yellow Guy wouldn't be completely alone.]]
** The sixth video takes this further by implying that [[spoiler:Red Guy is [[GainaxEnding somehow]] inadvertently causing the GroundhogDayLoop the puppets are trapped in.]]
* ''Series/{{Noob}}'':
** In late Season 4, Kary commits the InnocentlyInsensitive act of [[spoiler:choosing to check out an in-game event over finishing her (in-game) wedding to Arthéon, who was taking it much more serously than she was.]] Arthéon was so furious that he went on a RoaringRampageOfRevenge. Even after he calmed down, he still had a much more cynical view of everyone and everything he knew than before. This became a really bad thing [[spoiler:because Arthéon eventually got a job that enabled him to impact the game's plot and the story has reached a point where he will be responsible for the game world's destruction unless his former guildmates stop him]].
** In late Season 5, Roxana keeps Saphir from doing a quest that impacts the game story and may have the side a effect of making Saphir's guild outrank Roxana's once it's done. The reason the quest could have been singlehandedly enough to significantly uprank Saphir's guild? It would bring a big blow to the BigBad if accomplished, help make him stronger if failed.
* In ''Wiki/SCPFoundation'', [[http://www.scp-wiki.net/scp-1867 SCP-1867 ("A Gentleman")]] is Lord Blackwood, an adventurous seaslug who appears in many other works telling about his adventurous times. If the accounts are correct, Lord Blackwood may have just been the one that [[spoiler: inspired SCP-319's maker to try and travel to another universe, and gave him the means to attempt it]]. A short read of that particular file lets us know that attempt essentially ''doomed this universe''.
* ''Literature/TheTimTebowCFLChronicles:'' Tim Tebow unintentionally destroys Canadian football. Unknown to him, the rest of the league can't start the 2014 playoffs until they get the results from his game against the REDBLACKS. But with Tebow leading the Argos' offense, and with [[{{Calvinball}} the utterly bizarre rules of "bound-for-street" play]], the game lasts ''over a decade''--while every other team can't do anything but wait.
* In ''Literature/{{Worm}}'', the Undersider's local [[TheSmartGuy Smart Girl]], Tattletale, normally isn't this, but a character flaw of hers is to start throwing everything her SherlockScan superpower picks up everywhere when she panics. This doesn't really hurt anyone...with the rather glaring exception of [[spoiler:cluing [[TheMedic Panacea]] into her family history...which sets off the [[DysfunctionJunction time bomb]] of issues that is her adopted family, and ends with Panacea's incarceration and her sister becoming a [[AndIMustScream miserable pile of immobile flesh]].]]

* ''WesternAnimation/AdventureTime'':
** The Ice King continually interferes with Finn's attempt to prevent [[VileVillainSaccharineShow the Lich]] from reaching the Well of Power and regaining his full power. As a result the Lich, having regained his full power by the time Finn and Jake finally reach him, [[NoHoldsBarredBeatdown ends up jobbing Finn]] and destroying the Gauntlet, the one weapon that can hurt him, forcing Finn to find an alternative. Then the Ice King accidentally drops Bubblegum into the Well, which melts her and allows the Lich to possess her. After being frozen with help from the Ice King, she shatters, requiring medical attention to be put back together. Part of Bubblegum is missing though, causing her to come back as a 13-year old, which later results in [[RoyalBrat Earl of Lemongrab]] assuming the throne, if only for an episode.
*** The snail was responsible for the Lich breaking free in the first place. He just happened to have crawled into Finn's backpack right before Princess Bubblegum took Finn and Jake to the location of [[CrystalPrison the Lich's imprisonment]]. As soon as he crawled out, the snail, having no psychic protection, was mind controlled by the Lich into freeing him and setting the above chain of events into place, not to mention the ongoing threat of the Lich when [[spoiler:the Lich possesses the snail directly]].
** If it weren't for an unnamed Scandinavian dock worker selling an old crown to an antiquarian [[spoiler:by the name of Simon Petrikov]], the Ice King would never have existed. However, if that happened then [[spoiler:Marceline]] would have most likely died in the [[AfterTheEnd post-apocalyptic wasteland]], so it isn't all bad.
** In the AlternateUniverse [[FanNickname "Farmworld"]], the Destiny Gang terrorising Finn's village and his family leads to ''him'' wearing the Ice King's crown, which in turn leads to the release of the Lich and the world being inflicted with ''another'' apocalypse.
* ''WesternAnimation/AvatarTheLastAirbender'': The Earth King informed Azula (disguised as a Kyoshi Warrior) of the invasion of the Fire Nation. Cue next season where the invasion force finds all royalty in hiding, and the invasion ends in failure with almost all of them captured. Zuko hoped this would lead to his father re-thinking his strategy with the war. Unfortunately, it did, but it led to Ozai plotting genocide on the Earth Kingdom.
** During a war council, Zuko is asked how the people of the Earth Kingdom would react to occupation. He honestly replies that as long as they had their pride, they would never give into the Fire Nation. His statement led to Ozai plotting genocide on the Earth Kingdom.
* In the one episode of ''WesternAnimation/ComboNinos'' where [[NotMeThisTime neither Diadoro nor Gomez]] had released any Divinos, Principal Bronka accidentally released a Family of snake-like Divinos.
* In the ''WesternAnimation/FostersHomeForImaginaryFriends'' special WesternAnimation/DestinationImagination, Herriman {{inter|ruptedCooldownHug}}feres with a resolution between the Face and the rest of the main characters, Frankie included, by scolding him, causing him to go berserk. Unlike most other examples of this trope, he immediately comes to regret this.
* In ''WesternAnimation/TheJungleBunch'', Ernest the Kiwi's machines, which are usually created for some mundane task (one being a machine that dug chunks of ice out of a mountain and delivered the piece to Ernest's drink) often tend to become a danger to the jungle that The Jungle Bunch has to stop.
* ''WesternAnimation/{{Kaeloo}}'': Stumpy is one in the episode "Let's Play the Quest for the Wholly Gruel". [[spoiler: He finds the titular Wholly Gruel, a magic crayon which can make anything it draws real, and uses it to doodle all over some hieroglyphics in a cave depicting characters who resemble him and his friends. He draws a meteorite about to strike them, and his real friends, meanwhile, almost get hit by an actual meteorite.]]
* Everything that went wrong in the ''WesternAnimation/{{Kissyfur}}'' episode "The Birds And The Bears", from the cubs taking Gus' paddlecab for a spin which eventually leads them through dangerous rapids to the gators taking control of the paddlecab and using it to capture the cubs, all happened thanks to [[OneEpisodeWonder Donna's]] rebellious behavior. She even [[LaserGuidedKarma gets called out for it]] when she and some of the other cubs are captured by the gators.
--> '''[[JerkAss Lenny]]:''' [[JerkassHasAPoint It was]] ''[[JerkassHasAPoint your]]'' [[JerkassHasAPoint dumb idea to fool with the paddlecab, Donna!]]\\
'''Duane:''' Yeah, it definitely wasn't a cool thing to do!\\
'''[[TheEeyore Stuckey]]:''' Not cool at all!
* This often happens in ''WesternAnimation/MiraculousLadybug'' where a character picks up the JerkassBall and accidentally drives someone into enough despair to be corrupted by BigBad Hawk Moth. The undisputed queen of this trope is AlphaBitch Chloé Bourgeois, who has a body count in the double digits.
* In the season 6 premiere episode for ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', Flurry Heart destroys the Crystal Heart, the magical artifact that protects the Crystal Empire by keeping out the arctic climate of the rest of the region. This results in a massive blizzard that threatens to destroy the entire kingdom and either drive off or ''kill'' the inhabitants. The unwitting part is because she's a ''baby [[WingedUnicorn alicorn]]''; she didn't intend to destroy it, she didn't even have the cognizance to realize what was going on. Fortunately, the Crystal Heart gets repaired and in the process seems to have helped brought her own power under control.
** The episode "Rock Solid Friendship" reveals that [[spoiler:Maud Pie inadvertently helped Starlight Glimmer take over "Our Town" with her cutie mark removal spell by informing her of a stone that could contain the magic]].
* A strange example of a fictional character ending up being one for the real-life events. ''WesternAnimation/TheRenAndStimpyShow'' had the minor character George Liquor getting brutally beaten up by Ren in the episode "Man's Best Friend". Said scene was later one of the reasons for creator Creator/JohnKricfalusi's firing.
* The third ''WesternAnimation/RobotChicken'' ''Franchise/StarWars'' special has an unnamed man suggest that Palpatine go into politics, which of course eventually leads to him becoming Emperor, the galactic war, the forming of the Empire, and the destuction of the Jedi. Said man is seen thirty years later realizing that it was all his fault and preparing to commit suicide...at least until ''Series/WheelOfFortune'' comes on.
* Many a ''{{WesternAnimation/Rugrats}}'' episode's plot gets kicked off by the babies misunderstanding something they hear from the adults:
** "The Old Country" has Tommy overhearing Stu talk about trying to "keep out the elements" while staying in a cabin in the woods, and misunderstanding him to think that elephants are going to crush them all.
** "The Legend of Satchmo" has Grandpa spooking the babies with a story about Sasquatch, prompting them to run off and get lost in the garden.
** "Reptar on Ice" has Angelica talking about how the dinosaurs went extinct, prompting the babies to think that [[HesJustHiding Reptar must be in hiding]] and so they wander off to find him at the titular ice show.
** "The Dog Broomer" has Tommy again mishearing 'dog groomer' as 'dog broomer' and is convinced that the woman hired to groom Spike is going to kidnap him - causing all sorts of trouble for her.
** "Dummi Bear Dinner Disaster" has the babies scheming to ruin a dinner party when Susie fears she might have to move if it goes well (her father is just having a business colleague over").
** "When Wishes Come True" has Drew bringing a statue of Angelica to the house, with the babies fearing that Angelica has somehow been TakenForGranite. Of course the expensive statue ends up broken in their attempts to revive her.
* Homer from ''WesternAnimation/TheSimpsons'' does this at least once or twice a season. He's even responsible for the death of Maude Flanders; Homer tells a group of bimbos to aim their [[ItMakesSenseInContext 'Free t-shirt' bazookas]] at him, only to duck at the last possible second as he grabs something off the ground. The barrage of t-shirts knocks Maude over the edge of the stadium to her death in front of her ''husband and two young children''.
-->'''Homer:''' I'm the one whose antics drove her out of her seat. I'm the one who provoked the lethal barrage of t-shirts. [[RuleOfThree I'm the one]] who parked in the ambulance zone, preventing any possible resuscitation.
* ''WesternAnimation/SouthPark'':
** The "Imaginationland" Trilogy has the Evil Imaginary characters when they killed all the terrorists who caused the war, killing any chance of the Evil characters knowing that the terrorists framed the Good Imaginary characters for attacking the Evil ones, so that the war would continue until [[KillEmAll both sides killed each other]]. But this would have been averted if the Evil characters actually ''won'' the war. [[spoiler:Instead, with the help of [[BigGood Butters]], the Good characters won the war. Since the Evil characters already [[MoralEventHorizon destroyed any excuse of them being as much pawns as the Good characters]], Butters refused to resurrect any Evil casualties and [[CruelMercy the survivors were imprisoned]]. So instead of literal "doom," they get a FateWorseThanDeath.]]
* ''WesternAnimation/WildKratts'': Bumper the baby sperm whale, and/or his mother, tend to crop up at inconvenient times that cause more trouble than help. Although friendly enough to the Wild Kratts team, just having such large animals arrive unexpectedly has caused Aviva to crash her hoverbike in "Sea Otter Swim", and forced Chris to abandon his giant squid Power Mode in "Seasquatch" for fear that ''other'' (and hungry!) sperm whales may be hanging around the mother/calf pair.

[[folder:Real Life]]
* Creator/SamuelTaylorColeridge had a vivid dream, got up and started writing it down as the epic poem ''Kubla Khan'', [[http://sydneypadua.com/2dgoggles/the-person-from-porlock/ but then there was a knock at the door]], and a man from the nearby town of Porlock kept him talking just long enough to forget all about the dream and he never finished it. The [[http://en.wikipedia.org/wiki/Person_from_Porlock Person from Porlock]] is now literary shorthand for an unwanted visitor.
** Though some have theorized that Coleridge never intended to finish the poem (or that it was finished already), and he made up the story of the visitor just to mess with people. It doesn't help that Coleridge was a heavy opiate user, and the "dream" could have been something more of a "drug-induced vision," and the man from Porlock may or may not have actually been there. (Cue images of a poet standing on his doorstep talking to nobody while hazy visions of Kublai Khan's utopia dissipate into the aether.)
* UsefulNotes/ChristopherColumbus's voyages opened up the Americas to the Old World, bringing over disease which wiped out 90% of the Native Americans.
* Andy Dick. At a 1997 Christmas party, he reintroduced Brynn Omdahl, wife of Creator/PhilHartman, to cocaine, leading to his death. Which led to Andy Dick [[KickTheDog making some tasteless jokes about his role in Hartman's death,]] which resulted in Hartman's friend Creator/JonLovitz kicking his ass. It appears that Dick lives up to his name.
* Floyd Wells. He told fellow cons Perry Smith and Richard Hickock that a farmer he worked for named Herb Clutter kept a safe hidden with plenty of cash inside. As it turned out, there was no safe. It was this false info that led Smith and Hickock to massacre Mr. Clutter and his family, the basis for Creator/TrumanCapote's ''Literature/InColdBlood''.
* A rare inversion in [[http://en.wikipedia.org/wiki/Stanislav_Petrov Stanislav Petrov]]. While monitoring a satellite for the Soviet early warning system of a nuclear attack, he received a report of five inbound [=ICBMs=]. He decided it didn't make sense for a US first strike to be composed of only five nukes, he logged it as a technical error and overrode the command to launch a massive retaliation strike. Had he not been so cautious, WorldWarIII surely would have erupted.
* The failure of the Jay Leno Show on primetime had this effect on Creator/ConanOBrien's tenure as host of ''Series/TheTonightShow'', as it damaged local 11pm newscast ratings, as well as Conan himself, leading NBC to move Jay and his show back to his old 11:35 spot, and pushing Conan just past midnight. Conan, [[JudgmentOfSolomon not wanting to tarnish the legacy of the Tonight Show]], wanted no part of the agreement, and was subsequently evicted from the show, with Jay back as host.
* Senator Stephen Douglas, the man responsible for the Kansas-Nebraska Act. Originally, his intentions had simply been to get a railroad to California built, which would start in Chicago, Illinois (his home state). To do this, he proposed splitting the remaining unorganized chunk of the Louisiana Territory into the territories of Kansas and Nebraska. Pro-slavery Southerners slipped in a part saying that the legality of slavery in each territory would be decided by the voters there. But then pro-slavery advocates from Missouri flooded into Kansas to support slavery, resulting in "Bleeding Kansas", the prequel to UsefulNotes/TheAmericanCivilWar. Douglas himself has been branded pro-slavery for many years afterward following the fallout, with historians often leaving out that it was the South that suggested the decision of slavery by popular sovereignty and that Douglas himself simply wanted to build a railroad to California, obviously having no idea that the first planned transcontinental railroad would cause [[UsefulNotes/TheAmericanCivilWar the biggest schism ever to hit the United States]] over completely unrelated circumstances.
* In 2007, Creator/AdultSwim launched a guerrilla marketing campaign for the ''WesternAnimation/AquaTeenHungerForce'' [[TheMovie movie]] featuring battery-powered LED placards resembling the Mooninite characters being placed in numerous places around the US. However in Boston, police officials mistakenly thought that the [=LEDs=] were bombs, and treated the whole event as such. This event would turn out to known as the [[http://en.wikipedia.org/wiki/2007_Boston_bomb_scare Boston Bomb Scare]], which led to legal implications being placed on Turner Broadcasting and their contractors, the internet to make mock [[MemeticMutation "Never Forget" memes]], and forced then-current Creator/CartoonNetwork head Jim Samples to step down. It wouldn’t be long after until fans began to realize that Creator/CartoonNetwork would not be the same since the incident. Not because of any legal incidents, but because Sample’s replacement, Stuart Snyder, became the instigator of the channel’s infamous NetworkDecay, and an increase in Live action, and sitcom style shows.
* Franz von Papen, ex-Chancellor of the Weimar Republic, who in 1933 convinced President Hindenburg to make UsefulNotes/AdolfHitler chancellor in order to save his own political hide. By this point, the Nazis (forced by previous chancellors to fight repeated elections which sapped their funds) were rapidly losing support and were scraping the bottom of their piggy bank.
* Marinus van der Lubbe, the guy who started the Reichstag fire. He was a raving madman who was quickly captured that same night. It gave the Nazis the perfect opportunity to seize power, as the aforementioned repeated elections would eventually end in a loss of NSDAP seats.
* In the mid-'80s bribery scandal linked to R. Budd Dwyer (the inspiration behind "Hey Man, Nice Shot" by Music/{{Filter}}), William Smith, an attorney linked to the case, gave dubious testimony in order to accept a plea bargain, which made a guilty verdict for the former practically inevitable. As a result, Dwyer himself [[AteHisGun publicly committed suicide]] the day before the sentencing was to have taken place.
* In the night of April 14, 1912 Jack Phillips, radio operator of the ''RMS Titanic'', received a message alerting of an ice field ahead from the radio operator of the ''SS Californian'', Cyril Evans. The message interrupted an information directed to a first class passenger from Cape Race, Newfoundland, and Phillips radioed "Shut up, shut up! I am busy; I am working Cape Race!" back to Evans. Annoyed, Evans turned off the radio and went to sleep... ten minutes before the ''Titanic'' struck an iceberg. This prevented the ''Californian'' (who was the closest ship to the ''Titanic'') from hearing the ''Titanic'''s repeated distress calls and rescuing her passage before the ship went down.
* David Blair was originally slated to be Second Officer of the ''Titanic'' during her maiden voyage. However, in the last moment White Star reassigned the more experienced Henry Wilde, Chief Officer of the ''Olympic'' (at the time in drydock) to the ''Titanic'', and the knock-off effect was Blair being given another post out of the ship. By accident, Blair left with a key from the ''Titanic'', that turned out to be the only key to a safe in the Crow's Nest keeping the lookouts' binoculars. Without binoculars, the lookouts failed to see the iceberg in time.
* Jamie Gorelick, during her tenure as Deputy US Attorney General, was responsible for strengthening the restrictions on information sharing between domestic and foreign intelligence services. [[RightHandVersusLeftHand The lack of coordination]] this caused lead directly to the US government's failure to prevent the September 11th attacks, despite ample evidence of the plot, up to and including one of the terrorists being (briefly) taken into custody not long before it happened.
* Creator/SethRogen has become this with regards to the now-notorious consequences from ''Film/TheInterview'' and the cost it left Sony with. He knew that the film would piss off North Korea, and went ahead with it, presumably figuring that the DPRK would once again fail to follow up on its threats. However, he probably couldn't have seen his move as coming at the cost of the financial stability of the company he was working for, or The Guardians of Peace outright threatening terrorist attacks in theatres where it was due to play.
* On April 20, 2007, Davon Boddie was arrested for pot dealing outside of the Royal Suite nightclub in Roanoke, Virginia. Boddie was the cousin of [[UsefulNotes/AmericanFootball Atlanta Falcons quarterback]] Michael Vick, and gave Vick's home address as his own. Five days later, police searched the home and discovered a massive [[http://en.wikipedia.org/wiki/Bad_Newz_Kennels_dog_fighting_investigation dog-fighting ring]], leading to the arrest and conviction of Vick and four others.
* Gavrilo Princip and his co-conspirators in the assassination of Archduke Franz Ferdinand. All they wanted was a re-arrangement of some political borders in one part of the Balkans. What they got was a world-spanning war which was the deadliest in history, which led to the fall of the European colonial powers and the rise of communism, ''another'' world-spanning war 20 years later which became the new most deadliest war in history as a result of the mess the previous one left, and a subsequent cold war due to the results of the previous war that kept the world on the brink of destruction for fifty years. [[ArsonMurderAndJaywalking Oh, and that Balkan situation never was properly sorted out.]]
** To take it a step further, Ferdinand's driver, who was supposed to be taking him visit some people in the hospital, got lost, tried to reverse, and stalled the car almost exactly where Princip happened to be at that exact moment. Probably the most consequential wrong turn in human history.
* The TGWTG WebVideo/ToBoldlyFlee movie had a lot of effort and a lot of time put into it, but it was also a big TroubledProduction with many producers having bad memories of filming. As shown in the behind the scenes feature, things were apparently running smoothly until Rob Walker had the bright idea to lie about running fifteen minutes late. You can see Doug's face fall when he's told this, and according to [[WebVideo/TheNostalgiaChick Lindsay]] and [[WebVideo/ToddInTheShadows Todd]], that's when things started to break down.
* Best Buy's acquisition of Musicland in 2001 and their subsequent gross negligence, including making it ''[[EpicFail hemorrhage $80 million]]'' '''''[[EpicFail in one year]]''''' before selling it the following year, ultimately drove it to bankrupcy, leading to a mass closing of stores before being brought by Trans World Entertainment (owner of competitor FYE) in 2006. The mass closing of stores caused unsold stock to be taken back to the warehouses. While this has affected all home video companies, anime companies (who were 100% reliant on home video sales due to the lack of digital distribution rights at the time because [[ExecutiveMeddling the Japanese licensors refused to give them those rights]] as [[InsaneTrollLogic they equated legal digital distribution with piracy]]) were particularly severely affected, leading to the crash of the North American anime industry by the end of the 2000s, including the closures of Creator/{{ADV Films}}, Creator/{{Geneon}} and Creator/CentralParkMedia, and the downsizing and eventual closure of Creator/BandaiEntertainment. On the general side, the mass closing of the stores led to a decline of home video sales, which was further exacerbated by the growing ubiquity of streaming services such as Hulu and Netflix.
* Robert Campbeau's expansion into the United States resulted in the demise of the regional department store in the United States. To wit, Campbeau purchased Allied Stores and Federated Stores in the 1980s through junk bond [=LBOs=] but Campbeau was unable to pay it off. This, combined with a downturn in the retail industry at the time, has resulted in what many called the largest bankruptcy in U.S. history. This bankruptcy ultimately caused Macy's to start cannibalizing off stores that it inherited from both corporations beginning in the 1990s, and later on the May Department Stores company when that was merged into Macy's in 2005-2006.
* [[WesternTerrorists Dylann Storm Roof]], a white supremacist who took pictures of himself with Confederate memorabilia some time prior, shot up a church in Charleston with the hopes of dividing the nation. Not only did he [[EpicFail fail spectacularly]], he also caused collateral damage when his actions, which turned the general public (even in the South) against the Confederate flag, managed to TARFU ''Series/TheDukesOfHazzard''[='=]s reputation, if not outright FUBAR it.
* Roof's actions helped precipitate the rise of the alt-right, and subsequently the "Unite The Right" white supremacist rally at the University of Virginia in Charlottesville. Unfortunately for the alt-right, the rally caused a national crisis after one of the rallygoers mowed down a group of counterprotesters with his car, killing a young woman and injuring nineteen other people. The fallout from the attacks crippled the movement's momentum, with members losing jobs and being blacklisted from the internet. A nationwide sea change in attitudes about racism occurred, and the public began to turn against confederate imagery (as the Charlottesville protest was against the removal of a Robert E. Lee statue). The reputations of President Donald Trump and the Republican Party took a massive blow due to Trump's widely-panned response to the protest. The right's fight against antifa, the anti-fascist anarchist group who joined more peaceful counterprotesters to fight the white supremacists, was severely harpooned by the left's growing sympathy to the movement, as it was increasingly difficult to criticize a group, no matter how misguided, who fought on the same side as those killed in a terrorist attack. Most ironically, despite being called the "Unite the Right" rally, the aftermath rally ultimately divided the right and united the ''left''. Other organizations who got blamed for the rally include the ACLU, who defended the rights of the protesters, and the Charlottesville police, who did little to stop clashes between the two groups and thus failed to prevent the terrorist attack from occuring.
* The UsefulNotes/PunicWars was started by a band of mercenaries called the Mamertines who took over the city of Messana, and the Romans and the Carthaginians turn their attention away from them and then against each other over control of Sicily. What followed was years of bloody wars between the two empires, which finally ended with the destruction of Carthage.
* Faida Hamdi was a Tunisian government worker. In late 2010, she had a confrontation with a street vendor and confiscated the vendor's cart. The vendor [[SelfImmolation set himself in fire]] as a protest in front of a government building. His death [[UsefulNotes/TheArabSpring led to protests across the Middle East]] and the protests soon turned to devastating wars that would go on to shake the whole world. Today, Hamdi [[http://www.telegraph.co.uk/news/worldnews/africaandindianocean/tunisia/12054657/I-started-the-Arab-Spring.-Now-death-is-everywhere-and-extremism-blooming.html wonders]] WhatCouldHaveBeen if she did not have that initial confrontation.
* Michael Dukakis authorized weekend passes for prisoners while Governor of Massachusetts. One recipient of these weekend passes, Willie Horton, kidnapped, murdered, and raped one weekend. This ended up costing Dukakis the 1988 Presidential election after vice president George H.W. Bush's campaign pushed this heavily in an advertising campaign, and made politicians wary of being honest about their stances on crime, which led to the sudden toughening of criminal laws under Bill Clinton.
* Portuguese missionaries who threatened to conquer Japan through the forced spread of Christianity were directly responsible for centuries of de jure xenophobia in the country, which only started to be loosened (key word: started, only in 2017 did discrimination against foreigners living in the country start to significantly fade in earnest) when Matthew Perry opened trade routes between the United States and Japan in the middle of the 19th century via GunboatDiplomacy.
* The good people of Spain probably had no idea they were making world history beyond the scope of their own country when they toppled Isabela III in 1868. As even many of the revolutionaries did not even think of a Republic as a possible solution, they searched Europe for a potential King (or perhaps Queen). In the course of this search, they also contacted [[https://en.wikipedia.org/wiki/Leopold,_Prince_of_Hohenzollern Leopold of Hohenzollern]], a good Catholic, a family man in his mid thirties who seemed altogether a good candidate for the Spanish throne by the standards of the time. There was only one problem: as you might have guessed from his name, he was a (distant) relative of the Hohenzollern dynasty in Prussia and French emperor Napoleon III feared having German speaking kings in his east and west, so Leopold ultimately declined. This could have been the end of it, and indeed in most cases it would have, but Napoleon III being Napoleon III, he was not content with Leopold himself refusing, he wanted the Prussian king to renounce any claim of any Hohenzollern to the Spanish throne now and in the future. In 1870 the French ambassador bothered the Prussian King Wilhelm at a health spa in Bad Ems where the emperor was enjoying a ''Kur''[[note]]Basically a holiday that is supposed to cure ailments, still popular with Germans today[[/note]] and while the French ambassador was rude, the king was cordial and polite but basically told him "We've talked about this before, Leopold has already rejected, I am not him and I can't give promises for what my heirs might do". Unsatisfied, the French ambassador tried to bother the Prussian King again but the Prussian King in essence had a high ranking nobleman (sending anybody less would have been an affront) tell the French ambassador essentially the same thing again and that further discussing the issue was obviously pointless, the facts being what they were. Wilhelm then sent a report about those events in a telegram to his Prime Minister Otto von Bismarck. Bismarck saw an opportunity there and had the telegram shortened so that it could be read as the Prussian King rudely refusing to even meet with the ambassador (which would be diplomacy talk for "shove it up your ***") and to add insult to injury having that message delivered through some page. While Bismarck did ''not'' as he was often accused of QuoteMine the telegram, the French press published the shortened version and the reaction Bismarck intended occurred. France was furious, the emperor wanted to secure his domestic position threatened by previous foreign policy blunders[[labelnote:examples]]Like supporting Austria in the Austro-Prussian war but not actually intervening, which resulted in military loss for Austria, being outmaneuvered in the Italian wars of independence which France won for the Italians in large part but had nothing to show for except Nice or the disaster that was the Mexican Expedition which installed the brother of Austrian Emperor Franz Joseph as emperor only to have the Mexican Emperor turn rogue and end in front of a Mexican firing squad[[/labelnote]] as well as increasing demands for political liberalization and thus an ill-prepared France launched a war over what was seen by virtually everybody in Europe as a nothing-burger. France had hoped to beat Prussia and maybe call some allies to their side if the fight took longer. Not only did nobody ally with France, but all German states except Austria (which stayed neutral) rallied to the Prussian cause to fulfill secret defensive treaties. And then Napoleon III was captured near Sedan. While the newly declared Third Republic fought on, Prussia utterly wiped the floor with the French Army and ultimately France had to accept a humiliating peace treaty, that cost her five billion Francs in gold, Alsace and Lorraine and an immensurable sum in clout, credibility and respect around the world. To add insult to injury, a new German Empire was declared ''in Versailles''. This slight of course caused desire on the French part for revenge, which became one of the ultimate causes for UsefulNotes/WorldWarI which the Germans lost, causing desire for revenge in them, ultimately leading to UsefulNotes/WorldWarII. Thanks for asking about that Royal Succession thing, Spain.
* On July 1st, 2002, Swiss air traffic controller Peter Nielsen, overworked and under-equipped, spotted two planes on a collision course and ordered one of them to descend. Unfortunately, due to his workload and the fact that key pieces of his system were offline, he failed to realize that the other plane was already descending in compliance with an automated collision avoidance system, and that instead of moving the first plane ''out'' of the second plane's path, he was instead ensuring they remained ''in'' it. Predictably, the two planes collided, killing everyone on board both flights. ([[RoaringRampageOfRevenge Nielsen himself was later murdered in an act of vengeance by a man whose entire family had died in the disaster.]])
* One fateful day in 1921, a random black man in Tulsa stepped into an elevator operated by a white girl. To this day, the events of what really happened remain unknown, but regardless, the incident set off a chain reaction leading to the destruction of Greenwood Avenue.
* A barbecue held by Bruce Pearl, then-head coach of the Tennessee Volunteers basketball team, only fueled the fire of Fulmer's Revenge and ensured that it could not only not be put out on the football side, where it had originated, as soon as then-head coach Derek Dooley would've liked, it also cost Dooley his job, spread to the rest of UT athletics, and became a major wildfire, as it were. What's worse is that [[ArsonMurderAndJaywalking Pearl's successor, Cuonzo Martin, never really got to show off his true potential as a UT basketball coach in the three seasons he was with UT before he resigned to coach the California Golden Bears]].

** [[spoiler:Otome and Makoto]] might be even worse ones in some routes. It's depending on Makoto pulling one or another action that [[spoiler:Otome will or not tell Makoto's best friend Taisuke that girls like forceful dudes during sex -- which will lead him to rape his crush Kotonoha, under the very stupid belief that the poor girl's barely whispered "no, don't..." are actually a part of the "protest pretend" kink. [[note]]where the passive partner in hentai/ecchi/hard yaoi/etc. media fakes being embarrassment and unwillingness.[[/note]].]]
** Also, [[spoiler: Nanami, Hikari and Otome's GirlPosse]] can become the trope, when [[spoiler: they '''horribly''' bully Kotonoha to [[ShippingTorpedo keep her away from Makoto]] [[ShipperOnDeck and make sure Sekai gets him]].]] This can either lead to [[spoiler: Makoto ''completely cutting Sekai off his life'' before choosing Kotonoha since he thinks she's the one instigating the bullying that Koto has been a victim of [[note]](she's almost surely '''not''', but Makoto is simply too angry to consider that because school bullying is his BerserkButton)[[/note]] ]] or to [[spoiler: Kotonoha [[GoMadFromtheRevelation breaking down so badly]] for said harrassment that ''she murders Sekai in broad daylight''.]] In either way, their support to one girl over the other ''makes things MUCH worse for the one they wanted to "help"''.
* ''VisualNovel/UminekoWhenTheyCry'':
** [[spoiler:Battler Ushiromiya]] of all people, who drives [[spoiler:Sayo Yasuda]] to orchestrate the murders [[spoiler:by unwittingly breaking a promise to take them away from Rokkenjima]]. Battler didn't come back for it because of ''very'' serious family issues (depicted below), but unfortunately, [[spoiler:the already broken Sayo]] took this very, ''very'' badly.
** Furthermore, if that's the case, then [[spoiler: ''Rudolf and Kyrie'']] are also responsible. [[spoiler: Had they not [[ParentWithNewParamour married too soon after the death of Battler's beloved mother]] for the teenage Battler's taste, he would have not broken ties with his paternal family. Therefore, he would've showed up in Rokkenjima sooner and/or more frequently and, as the GuileHero he is, he would've found a way to help poor Sayo deal with their crappy situation, promise or not.]]
** There's also [[spoiler:Natsuhi]], who is largely responsible for [[spoiler:Sayo Yasuda]]'s issues in the first place. [[spoiler:Sayo was pretty much forcibly given to her by Kinzo as a baby to raise after she couldn't give birth to an heir, which [[GoodIsOldFashioned the very traditional Natsuhi]] saw as a reminder of her "failure" as a woman. One day, out of anger and resentment out of having to raise a child that wasn't her own, Natsuhi completely lost it and pushed a servant holding the baby off a cliff. The servant died but the baby survived, though with injuries that damaged their sexual organs, leading to Sayo having major gender/body issues later in life, which would ''not'' exactly help with their increasingly unstable mental state. An alternate continuity shows that, had Natsuhi not snapped the way she did, Sayo would grow into the [[TheAce far more stable]] [[AlternateSelf Lion Ushiromiya]].]]
* In ''VisualNovel/ZeroTimeDilemma'', Zero mentions a story of how a ''snail'' caused 6 deaths by just being where it was. A woman [[spoiler: heavily hinted to be Eric's mother]] used a different way than usual because a snail was on the usual one. This caused her to meet a young SerialKiller, [[spoiler: who turns out to be Mira]], and get killed. An innocent man [[spoiler: later revealed to be Akane's father]] was caught and sentenced to death, which lead to his wife to commit suicide. The man was going to catch a taxi but he couldn't, and the taxi driver took a surgeon going to operate a kid. The taxi had an accident and both the driver and the surgeon died. Since the kid never received his surgery, he died as well. [[ArcWords Life is simply unfair]]

He just wanted to fend off Lion-O, but in doing so, [[spoiler:he crushed the Eye of Thundera, which kept the Thunderan race alive.]]
* ''WebAnimation/LlamasWithHats'': In episode 7, Paul [[spoiler:severs all ties with the series' AxCrazy VillainProtagonist Carl]], as any sane person would and should. However, it turns out that [[spoiler:Paul's friendship was the only thing keeping Carl a little bit sane (a very, ''very'' little bit), and without Paul around, Carl ends up destroying all life on Earth.]]
* In ''Machinima/RedVsBlue'':
** It's revealed in season 10 that [[spoiler:Carolina]]'s pride was responsible for nearly everything bad that happened to the Freelancers--[[spoiler:her original AI was Sigma, but she gave him up to Maine. Sigma and Maine went on to become the Meta and kill several other Freelancers. When she finally did get an AI, she took ''two'': the ones that were originally meant for Wash and South. South's jealousy due to her brother North getting an AI and her not led to South leaving North to die and shooting Wash in the back, and her own death at Wash's hands later. Wash, on the other hand, did get an AI... Epsilon. Which led to him going insane and plotting to take down the Director of Project Freelancer for his crimes.]] All because of pride.
** There's [[spoiler:the Director's obsession with his dead love, Allison. When the Alpha AI, copied from the Director's mind, was created, the Beta AI (based on the Director's memories of Allison) naturally fragmented from it. This inspired the Director to torture the Alpha into making more fragments, the ones mentioned above, to figure out a way to "get her right".]]
** There is also [[spoiler:the Sleeveless Insurrectionist Soldier, who shot Agent Maine in the throat several times, rendering him mute. This gave Carolina an excuse to give her A.I. Sigma away so that Maine could have an alternate way to speak. This contributed into forever turning him into the Meta.]]
** Season 14 ultimately reveals that [[spoiler:everything happened because Agent Florida tripped over a wire and broke it. Originally, had something happened to him, other Freelancers were to show up and take his place, starting with Agent California. However, by damaging the wire, the list of Freelancers were replaced by five other names, starting with Caboose. Thus, because of a damaged wire, Agent Florida would kick off a series of events that would lead to the destruction of the Freelancer Project.]]
* ''WebAnimation/{{RWBY}}'': During the Volume 6 Character Short, Ghira is troubled by [[MurderIsTheBestSolution Adam's]] violence and objects to him killing humans in front of him. [[WellIntentionedExtremist Sienna]] defends Adam, pointing out that he just saved Ghira's life. After having seen him fight and gone on several missions with him, she gives him control of the Vale branch of the [[WesternTerrorists White Fang]], praising his abilities and telling him that if he continues on the path he's on, he'll end up sitting by her side on the High Leader's throne. [[spoiler:What she [[UnwittingInstigatorOfDoom doesn't realise]] at that time, is that [[ANaziByAnyOtherName his path]] is not the one she thinks it is, and that [[GoneHorriblyRight it leads]] to him murdering her in Volume 5, [[KlingonPromotion usurping her throne]] and leading the militant White Fang that she created falling to a [[FantasticGhetto Menagerie army]] and the Mistral Police Force, thereby reinvigorating [[GentleGiant Ghira]], the peaceful leader she [[CategoryTraitor disapproved of and deposed]], into resuming control of the White Fang in order to create a brand new peaceful protest group.]]

** The devils often invoke this trope, choosing someone who has an incidental relationship to the person whose soul they want to claim. In "The Assignment" they succeed in convincing Charles Bishop's subordinate's wife to badger him out of witnessing to his boss. They try to distract Cathy with a boy, only for it to fail when he proves to be a JerkAss, and try to have the previously mentioned subordinate call Bishop with a sales proposition, only for the angels to thwart this attempt twice. Charles ultimately dies in his sins, making the first example a successful one.
* In ''Webcomic/{{Freefall}}'', Florence has suspicions that Maxwell Post might be this when she learns that he is the spiritual advisor to the [[AIIsACrapshoot sapient robot]] population. [[SubvertedTrope So far, his efforts have been among the least of her worries.]]
* One ''Webcomic/ElGoonishShive'' storyline featured a rampaging boar which was enchanted to grow to an enormous size. Said enchantment is heavily implied to have come from [[spoiler:Rhoda]], who was unwittingly given a [[PowerTattoo magic mark]] and unknowingly used it on the boar while in a state of panic.
* Virtually everyone in ''Webcomic/{{Homestuck}}''; the ''single'' good character who doesn't manage this is Nepeta[[note]]largely because she's never shown actually ''doing'' much of anything; the one time she tries to do something significant she's hopelessly outclassed and dies pointlessly and almost immediately[[/note]].
** Tavros deserves special mention. At one point he attempts to save a young Jade from accidentally shooting herself by taking psychic control of her dog, Becquerel, and deflecting the shot at her grandfather (whom he believed was a hostile intruder), killing him. He then points out that Becquerel would have saved her even if he hadn't done anything (in a way that would not have killed Grandpa Harley) and that he only interfered so he could feel a little better about himself. Even when she points out that killing her grandfather was ''not'' appreciated, he still thinks he made the right choice.
* In ''Webcomic/KevinAndKell'', [[Webcomic/GeneralProtectionFault Nick and Ki's]] [[{{Crossover}} arrival in Domain]] by way of interdimensional travel disrupts the balance between the animal- and human-dominated worlds to the point at which the other two humans living on the animal side [[spoiler:Lindesfarne and Danielle]] are forced to leave lest the world suffer instinct loss. [[spoiler:Luckily, Catherine and Nigel do it instead]].
* In ''Webcomic/KidRadd'', two Moderators are given a large sum of money in order to hire an assassin to kill Radd, as Captain QB can't be directly implicated in illegal activities and needs to use a proxy. They reason that it can't be hard to kill someone in jail (as Radd is being imprisoned for illegally entering other games), and hire Kobayashi the discount ninja so that they can pocket the rest of the money. Radd survives the assassination attempt and Kobayashi becomes a recurring character who later meets up with Gnarl and, while training together, stumbles upon [[spoiler:Chimera Point, the keystone to Crystal's plans, which eventually results in ''her'' finding it too]].
* Several characters in ''Webcomic/{{minus}}'' take actions that, unbeknownst to them, lead to TheEndOfTheWorldAsWeKnowIt. First, a mysterious man pretty much "breaks" [[RealityWarper minus]] by stuffing her into a briefcase. She is freed, but becomes a CloudCuckooLander. In an attempt to cure her, the green-haired girl throws a rock at minus's head, causing her [[spoiler:[[LiterallyShatteredLives to shatter]]]]. Because she is now [[spoiler:a ghost]], minus starts to spend more time with her ghost friends than her live ones. Which leads to the biggest example of this trope in the comic: the red-haired ghost asks minus to bring her back to life, because she has some UnfinishedBusiness with certain humans that the readers don't get to see. minus agrees. Unfortunately, once the other ghosts find out, they demand that minus revive them too. She does, [[spoiler:only for the sheer influx of bodies on Earth to suffocate every living thing on the planet, including those who were just revived]]. [[SpaceWhaleAesop And that is why you should never ask anything of an omnipotent being, ever.]]
* In ''Webcomic/NobodyScores'' this is frequently the role of [[Main/{{CloudCuckoolander}} Jane Doe]]. [[http://nobodyscores.loosenutstudio.com/index.php?id=488 This]] for example.
* ''Webcomic/TheOrderOfTheStick'':
** [[KnightTemplar Miko Miyazaki]], having already [[DePower lost her Paladin abilities]] through the [[TheKingslayer unwarranted execution of of Lord Shojo]], ends up destroying the [[MacGuffin Sapphire Gate]], having once again misinterpreted what the gods wanted of her. Had she not been so hasty in doing this, the ghost of [[PrecursorHeroes Soon Kim]] could have permanently ended the threat of [[BigBad Xykon]] and [[DragonWithAnAgenda Redcloak]], who, themselves, were aiming for the gate, anyway.
** Right-Eye had the idea to recruit Xykon. If not for that one moment, Xykon never would have learned about the Snarl, probably never would have had the brains to become a lich on his own and would have continued his life of petty evil until he died and went to the Lower Planes without ever becoming the apocalyptic threat he is today.
** When Vaarsuvius went on a RoaringRampageOfRevenge and [[spoiler:cast Familicide, killing every creature related to the Ancient Black Dragon]], they didn't have any intentions beyond protecting their own family (and maybe enjoying the wildly DisproportionateRetribution way too much). Unfortunately for them, and also the world, [[spoiler:the Draketooth family guarding one of the Gates has a MeaningfulName, and Familicide wiped out every last one of them, leaving the Gate completely unprotected.]]

[[folder:Web Original]]
* Trouble in ''Roleplay/DinoAttackRPG'', being a mutant lizard who was adopted and trained by a member of the team trying to eradicate his kind, was the first to spark the tension between realist and idealist members of the team. Technically speaking he is responsible both for the campaigns by both Kotua ''and'' Cam O'Cozy, both of whom tried to commit genocide against idealist agents.
* ''WebVideo/DontHugMeImScared'':
** [[spoiler:Red Guy]] is heavily implied to be this in the fifth episode. At the beginning of the episode, Duck Guy and Yellow Guy note that something's "missing", unaware that it's [[spoiler:their friend Red Guy.]] Near the beginning of the episode, a phone rings, and when Duck Guy answers, he's suddenly in an operating room, watching himself on the television, with a mysterious voice saying "you have to know right from wrong". This seems to lead him to realize that the lesson would go wrong somehow and try to escape, [[spoiler:for which he is EatenAlive.]] The end credits imply that [[spoiler:the call was made by Red Guy, who somehow escaped from the lessons and was trying to help his friends escape, and hearing Red Guy's voice was what made Duck Guy realize what was going on. If it weren't for Red Guy, Duck Guy would probably still be alive, and Yellow Guy wouldn't be completely alone.]]
** The sixth video takes this further by implying that [[spoiler:Red Guy is [[GainaxEnding somehow]] inadvertently causing the GroundhogDayLoop the puppets are trapped in.]]
* ''Series/{{Noob}}'':
** In late Season 4, Kary commits the InnocentlyInsensitive act of [[spoiler:choosing to check out an in-game event over finishing her (in-game) wedding to Arthéon, who was taking it much more serously than she was.]] Arthéon was so furious that he went on a RoaringRampageOfRevenge. Even after he calmed down, he still had a much more cynical view of everyone and everything he knew than before. This became a really bad thing [[spoiler:because Arthéon eventually got a job that enabled him to impact the game's plot and the story has reached a point where he will be responsible for the game world's destruction unless his former guildmates stop him]].
** In late Season 5, Roxana keeps Saphir from doing a quest that impacts the game story and may have the side a effect of making Saphir's guild outrank Roxana's once it's done. The reason the quest could have been singlehandedly enough to significantly uprank Saphir's guild? It would bring a big blow to the BigBad if accomplished, help make him stronger if failed.
* In ''Wiki/SCPFoundation'', [[http://www.scp-wiki.net/scp-1867 SCP-1867 ("A Gentleman")]] is Lord Blackwood, an adventurous seaslug who appears in many other works telling about his adventurous times. If the accounts are correct, Lord Blackwood may have just been the one that [[spoiler: inspired SCP-319's maker to try and travel to another universe, and gave him the means to attempt it]]. A short read of that particular file lets us know that attempt essentially ''doomed this universe''.
* ''Literature/TheTimTebowCFLChronicles:'' Tim Tebow unintentionally destroys Canadian football. Unknown to him, the rest of the league can't start the 2014 playoffs until they get the results from his game against the REDBLACKS. But with Tebow leading the Argos' offense, and with [[{{Calvinball}} the utterly bizarre rules of "bound-for-street" play]], the game lasts ''over a decade''--while every other team can't do anything but wait.
* In ''Literature/{{Worm}}'', the Undersider's local [[TheSmartGuy Smart Girl]], Tattletale, normally isn't this, but a character flaw of hers is to start throwing everything her SherlockScan superpower picks up everywhere when she panics. This doesn't really hurt anyone...with the rather glaring exception of [[spoiler:cluing [[TheMedic Panacea]] into her family history...which sets off the [[DysfunctionJunction time bomb]] of issues that is her adopted family, and ends with Panacea's incarceration and her sister becoming a [[AndIMustScream miserable pile of immobile flesh]].]]

* ''WesternAnimation/AdventureTime'':
** The Ice King continually interferes with Finn's attempt to prevent [[VileVillainSaccharineShow the Lich]] from reaching the Well of Power and regaining his full power. As a result the Lich, having regained his full power by the time Finn and Jake finally reach him, [[NoHoldsBarredBeatdown ends up jobbing Finn]] and destroying the Gauntlet, the one weapon that can hurt him, forcing Finn to find an alternative. Then the Ice King accidentally drops Bubblegum into the Well, which melts her and allows the Lich to possess her. After being frozen with help from the Ice King, she shatters, requiring medical attention to be put back together. Part of Bubblegum is missing though, causing her to come back as a 13-year old, which later results in [[RoyalBrat Earl of Lemongrab]] assuming the throne, if only for an episode.
*** The snail was responsible for the Lich breaking free in the first place. He just happened to have crawled into Finn's backpack right before Princess Bubblegum took Finn and Jake to the location of [[CrystalPrison the Lich's imprisonment]]. As soon as he crawled out, the snail, having no psychic protection, was mind controlled by the Lich into freeing him and setting the above chain of events into place, not to mention the ongoing threat of the Lich when [[spoiler:the Lich possesses the snail directly]].
** If it weren't for an unnamed Scandinavian dock worker selling an old crown to an antiquarian [[spoiler:by the name of Simon Petrikov]], the Ice King would never have existed. However, if that happened then [[spoiler:Marceline]] would have most likely died in the [[AfterTheEnd post-apocalyptic wasteland]], so it isn't all bad.
** In the AlternateUniverse [[FanNickname "Farmworld"]], the Destiny Gang terrorising Finn's village and his family leads to ''him'' wearing the Ice King's crown, which in turn leads to the release of the Lich and the world being inflicted with ''another'' apocalypse.
* ''WesternAnimation/AvatarTheLastAirbender'': The Earth King informed Azula (disguised as a Kyoshi Warrior) of the invasion of the Fire Nation. Cue next season where the invasion force finds all royalty in hiding, and the invasion ends in failure with almost all of them captured. Zuko hoped this would lead to his father re-thinking his strategy with the war. Unfortunately, it did, but it led to Ozai plotting genocide on the Earth Kingdom.
** During a war council, Zuko is asked how the people of the Earth Kingdom would react to occupation. He honestly replies that as long as they had their pride, they would never give into the Fire Nation. His statement led to Ozai plotting genocide on the Earth Kingdom.
* In the one episode of ''WesternAnimation/ComboNinos'' where [[NotMeThisTime neither Diadoro nor Gomez]] had released any Divinos, Principal Bronka accidentally released a Family of snake-like Divinos.
* In the ''WesternAnimation/FostersHomeForImaginaryFriends'' special WesternAnimation/DestinationImagination, Herriman {{inter|ruptedCooldownHug}}feres with a resolution between the Face and the rest of the main characters, Frankie included, by scolding him, causing him to go berserk. Unlike most other examples of this trope, he immediately comes to regret this.
* In ''WesternAnimation/TheJungleBunch'', Ernest the Kiwi's machines, which are usually created for some mundane task (one being a machine that dug chunks of ice out of a mountain and delivered the piece to Ernest's drink) often tend to become a danger to the jungle that The Jungle Bunch has to stop.
* ''WesternAnimation/{{Kaeloo}}'': Stumpy is one in the episode "Let's Play the Quest for the Wholly Gruel". [[spoiler: He finds the titular Wholly Gruel, a magic crayon which can make anything it draws real, and uses it to doodle all over some hieroglyphics in a cave depicting characters who resemble him and his friends. He draws a meteorite about to strike them, and his real friends, meanwhile, almost get hit by an actual meteorite.]]
* Everything that went wrong in the ''WesternAnimation/{{Kissyfur}}'' episode "The Birds And The Bears", from the cubs taking Gus' paddlecab for a spin which eventually leads them through dangerous rapids to the gators taking control of the paddlecab and using it to capture the cubs, all happened thanks to [[OneEpisodeWonder Donna's]] rebellious behavior. She even [[LaserGuidedKarma gets called out for it]] when she and some of the other cubs are captured by the gators.
--> '''[[JerkAss Lenny]]:''' [[JerkassHasAPoint It was]] ''[[JerkassHasAPoint your]]'' [[JerkassHasAPoint dumb idea to fool with the paddlecab, Donna!]]\\
'''Duane:''' Yeah, it definitely wasn't a cool thing to do!\\
'''[[TheEeyore Stuckey]]:''' Not cool at all!
* This often happens in ''WesternAnimation/MiraculousLadybug'' where a character picks up the JerkassBall and accidentally drives someone into enough despair to be corrupted by BigBad Hawk Moth. The undisputed queen of this trope is AlphaBitch Chloé Bourgeois, who has a body count in the double digits.
* In the season 6 premiere episode for ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', Flurry Heart destroys the Crystal Heart, the magical artifact that protects the Crystal Empire by keeping out the arctic climate of the rest of the region. This results in a massive blizzard that threatens to destroy the entire kingdom and either drive off or ''kill'' the inhabitants. The unwitting part is because she's a ''baby [[WingedUnicorn alicorn]]''; she didn't intend to destroy it, she didn't even have the cognizance to realize what was going on. Fortunately, the Crystal Heart gets repaired and in the process seems to have helped brought her own power under control.
** The episode "Rock Solid Friendship" reveals that [[spoiler:Maud Pie inadvertently helped Starlight Glimmer take over "Our Town" with her cutie mark removal spell by informing her of a stone that could contain the magic]].
* A strange example of a fictional character ending up being one for the real-life events. ''WesternAnimation/TheRenAndStimpyShow'' had the minor character George Liquor getting brutally beaten up by Ren in the episode "Man's Best Friend". Said scene was later one of the reasons for creator Creator/JohnKricfalusi's firing.
* The third ''WesternAnimation/RobotChicken'' ''Franchise/StarWars'' special has an unnamed man suggest that Palpatine go into politics, which of course eventually leads to him becoming Emperor, the galactic war, the forming of the Empire, and the destuction of the Jedi. Said man is seen thirty years later realizing that it was all his fault and preparing to commit suicide...at least until ''Series/WheelOfFortune'' comes on.
* Many a ''{{WesternAnimation/Rugrats}}'' episode's plot gets kicked off by the babies misunderstanding something they hear from the adults:
** "The Old Country" has Tommy overhearing Stu talk about trying to "keep out the elements" while staying in a cabin in the woods, and misunderstanding him to think that elephants are going to crush them all.
** "The Legend of Satchmo" has Grandpa spooking the babies with a story about Sasquatch, prompting them to run off and get lost in the garden.
** "Reptar on Ice" has Angelica talking about how the dinosaurs went extinct, prompting the babies to think that [[HesJustHiding Reptar must be in hiding]] and so they wander off to find him at the titular ice show.
** "The Dog Broomer" has Tommy again mishearing 'dog groomer' as 'dog broomer' and is convinced that the woman hired to groom Spike is going to kidnap him - causing all sorts of trouble for her.
** "Dummi Bear Dinner Disaster" has the babies scheming to ruin a dinner party when Susie fears she might have to move if it goes well (her father is just having a business colleague over").
** "When Wishes Come True" has Drew bringing a statue of Angelica to the house, with the babies fearing that Angelica has somehow been TakenForGranite. Of course the expensive statue ends up broken in their attempts to revive her.
* Homer from ''WesternAnimation/TheSimpsons'' does this at least once or twice a season. He's even responsible for the death of Maude Flanders; Homer tells a group of bimbos to aim their [[ItMakesSenseInContext 'Free t-shirt' bazookas]] at him, only to duck at the last possible second as he grabs something off the ground. The barrage of t-shirts knocks Maude over the edge of the stadium to her death in front of her ''husband and two young children''.
-->'''Homer:''' I'm the one whose antics drove her out of her seat. I'm the one who provoked the lethal barrage of t-shirts. [[RuleOfThree I'm the one]] who parked in the ambulance zone, preventing any possible resuscitation.
* ''WesternAnimation/SouthPark'':
** The "Imaginationland" Trilogy has the Evil Imaginary characters when they killed all the terrorists who caused the war, killing any chance of the Evil characters knowing that the terrorists framed the Good Imaginary characters for attacking the Evil ones, so that the war would continue until [[KillEmAll both sides killed each other]]. But this would have been averted if the Evil characters actually ''won'' the war. [[spoiler:Instead, with the help of [[BigGood Butters]], the Good characters won the war. Since the Evil characters already [[MoralEventHorizon destroyed any excuse of them being as much pawns as the Good characters]], Butters refused to resurrect any Evil casualties and [[CruelMercy the survivors were imprisoned]]. So instead of literal "doom," they get a FateWorseThanDeath.]]
* ''WesternAnimation/WildKratts'': Bumper the baby sperm whale, and/or his mother, tend to crop up at inconvenient times that cause more trouble than help. Although friendly enough to the Wild Kratts team, just having such large animals arrive unexpectedly has caused Aviva to crash her hoverbike in "Sea Otter Swim", and forced Chris to abandon his giant squid Power Mode in "Seasquatch" for fear that ''other'' (and hungry!) sperm whales may be hanging around the mother/calf pair.

[[folder:Real Life]]
* Creator/SamuelTaylorColeridge had a vivid dream, got up and started writing it down as the epic poem ''Kubla Khan'', [[http://sydneypadua.com/2dgoggles/the-person-from-porlock/ but then there was a knock at the door]], and a man from the nearby town of Porlock kept him talking just long enough to forget all about the dream and he never finished it. The [[http://en.wikipedia.org/wiki/Person_from_Porlock Person from Porlock]] is now literary shorthand for an unwanted visitor.
** Though some have theorized that Coleridge never intended to finish the poem (or that it was finished already), and he made up the story of the visitor just to mess with people. It doesn't help that Coleridge was a heavy opiate user, and the "dream" could have been something more of a "drug-induced vision," and the man from Porlock may or may not have actually been there. (Cue images of a poet standing on his doorstep talking to nobody while hazy visions of Kublai Khan's utopia dissipate into the aether.)
* UsefulNotes/ChristopherColumbus's voyages opened up the Americas to the Old World, bringing over disease which wiped out 90% of the Native Americans.
* Andy Dick. At a 1997 Christmas party, he reintroduced Brynn Omdahl, wife of Creator/PhilHartman, to cocaine, leading to his death. Which led to Andy Dick [[KickTheDog making some tasteless jokes about his role in Hartman's death,]] which resulted in Hartman's friend Creator/JonLovitz kicking his ass. It appears that Dick lives up to his name.
* Floyd Wells. He told fellow cons Perry Smith and Richard Hickock that a farmer he worked for named Herb Clutter kept a safe hidden with plenty of cash inside. As it turned out, there was no safe. It was this false info that led Smith and Hickock to massacre Mr. Clutter and his family, the basis for Creator/TrumanCapote's ''Literature/InColdBlood''.
* A rare inversion in [[http://en.wikipedia.org/wiki/Stanislav_Petrov Stanislav Petrov]]. While monitoring a satellite for the Soviet early warning system of a nuclear attack, he received a report of five inbound [=ICBMs=]. He decided it didn't make sense for a US first strike to be composed of only five nukes, he logged it as a technical error and overrode the command to launch a massive retaliation strike. Had he not been so cautious, WorldWarIII surely would have erupted.
* The failure of the Jay Leno Show on primetime had this effect on Creator/ConanOBrien's tenure as host of ''Series/TheTonightShow'', as it damaged local 11pm newscast ratings, as well as Conan himself, leading NBC to move Jay and his show back to his old 11:35 spot, and pushing Conan just past midnight. Conan, [[JudgmentOfSolomon not wanting to tarnish the legacy of the Tonight Show]], wanted no part of the agreement, and was subsequently evicted from the show, with Jay back as host.
* Senator Stephen Douglas, the man responsible for the Kansas-Nebraska Act. Originally, his intentions had simply been to get a railroad to California built, which would start in Chicago, Illinois (his home state). To do this, he proposed splitting the remaining unorganized chunk of the Louisiana Territory into the territories of Kansas and Nebraska. Pro-slavery Southerners slipped in a part saying that the legality of slavery in each territory would be decided by the voters there. But then pro-slavery advocates from Missouri flooded into Kansas to support slavery, resulting in "Bleeding Kansas", the prequel to UsefulNotes/TheAmericanCivilWar. Douglas himself has been branded pro-slavery for many years afterward following the fallout, with historians often leaving out that it was the South that suggested the decision of slavery by popular sovereignty and that Douglas himself simply wanted to build a railroad to California, obviously having no idea that the first planned transcontinental railroad would cause [[UsefulNotes/TheAmericanCivilWar the biggest schism ever to hit the United States]] over completely unrelated circumstances.
* In 2007, Creator/AdultSwim launched a guerrilla marketing campaign for the ''WesternAnimation/AquaTeenHungerForce'' [[TheMovie movie]] featuring battery-powered LED placards resembling the Mooninite characters being placed in numerous places around the US. However in Boston, police officials mistakenly thought that the [=LEDs=] were bombs, and treated the whole event as such. This event would turn out to known as the [[http://en.wikipedia.org/wiki/2007_Boston_bomb_scare Boston Bomb Scare]], which led to legal implications being placed on Turner Broadcasting and their contractors, the internet to make mock [[MemeticMutation "Never Forget" memes]], and forced then-current Creator/CartoonNetwork head Jim Samples to step down. It wouldn’t be long after until fans began to realize that Creator/CartoonNetwork would not be the same since the incident. Not because of any legal incidents, but because Sample’s replacement, Stuart Snyder, became the instigator of the channel’s infamous NetworkDecay, and an increase in Live action, and sitcom style shows.
* Franz von Papen, ex-Chancellor of the Weimar Republic, who in 1933 convinced President Hindenburg to make UsefulNotes/AdolfHitler chancellor in order to save his own political hide. By this point, the Nazis (forced by previous chancellors to fight repeated elections which sapped their funds) were rapidly losing support and were scraping the bottom of their piggy bank.
* Marinus van der Lubbe, the guy who started the Reichstag fire. He was a raving madman who was quickly captured that same night. It gave the Nazis the perfect opportunity to seize power, as the aforementioned repeated elections would eventually end in a loss of NSDAP seats.
* In the mid-'80s bribery scandal linked to R. Budd Dwyer (the inspiration behind "Hey Man, Nice Shot" by Music/{{Filter}}), William Smith, an attorney linked to the case, gave dubious testimony in order to accept a plea bargain, which made a guilty verdict for the former practically inevitable. As a result, Dwyer himself [[AteHisGun publicly committed suicide]] the day before the sentencing was to have taken place.
* In the night of April 14, 1912 Jack Phillips, radio operator of the ''RMS Titanic'', received a message alerting of an ice field ahead from the radio operator of the ''SS Californian'', Cyril Evans. The message interrupted an information directed to a first class passenger from Cape Race, Newfoundland, and Phillips radioed "Shut up, shut up! I am busy; I am working Cape Race!" back to Evans. Annoyed, Evans turned off the radio and went to sleep... ten minutes before the ''Titanic'' struck an iceberg. This prevented the ''Californian'' (who was the closest ship to the ''Titanic'') from hearing the ''Titanic'''s repeated distress calls and rescuing her passage before the ship went down.
* David Blair was originally slated to be Second Officer of the ''Titanic'' during her maiden voyage. However, in the last moment White Star reassigned the more experienced Henry Wilde, Chief Officer of the ''Olympic'' (at the time in drydock) to the ''Titanic'', and the knock-off effect was Blair being given another post out of the ship. By accident, Blair left with a key from the ''Titanic'', that turned out to be the only key to a safe in the Crow's Nest keeping the lookouts' binoculars. Without binoculars, the lookouts failed to see the iceberg in time.
* Jamie Gorelick, during her tenure as Deputy US Attorney General, was responsible for strengthening the restrictions on information sharing between domestic and foreign intelligence services. [[RightHandVersusLeftHand The lack of coordination]] this caused lead directly to the US government's failure to prevent the September 11th attacks, despite ample evidence of the plot, up to and including one of the terrorists being (briefly) taken into custody not long before it happened.
* Creator/SethRogen has become this with regards to the now-notorious consequences from ''Film/TheInterview'' and the cost it left Sony with. He knew that the film would piss off North Korea, and went ahead with it, presumably figuring that the DPRK would once again fail to follow up on its threats. However, he probably couldn't have seen his move as coming at the cost of the financial stability of the company he was working for, or The Guardians of Peace outright threatening terrorist attacks in theatres where it was due to play.
* On April 20, 2007, Davon Boddie was arrested for pot dealing outside of the Royal Suite nightclub in Roanoke, Virginia. Boddie was the cousin of [[UsefulNotes/AmericanFootball Atlanta Falcons quarterback]] Michael Vick, and gave Vick's home address as his own. Five days later, police searched the home and discovered a massive [[http://en.wikipedia.org/wiki/Bad_Newz_Kennels_dog_fighting_investigation dog-fighting ring]], leading to the arrest and conviction of Vick and four others.
* Gavrilo Princip and his co-conspirators in the assassination of Archduke Franz Ferdinand. All they wanted was a re-arrangement of some political borders in one part of the Balkans. What they got was a world-spanning war which was the deadliest in history, which led to the fall of the European colonial powers and the rise of communism, ''another'' world-spanning war 20 years later which became the new most deadliest war in history as a result of the mess the previous one left, and a subsequent cold war due to the results of the previous war that kept the world on the brink of destruction for fifty years. [[ArsonMurderAndJaywalking Oh, and that Balkan situation never was properly sorted out.]]
** To take it a step further, Ferdinand's driver, who was supposed to be taking him visit some people in the hospital, got lost, tried to reverse, and stalled the car almost exactly where Princip happened to be at that exact moment. Probably the most consequential wrong turn in human history.
* The TGWTG WebVideo/ToBoldlyFlee movie had a lot of effort and a lot of time put into it, but it was also a big TroubledProduction with many producers having bad memories of filming. As shown in the behind the scenes feature, things were apparently running smoothly until Rob Walker had the bright idea to lie about running fifteen minutes late. You can see Doug's face fall when he's told this, and according to [[WebVideo/TheNostalgiaChick Lindsay]] and [[WebVideo/ToddInTheShadows Todd]], that's when things started to break down.
* Best Buy's acquisition of Musicland in 2001 and their subsequent gross negligence, including making it ''[[EpicFail hemorrhage $80 million]]'' '''''[[EpicFail in one year]]''''' before selling it the following year, ultimately drove it to bankrupcy, leading to a mass closing of stores before being brought by Trans World Entertainment (owner of competitor FYE) in 2006. The mass closing of stores caused unsold stock to be taken back to the warehouses. While this has affected all home video companies, anime companies (who were 100% reliant on home video sales due to the lack of digital distribution rights at the time because [[ExecutiveMeddling the Japanese licensors refused to give them those rights]] as [[InsaneTrollLogic they equated legal digital distribution with piracy]]) were particularly severely affected, leading to the crash of the North American anime industry by the end of the 2000s, including the closures of Creator/{{ADV Films}}, Creator/{{Geneon}} and Creator/CentralParkMedia, and the downsizing and eventual closure of Creator/BandaiEntertainment. On the general side, the mass closing of the stores led to a decline of home video sales, which was further exacerbated by the growing ubiquity of streaming services such as Hulu and Netflix.
* Robert Campbeau's expansion into the United States resulted in the demise of the regional department store in the United States. To wit, Campbeau purchased Allied Stores and Federated Stores in the 1980s through junk bond [=LBOs=] but Campbeau was unable to pay it off. This, combined with a downturn in the retail industry at the time, has resulted in what many called the largest bankruptcy in U.S. history. This bankruptcy ultimately caused Macy's to start cannibalizing off stores that it inherited from both corporations beginning in the 1990s, and later on the May Department Stores company when that was merged into Macy's in 2005-2006.
* [[WesternTerrorists Dylann Storm Roof]], a white supremacist who took pictures of himself with Confederate memorabilia some time prior, shot up a church in Charleston with the hopes of dividing the nation. Not only did he [[EpicFail fail spectacularly]], he also caused collateral damage when his actions, which turned the general public (even in the South) against the Confederate flag, managed to TARFU ''Series/TheDukesOfHazzard''[='=]s reputation, if not outright FUBAR it.
* Roof's actions helped precipitate the rise of the alt-right, and subsequently the "Unite The Right" white supremacist rally at the University of Virginia in Charlottesville. Unfortunately for the alt-right, the rally caused a national crisis after one of the rallygoers mowed down a group of counterprotesters with his car, killing a young woman and injuring nineteen other people. The fallout from the attacks crippled the movement's momentum, with members losing jobs and being blacklisted from the internet. A nationwide sea change in attitudes about racism occurred, and the public began to turn against confederate imagery (as the Charlottesville protest was against the removal of a Robert E. Lee statue). The reputations of President Donald Trump and the Republican Party took a massive blow due to Trump's widely-panned response to the protest. The right's fight against antifa, the anti-fascist anarchist group who joined more peaceful counterprotesters to fight the white supremacists, was severely harpooned by the left's growing sympathy to the movement, as it was increasingly difficult to criticize a group, no matter how misguided, who fought on the same side as those killed in a terrorist attack. Most ironically, despite being called the "Unite the Right" rally, the aftermath rally ultimately divided the right and united the ''left''. Other organizations who got blamed for the rally include the ACLU, who defended the rights of the protesters, and the Charlottesville police, who did little to stop clashes between the two groups and thus failed to prevent the terrorist attack from occuring.
* The UsefulNotes/PunicWars was started by a band of mercenaries called the Mamertines who took over the city of Messana, and the Romans and the Carthaginians turn their attention away from them and then against each other over control of Sicily. What followed was years of bloody wars between the two empires, which finally ended with the destruction of Carthage.
* Faida Hamdi was a Tunisian government worker. In late 2010, she had a confrontation with a street vendor and confiscated the vendor's cart. The vendor [[SelfImmolation set himself in fire]] as a protest in front of a government building. His death [[UsefulNotes/TheArabSpring led to protests across the Middle East]] and the protests soon turned to devastating wars that would go on to shake the whole world. Today, Hamdi [[http://www.telegraph.co.uk/news/worldnews/africaandindianocean/tunisia/12054657/I-started-the-Arab-Spring.-Now-death-is-everywhere-and-extremism-blooming.html wonders]] WhatCouldHaveBeen if she did not have that initial confrontation.
* Michael Dukakis authorized weekend passes for prisoners while Governor of Massachusetts. One recipient of these weekend passes, Willie Horton, kidnapped, murdered, and raped one weekend. This ended up costing Dukakis the 1988 Presidential election after vice president George H.W. Bush's campaign pushed this heavily in an advertising campaign, and made politicians wary of being honest about their stances on crime, which led to the sudden toughening of criminal laws under Bill Clinton.
* Portuguese missionaries who threatened to conquer Japan through the forced spread of Christianity were directly responsible for centuries of de jure xenophobia in the country, which only started to be loosened (key word: started, only in 2017 did discrimination against foreigners living in the country start to significantly fade in earnest) when Matthew Perry opened trade routes between the United States and Japan in the middle of the 19th century via GunboatDiplomacy.
* The good people of Spain probably had no idea they were making world history beyond the scope of their own country when they toppled Isabela III in 1868. As even many of the revolutionaries did not even think of a Republic as a possible solution, they searched Europe for a potential King (or perhaps Queen). In the course of this search, they also contacted [[https://en.wikipedia.org/wiki/Leopold,_Prince_of_Hohenzollern Leopold of Hohenzollern]], a good Catholic, a family man in his mid thirties who seemed altogether a good candidate for the Spanish throne by the standards of the time. There was only one problem: as you might have guessed from his name, he was a (distant) relative of the Hohenzollern dynasty in Prussia and French emperor Napoleon III feared having German speaking kings in his east and west, so Leopold ultimately declined. This could have been the end of it, and indeed in most cases it would have, but Napoleon III being Napoleon III, he was not content with Leopold himself refusing, he wanted the Prussian king to renounce any claim of any Hohenzollern to the Spanish throne now and in the future. In 1870 the French ambassador bothered the Prussian King Wilhelm at a health spa in Bad Ems where the emperor was enjoying a ''Kur''[[note]]Basically a holiday that is supposed to cure ailments, still popular with Germans today[[/note]] and while the French ambassador was rude, the king was cordial and polite but basically told him "We've talked about this before, Leopold has already rejected, I am not him and I can't give promises for what my heirs might do". Unsatisfied, the French ambassador tried to bother the Prussian King again but the Prussian King in essence had a high ranking nobleman (sending anybody less would have been an affront) tell the French ambassador essentially the same thing again and that further discussing the issue was obviously pointless, the facts being what they were. Wilhelm then sent a report about those events in a telegram to his Prime Minister Otto von Bismarck. Bismarck saw an opportunity there and had the telegram shortened so that it could be read as the Prussian King rudely refusing to even meet with the ambassador (which would be diplomacy talk for "shove it up your ***") and to add insult to injury having that message delivered through some page. While Bismarck did ''not'' as he was often accused of QuoteMine the telegram, the French press published the shortened version and the reaction Bismarck intended occurred. France was furious, the emperor wanted to secure his domestic position threatened by previous foreign policy blunders[[labelnote:examples]]Like supporting Austria in the Austro-Prussian war but not actually intervening, which resulted in military loss for Austria, being outmaneuvered in the Italian wars of independence which France won for the Italians in large part but had nothing to show for except Nice or the disaster that was the Mexican Expedition which installed the brother of Austrian Emperor Franz Joseph as emperor only to have the Mexican Emperor turn rogue and end in front of a Mexican firing squad[[/labelnote]] as well as increasing demands for political liberalization and thus an ill-prepared France launched a war over what was seen by virtually everybody in Europe as a nothing-burger. France had hoped to beat Prussia and maybe call some allies to their side if the fight took longer. Not only did nobody ally with France, but all German states except Austria (which stayed neutral) rallied to the Prussian cause to fulfill secret defensive treaties. And then Napoleon III was captured near Sedan. While the newly declared Third Republic fought on, Prussia utterly wiped the floor with the French Army and ultimately France had to accept a humiliating peace treaty, that cost her five billion Francs in gold, Alsace and Lorraine and an immensurable sum in clout, credibility and respect around the world. To add insult to injury, a new German Empire was declared ''in Versailles''. This slight of course caused desire on the French part for revenge, which became one of the ultimate causes for UsefulNotes/WorldWarI which the Germans lost, causing desire for revenge in them, ultimately leading to UsefulNotes/WorldWarII. Thanks for asking about that Royal Succession thing, Spain.
* On July 1st, 2002, Swiss air traffic controller Peter Nielsen, overworked and under-equipped, spotted two planes on a collision course and ordered one of them to descend. Unfortunately, due to his workload and the fact that key pieces of his system were offline, he failed to realize that the other plane was already descending in compliance with an automated collision avoidance system, and that instead of moving the first plane ''out'' of the second plane's path, he was instead ensuring they remained ''in'' it. Predictably, the two planes collided, killing everyone on board both flights. ([[RoaringRampageOfRevenge Nielsen himself was later murdered in an act of vengeance by a man whose entire family had died in the disaster.]])
* One fateful day in 1921, a random black man in Tulsa stepped into an elevator operated by a white girl. To this day, the events of what really happened remain unknown, but regardless, the incident set off a chain reaction leading to the destruction of Greenwood Avenue.
* A barbecue held by Bruce Pearl, then-head coach of the Tennessee Volunteers basketball team, only fueled the fire of Fulmer's Revenge and ensured that it could not only not be put out on the football side, where it had originated, as soon as then-head coach Derek Dooley would've liked, it also cost Dooley his job, spread to the rest of UT athletics, and became a major wildfire, as it were. What's worse is that [[ArsonMurderAndJaywalking Pearl's successor, Cuonzo Martin, never really got to show off his true potential as a UT basketball coach in the three seasons he was with UT before he resigned to coach the California Golden Bears]]. Read all the sordid details [[https://allfortennessee.com/2018/07/13/tennessee-vols-13-unlucky/5/ here]],[[https://allfortennessee.com/2018/07/13/tennessee-vols-13-unlucky/6/ here]], and [[https://allfortennessee.com/2018/07/13/tennessee-vols-13-unlucky/10/ here]].

to:

** [[spoiler:Otome and Makoto]] might be even worse ones in some routes. It's depending on Makoto pulling one or another action that [[spoiler:Otome will or not tell Makoto's best friend Taisuke that girls like forceful dudes during sex -- which will lead him to rape his crush Kotonoha, under the very stupid belief that the poor girl's barely whispered "no, don't..." are actually a part of the "protest pretend" kink. [[note]]where the passive partner in hentai/ecchi/hard yaoi/etc. media fakes being embarrassment and unwillingness.[[/note]].]]
** Also, [[spoiler: Nanami, Hikari and Otome's GirlPosse]] can become the trope, when [[spoiler: they '''horribly''' bully Kotonoha to [[ShippingTorpedo keep her away from Makoto]] [[ShipperOnDeck and make sure Sekai gets him]].]] This can either lead to [[spoiler: Makoto ''completely cutting Sekai off his life'' before choosing Kotonoha since he thinks she's the one instigating the bullying that Koto has been a victim of [[note]](she's almost surely '''not''', but Makoto is simply too angry to consider that because school bullying is his BerserkButton)[[/note]] ]] or to [[spoiler: Kotonoha [[GoMadFromtheRevelation breaking down so badly]] for said harrassment that ''she murders Sekai in broad daylight''.]] In either way, their support to one girl over the other ''makes things MUCH worse for the one they wanted to "help"''.
* ''VisualNovel/UminekoWhenTheyCry'':
** [[spoiler:Battler Ushiromiya]] of all people, who drives [[spoiler:Sayo Yasuda]] to orchestrate the murders [[spoiler:by unwittingly breaking a promise to take them away from Rokkenjima]]. Battler didn't come back for it because of ''very'' serious family issues (depicted below), but unfortunately, [[spoiler:the already broken Sayo]] took this very, ''very'' badly.
** Furthermore, if that's the case, then [[spoiler: ''Rudolf and Kyrie'']] are also responsible. [[spoiler: Had they not [[ParentWithNewParamour married too soon after the death of Battler's beloved mother]] for the teenage Battler's taste, he would have not broken ties with his paternal family. Therefore, he would've showed up in Rokkenjima sooner and/or more frequently and, as the GuileHero he is, he would've found a way to help poor Sayo deal with their crappy situation, promise or not.]]
** There's also [[spoiler:Natsuhi]], who is largely responsible for [[spoiler:Sayo Yasuda]]'s issues in the first place. [[spoiler:Sayo was pretty much forcibly given to her by Kinzo as a baby to raise after she couldn't give birth to an heir, which [[GoodIsOldFashioned the very traditional Natsuhi]] saw as a reminder of her "failure" as a woman. One day, out of anger and resentment out of having to raise a child that wasn't her own, Natsuhi completely lost it and pushed a servant holding the baby off a cliff. The servant died but the baby survived, though with injuries that damaged their sexual organs, leading to Sayo having major gender/body issues later in life, which would ''not'' exactly help with their increasingly unstable mental state. An alternate continuity shows that, had Natsuhi not snapped the way she did, Sayo would grow into the [[TheAce far more stable]] [[AlternateSelf Lion Ushiromiya]].]]
* In ''VisualNovel/ZeroTimeDilemma'', Zero mentions a story of how a ''snail'' caused 6 deaths by just being where it was. A woman [[spoiler: heavily hinted to be Eric's mother]] used a different way than usual because a snail was on the usual one. This caused her to meet a young SerialKiller, [[spoiler: who turns out to be Mira]], and get killed. An innocent man [[spoiler: later revealed to be Akane's father]] was caught and sentenced to death, which lead to his wife to commit suicide. The man was going to catch a taxi but he couldn't, and the taxi driver took a surgeon going to operate a kid. The taxi had an accident and both the driver and the surgeon died. Since the kid never received his surgery, he died as well. [[ArcWords Life is simply unfair]]

* In ''WebAnimation/DeathBattle'', [[WesternAnimation/HeManAndTheMastersOfTheUniverse1983 He-Man]] ended up as this during his fight against [[WesternAnimation/ThunderCats Lion-O]]. He just wanted to fend off Lion-O, but in doing so, [[spoiler:he crushed the Eye of Thundera, which kept the Thunderan race alive.]]
* ''WebAnimation/LlamasWithHats'': In episode 7, Paul [[spoiler:severs all ties with the series' AxCrazy VillainProtagonist Carl]], as any sane person would and should. However, it turns out that [[spoiler:Paul's friendship was the only thing keeping Carl a little bit sane (a very, ''very'' little bit), and without Paul around, Carl ends up destroying all life on Earth.]]
* In ''Machinima/RedVsBlue'':
** It's revealed in season 10 that [[spoiler:Carolina]]'s pride was responsible for nearly everything bad that happened to the Freelancers--[[spoiler:her original AI was Sigma, but she gave him up to Maine. Sigma and Maine went on to become the Meta and kill several other Freelancers. When she finally did get an AI, she took ''two'': the ones that were originally meant for Wash and South. South's jealousy due to her brother North getting an AI and her not led to South leaving North to die and shooting Wash in the back, and her own death at Wash's hands later. Wash, on the other hand, did get an AI... Epsilon. Which led to him going insane and plotting to take down the Director of Project Freelancer for his crimes.]] All because of pride.
** There's [[spoiler:the Director's obsession with his dead love, Allison. When the Alpha AI, copied from the Director's mind, was created, the Beta AI (based on the Director's memories of Allison) naturally fragmented from it. This inspired the Director to torture the Alpha into making more fragments, the ones mentioned above, to figure out a way to "get her right".]]
** There is also [[spoiler:the Sleeveless Insurrectionist Soldier, who shot Agent Maine in the throat several times, rendering him mute. This gave Carolina an excuse to give her A.I. Sigma away so that Maine could have an alternate way to speak. This contributed into forever turning him into the Meta.]]
** Season 14 ultimately reveals that [[spoiler:everything happened because Agent Florida tripped over a wire and broke it. Originally, had something happened to him, other Freelancers were to show up and take his place, starting with Agent California. However, by damaging the wire, the list of Freelancers were replaced by five other names, starting with Caboose. Thus, because of a damaged wire, Agent Florida would kick off a series of events that would lead to the destruction of the Freelancer Project.]]
* ''WebAnimation/{{RWBY}}'': During the Volume 6 Character Short, Ghira is troubled by [[MurderIsTheBestSolution Adam's]] violence and objects to him killing humans in front of him. [[WellIntentionedExtremist Sienna]] defends Adam, pointing out that he just saved Ghira's life. After having seen him fight and gone on several missions with him, she gives him control of the Vale branch of the [[WesternTerrorists White Fang]], praising his abilities and telling him that if he continues on the path he's on, he'll end up sitting by her side on the High Leader's throne. [[spoiler:What she [[UnwittingInstigatorOfDoom doesn't realise]] at that time, is that [[ANaziByAnyOtherName his path]] is not the one she thinks it is, and that [[GoneHorriblyRight it leads]] to him murdering her in Volume 5, [[KlingonPromotion usurping her throne]] and leading the militant White Fang that she created falling to a [[FantasticGhetto Menagerie army]] and the Mistral Police Force, thereby reinvigorating [[GentleGiant Ghira]], the peaceful leader she [[CategoryTraitor disapproved of and deposed]], into resuming control of the White Fang in order to create a brand new peaceful protest group.]]

* In the ComicBook/ChickTract "Fatal Decision", Brutus, an orderly on the brink of being fired for rudeness to patients, makes hints that John shouldn't trust Dr. Bowers, leading to John destroying the vaccine and dying of his disease.
** The devils often invoke this trope, choosing someone who has an incidental relationship to the person whose soul they want to claim. In "The Assignment" they succeed in convincing Charles Bishop's subordinate's wife to badger him out of witnessing to his boss. They try to distract Cathy with a boy, only for it to fail when he proves to be a JerkAss, and try to have the previously mentioned subordinate call Bishop with a sales proposition, only for the angels to thwart this attempt twice. Charles ultimately dies in his sins, making the first example a successful one.
* In ''Webcomic/{{Freefall}}'', Florence has suspicions that Maxwell Post might be this when she learns that he is the spiritual advisor to the [[AIIsACrapshoot sapient robot]] population. [[SubvertedTrope So far, his efforts have been among the least of her worries.]]
* One ''Webcomic/ElGoonishShive'' storyline featured a rampaging boar which was enchanted to grow to an enormous size. Said enchantment is heavily implied to have come from [[spoiler:Rhoda]], who was unwittingly given a [[PowerTattoo magic mark]] and unknowingly used it on the boar while in a state of panic.
* Virtually everyone in ''Webcomic/{{Homestuck}}''; the ''single'' good character who doesn't manage this is Nepeta[[note]]largely because she's never shown actually ''doing'' much of anything; the one time she tries to do something significant she's hopelessly outclassed and dies pointlessly and almost immediately[[/note]].
** Tavros deserves special mention. At one point he attempts to save a young Jade from accidentally shooting herself by taking psychic control of her dog, Becquerel, and deflecting the shot at her grandfather (whom he believed was a hostile intruder), killing him. He then points out that Becquerel would have saved her even if he hadn't done anything (in a way that would not have killed Grandpa Harley) and that he only interfered so he could feel a little better about himself. Even when she points out that killing her grandfather was ''not'' appreciated, he still thinks he made the right choice.
* In ''Webcomic/KevinAndKell'', [[Webcomic/GeneralProtectionFault Nick and Ki's]] [[{{Crossover}} arrival in Domain]] by way of interdimensional travel disrupts the balance between the animal- and human-dominated worlds to the point at which the other two humans living on the animal side [[spoiler:Lindesfarne and Danielle]] are forced to leave lest the world suffer instinct loss. [[spoiler:Luckily, Catherine and Nigel do it instead]].
* In ''Webcomic/KidRadd'', two Moderators are given a large sum of money in order to hire an assassin to kill Radd, as Captain QB can't be directly implicated in illegal activities and needs to use a proxy. They reason that it can't be hard to kill someone in jail (as Radd is being imprisoned for illegally entering other games), and hire Kobayashi the discount ninja so that they can pocket the rest of the money. Radd survives the assassination attempt and Kobayashi becomes a recurring character who later meets up with Gnarl and, while training together, stumbles upon [[spoiler:Chimera Point, the keystone to Crystal's plans, which eventually results in ''her'' finding it too]].
* Several characters in ''Webcomic/{{minus}}'' take actions that, unbeknownst to them, lead to TheEndOfTheWorldAsWeKnowIt. First, a mysterious man pretty much "breaks" [[RealityWarper minus]] by stuffing her into a briefcase. She is freed, but becomes a CloudCuckooLander. In an attempt to cure her, the green-haired girl throws a rock at minus's head, causing her [[spoiler:[[LiterallyShatteredLives to shatter]]]]. Because she is now [[spoiler:a ghost]], minus starts to spend more time with her ghost friends than her live ones. Which leads to the biggest example of this trope in the comic: the red-haired ghost asks minus to bring her back to life, because she has some UnfinishedBusiness with certain humans that the readers don't get to see. minus agrees. Unfortunately, once the other ghosts find out, they demand that minus revive them too. She does, [[spoiler:only for the sheer influx of bodies on Earth to suffocate every living thing on the planet, including those who were just revived]]. [[SpaceWhaleAesop And that is why you should never ask anything of an omnipotent being, ever.]]
* In ''Webcomic/NobodyScores'' this is frequently the role of [[Main/{{CloudCuckoolander}} Jane Doe]]. [[http://nobodyscores.loosenutstudio.com/index.php?id=488 This]] for example.
* ''Webcomic/TheOrderOfTheStick'':
** [[KnightTemplar Miko Miyazaki]], having already [[DePower lost her Paladin abilities]] through the [[TheKingslayer unwarranted execution of of Lord Shojo]], ends up destroying the [[MacGuffin Sapphire Gate]], having once again misinterpreted what the gods wanted of her. Had she not been so hasty in doing this, the ghost of [[PrecursorHeroes Soon Kim]] could have permanently ended the threat of [[BigBad Xykon]] and [[DragonWithAnAgenda Redcloak]], who, themselves, were aiming for the gate, anyway.
** Right-Eye had the idea to recruit Xykon. If not for that one moment, Xykon never would have learned about the Snarl, probably never would have had the brains to become a lich on his own and would have continued his life of petty evil until he died and went to the Lower Planes without ever becoming the apocalyptic threat he is today.
** When Vaarsuvius went on a RoaringRampageOfRevenge and [[spoiler:cast Familicide, killing every creature related to the Ancient Black Dragon]], they didn't have any intentions beyond protecting their own family (and maybe enjoying the wildly DisproportionateRetribution way too much). Unfortunately for them, and also the world, [[spoiler:the Draketooth family guarding one of the Gates has a MeaningfulName, and Familicide wiped out every last one of them, leaving the Gate completely unprotected.]]

* Trouble in ''Roleplay/DinoAttackRPG'', being a mutant lizard who was adopted and trained by a member of the team trying to eradicate his kind, was the first to spark the tension between realist and idealist members of the team. Technically speaking he is responsible both for the campaigns by both Kotua ''and'' Cam O'Cozy, both of whom tried to commit genocide against idealist agents.
* ''WebVideo/DontHugMeImScared'':
** [[spoiler:Red Guy]] is heavily implied to be this in the fifth episode. At the beginning of the episode, Duck Guy and Yellow Guy note that something's "missing", unaware that it's [[spoiler:their friend Red Guy.]] Near the beginning of the episode, a phone rings, and when Duck Guy answers, he's suddenly in an operating room, watching himself on the television, with a mysterious voice saying "you have to know right from wrong". This seems to lead him to realize that the lesson would go wrong somehow and try to escape, [[spoiler:for which he is EatenAlive.]] The end credits imply that [[spoiler:the call was made by Red Guy, who somehow escaped from the lessons and was trying to help his friends escape, and hearing Red Guy's voice was what made Duck Guy realize what was going on. If it weren't for Red Guy, Duck Guy would probably still be alive, and Yellow Guy wouldn't be completely alone.]]
** The sixth video takes this further by implying that [[spoiler:Red Guy is [[GainaxEnding somehow]] inadvertently causing the GroundhogDayLoop the puppets are trapped in.]]
* ''Series/{{Noob}}'':
** In late Season 4, Kary commits the InnocentlyInsensitive act of [[spoiler:choosing to check out an in-game event over finishing her (in-game) wedding to Arthéon, who was taking it much more serously than she was.]] Arthéon was so furious that he went on a RoaringRampageOfRevenge. Even after he calmed down, he still had a much more cynical view of everyone and everything he knew than before. This became a really bad thing [[spoiler:because Arthéon eventually got a job that enabled him to impact the game's plot and the story has reached a point where he will be responsible for the game world's destruction unless his former guildmates stop him]].
** In late Season 5, Roxana keeps Saphir from doing a quest that impacts the game story and may have the side a effect of making Saphir's guild outrank Roxana's once it's done. The reason the quest could have been singlehandedly enough to significantly uprank Saphir's guild? It would bring a big blow to the BigBad if accomplished, help make him stronger if failed.
* In ''Wiki/SCPFoundation'', [[http://www.scp-wiki.net/scp-1867 SCP-1867 ("A Gentleman")]] is Lord Blackwood, an adventurous seaslug who appears in many other works telling about his adventurous times. If the accounts are correct, Lord Blackwood may have just been the one that [[spoiler: inspired SCP-319's maker to try and travel to another universe, and gave him the means to attempt it]]. A short read of that particular file lets us know that attempt essentially ''doomed this universe''.
* ''Literature/TheTimTebowCFLChronicles:'' Tim Tebow unintentionally destroys Canadian football. Unknown to him, the rest of the league can't start the 2014 playoffs until they get the results from his game against the REDBLACKS. But with Tebow leading the Argos' offense, and with [[{{Calvinball}} the utterly bizarre rules of "bound-for-street" play]], the game lasts ''over a decade''--while every other team can't do anything but wait.
* In ''Literature/{{Worm}}'', the Undersider's local [[TheSmartGuy Smart Girl]], Tattletale, normally isn't this, but a character flaw of hers is to start throwing everything her SherlockScan superpower picks up everywhere when she panics. This doesn't really hurt anyone...with the rather glaring exception of [[spoiler:cluing [[TheMedic Panacea]] into her family history...which sets off the [[DysfunctionJunction time bomb]] of issues that is her adopted family, and ends with Panacea's incarceration and her sister becoming a [[AndIMustScream miserable pile of immobile flesh]].]]

* ''WesternAnimation/AdventureTime'':
** The Ice King continually interferes with Finn's attempt to prevent [[VileVillainSaccharineShow the Lich]] from reaching the Well of Power and regaining his full power. As a result the Lich, having regained his full power by the time Finn and Jake finally reach him, [[NoHoldsBarredBeatdown ends up jobbing Finn]] and destroying the Gauntlet, the one weapon that can hurt him, forcing Finn to find an alternative. Then the Ice King accidentally drops Bubblegum into the Well, which melts her and allows the Lich to possess her. After being frozen with help from the Ice King, she shatters, requiring medical attention to be put back together. Part of Bubblegum is missing though, causing her to come back as a 13-year old, which later results in [[RoyalBrat Earl of Lemongrab]] assuming the throne, if only for an episode.
*** The snail was responsible for the Lich breaking free in the first place. He just happened to have crawled into Finn's backpack right before Princess Bubblegum took Finn and Jake to the location of [[CrystalPrison the Lich's imprisonment]]. As soon as he crawled out, the snail, having no psychic protection, was mind controlled by the Lich into freeing him and setting the above chain of events into place, not to mention the ongoing threat of the Lich when [[spoiler:the Lich possesses the snail directly]].
** If it weren't for an unnamed Scandinavian dock worker selling an old crown to an antiquarian [[spoiler:by the name of Simon Petrikov]], the Ice King would never have existed. However, if that happened then [[spoiler:Marceline]] would have most likely died in the [[AfterTheEnd post-apocalyptic wasteland]], so it isn't all bad.
** In the AlternateUniverse [[FanNickname "Farmworld"]], the Destiny Gang terrorising Finn's village and his family leads to ''him'' wearing the Ice King's crown, which in turn leads to the release of the Lich and the world being inflicted with ''another'' apocalypse.
* ''WesternAnimation/AvatarTheLastAirbender'': The Earth King informed Azula (disguised as a Kyoshi Warrior) of the invasion of the Fire Nation. Cue next season where the invasion force finds all royalty in hiding, and the invasion ends in failure with almost all of them captured. Zuko hoped this would lead to his father re-thinking his strategy with the war. Unfortunately, it did, but it led to Ozai plotting genocide on the Earth Kingdom.
** During a war council, Zuko is asked how the people of the Earth Kingdom would react to occupation. He honestly replies that as long as they had their pride, they would never give into the Fire Nation. His statement led to Ozai plotting genocide on the Earth Kingdom.
* In the one episode of ''WesternAnimation/ComboNinos'' where [[NotMeThisTime neither Diadoro nor Gomez]] had released any Divinos, Principal Bronka accidentally released a Family of snake-like Divinos.
* In the ''WesternAnimation/FostersHomeForImaginaryFriends'' special WesternAnimation/DestinationImagination, Herriman {{inter|ruptedCooldownHug}}feres with a resolution between the Face and the rest of the main characters, Frankie included, by scolding him, causing him to go berserk. Unlike most other examples of this trope, he immediately comes to regret this.
* In ''WesternAnimation/TheJungleBunch'', Ernest the Kiwi's machines, which are usually created for some mundane task (one being a machine that dug chunks of ice out of a mountain and delivered the piece to Ernest's drink) often tend to become a danger to the jungle that The Jungle Bunch has to stop.
* ''WesternAnimation/{{Kaeloo}}'': Stumpy is one in the episode "Let's Play the Quest for the Wholly Gruel". [[spoiler: He finds the titular Wholly Gruel, a magic crayon which can make anything it draws real, and uses it to doodle all over some hieroglyphics in a cave depicting characters who resemble him and his friends. He draws a meteorite about to strike them, and his real friends, meanwhile, almost get hit by an actual meteorite.]]
* Everything that went wrong in the ''WesternAnimation/{{Kissyfur}}'' episode "The Birds And The Bears", from the cubs taking Gus' paddlecab for a spin which eventually leads them through dangerous rapids to the gators taking control of the paddlecab and using it to capture the cubs, all happened thanks to [[OneEpisodeWonder Donna's]] rebellious behavior. She even [[LaserGuidedKarma gets called out for it]] when she and some of the other cubs are captured by the gators.
--> '''[[JerkAss Lenny]]:''' [[JerkassHasAPoint It was]] ''[[JerkassHasAPoint your]]'' [[JerkassHasAPoint dumb idea to fool with the paddlecab, Donna!]]\\
'''Duane:''' Yeah, it definitely wasn't a cool thing to do!\\
'''[[TheEeyore Stuckey]]:''' Not cool at all!
* This often happens in ''WesternAnimation/MiraculousLadybug'' where a character picks up the JerkassBall and accidentally drives someone into enough despair to be corrupted by BigBad Hawk Moth. The undisputed queen of this trope is AlphaBitch Chloé Bourgeois, who has a body count in the double digits.
* In the season 6 premiere episode for ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', Flurry Heart destroys the Crystal Heart, the magical artifact that protects the Crystal Empire by keeping out the arctic climate of the rest of the region. This results in a massive blizzard that threatens to destroy the entire kingdom and either drive off or ''kill'' the inhabitants. The unwitting part is because she's a ''baby [[WingedUnicorn alicorn]]''; she didn't intend to destroy it, she didn't even have the cognizance to realize what was going on. Fortunately, the Crystal Heart gets repaired and in the process seems to have helped brought her own power under control.
** The episode "Rock Solid Friendship" reveals that [[spoiler:Maud Pie inadvertently helped Starlight Glimmer take over "Our Town" with her cutie mark removal spell by informing her of a stone that could contain the magic]].
* A strange example of a fictional character ending up being one for the real-life events. ''WesternAnimation/TheRenAndStimpyShow'' had the minor character George Liquor getting brutally beaten up by Ren in the episode "Man's Best Friend". Said scene was later one of the reasons for creator Creator/JohnKricfalusi's firing.
* The third ''WesternAnimation/RobotChicken'' ''Franchise/StarWars'' special has an unnamed man suggest that Palpatine go into politics, which of course eventually leads to him becoming Emperor, the galactic war, the forming of the Empire, and the destuction of the Jedi. Said man is seen thirty years later realizing that it was all his fault and preparing to commit suicide...at least until ''Series/WheelOfFortune'' comes on.
* Many a ''{{WesternAnimation/Rugrats}}'' episode's plot gets kicked off by the babies misunderstanding something they hear from the adults:
** "The Old Country" has Tommy overhearing Stu talk about trying to "keep out the elements" while staying in a cabin in the woods, and misunderstanding him to think that elephants are going to crush them all.
** "The Legend of Satchmo" has Grandpa spooking the babies with a story about Sasquatch, prompting them to run off and get lost in the garden.
** "Reptar on Ice" has Angelica talking about how the dinosaurs went extinct, prompting the babies to think that [[HesJustHiding Reptar must be in hiding]] and so they wander off to find him at the titular ice show.
** "The Dog Broomer" has Tommy again mishearing 'dog groomer' as 'dog broomer' and is convinced that the woman hired to groom Spike is going to kidnap him - causing all sorts of trouble for her.
** "Dummi Bear Dinner Disaster" has the babies scheming to ruin a dinner party when Susie fears she might have to move if it goes well (her father is just having a business colleague over").
** "When Wishes Come True" has Drew bringing a statue of Angelica to the house, with the babies fearing that Angelica has somehow been TakenForGranite. Of course the expensive statue ends up broken in their attempts to revive her.
* Homer from ''WesternAnimation/TheSimpsons'' does this at least once or twice a season. He's even responsible for the death of Maude Flanders; Homer tells a group of bimbos to aim their [[ItMakesSenseInContext 'Free t-shirt' bazookas]] at him, only to duck at the last possible second as he grabs something off the ground. The barrage of t-shirts knocks Maude over the edge of the stadium to her death in front of her ''husband and two young children''.
-->'''Homer:''' I'm the one whose antics drove her out of her seat. I'm the one who provoked the lethal barrage of t-shirts. [[RuleOfThree I'm the one]] who parked in the ambulance zone, preventing any possible resuscitation.
* ''WesternAnimation/SouthPark'':
** The "Imaginationland" Trilogy has the Evil Imaginary characters when they killed all the terrorists who caused the war, killing any chance of the Evil characters knowing that the terrorists framed the Good Imaginary characters for attacking the Evil ones, so that the war would continue until [[KillEmAll both sides killed each other]]. But this would have been averted if the Evil characters actually ''won'' the war. [[spoiler:Instead, with the help of [[BigGood Butters]], the Good characters won the war. Since the Evil characters already [[MoralEventHorizon destroyed any excuse of them being as much pawns as the Good characters]], Butters refused to resurrect any Evil casualties and [[CruelMercy the survivors were imprisoned]]. So instead of literal "doom," they get a FateWorseThanDeath.]]
* ''WesternAnimation/WildKratts'': Bumper the baby sperm whale, and/or his mother, tend to crop up at inconvenient times that cause more trouble than help. Although friendly enough to the Wild Kratts team, just having such large animals arrive unexpectedly has caused Aviva to crash her hoverbike in "Sea Otter Swim", and forced Chris to abandon his giant squid Power Mode in "Seasquatch" for fear that ''other'' (and hungry!) sperm whales may be hanging around the mother/calf pair.

* Creator/SamuelTaylorColeridge had a vivid dream, got up and started writing it down as the epic poem ''Kubla Khan'', [[http://sydneypadua.com/2dgoggles/the-person-from-porlock/ but then there was a knock at the door]], and a man from the nearby town of Porlock kept him talking just long enough to forget all about the dream and he never finished it. The [[http://en.wikipedia.org/wiki/Person_from_Porlock Person from Porlock]] is now literary shorthand for an unwanted visitor.
** Though some have theorized that Coleridge never intended to finish the poem (or that it was finished already), and he made up the story of the visitor just to mess with people. It doesn't help that Coleridge was a heavy opiate user, and the "dream" could have been something more of a "drug-induced vision," and the man from Porlock may or may not have actually been there. (Cue images of a poet standing on his doorstep talking to nobody while hazy visions of Kublai Khan's utopia dissipate into the aether.)
* UsefulNotes/ChristopherColumbus's voyages opened up the Americas to the Old World, bringing over disease which wiped out 90% of the Native Americans.
* Andy Dick. At a 1997 Christmas party, he reintroduced Brynn Omdahl, wife of Creator/PhilHartman, to cocaine, leading to his death. Which led to Andy Dick [[KickTheDog making some tasteless jokes about his role in Hartman's death,]] which resulted in Hartman's friend Creator/JonLovitz kicking his ass. It appears that Dick lives up to his name.
* Floyd Wells. He told fellow cons Perry Smith and Richard Hickock that a farmer he worked for named Herb Clutter kept a safe hidden with plenty of cash inside. As it turned out, there was no safe. It was this false info that led Smith and Hickock to massacre Mr. Clutter and his family, the basis for Creator/TrumanCapote's ''Literature/InColdBlood''.
* A rare inversion in [[http://en.wikipedia.org/wiki/Stanislav_Petrov Stanislav Petrov]]. While monitoring a satellite for the Soviet early warning system of a nuclear attack, he received a report of five inbound [=ICBMs=]. He decided it didn't make sense for a US first strike to be composed of only five nukes, he logged it as a technical error and overrode the command to launch a massive retaliation strike. Had he not been so cautious, WorldWarIII surely would have erupted.
* The failure of the Jay Leno Show on primetime had this effect on Creator/ConanOBrien's tenure as host of ''Series/TheTonightShow'', as it damaged local 11pm newscast ratings, as well as Conan himself, leading NBC to move Jay and his show back to his old 11:35 spot, and pushing Conan just past midnight. Conan, [[JudgmentOfSolomon not wanting to tarnish the legacy of the Tonight Show]], wanted no part of the agreement, and was subsequently evicted from the show, with Jay back as host.
* Senator Stephen Douglas, the man responsible for the Kansas-Nebraska Act. Originally, his intentions had simply been to get a railroad to California built, which would start in Chicago, Illinois (his home state). To do this, he proposed splitting the remaining unorganized chunk of the Louisiana Territory into the territories of Kansas and Nebraska. Pro-slavery Southerners slipped in a part saying that the legality of slavery in each territory would be decided by the voters there. But then pro-slavery advocates from Missouri flooded into Kansas to support slavery, resulting in "Bleeding Kansas", the prequel to UsefulNotes/TheAmericanCivilWar. Douglas himself has been branded pro-slavery for many years afterward following the fallout, with historians often leaving out that it was the South that suggested the decision of slavery by popular sovereignty and that Douglas himself simply wanted to build a railroad to California, obviously having no idea that the first planned transcontinental railroad would cause [[UsefulNotes/TheAmericanCivilWar the biggest schism ever to hit the United States]] over completely unrelated circumstances.
* In 2007, Creator/AdultSwim launched a guerrilla marketing campaign for the ''WesternAnimation/AquaTeenHungerForce'' [[TheMovie movie]] featuring battery-powered LED placards resembling the Mooninite characters being placed in numerous places around the US. However in Boston, police officials mistakenly thought that the [=LEDs=] were bombs, and treated the whole event as such. This event would turn out to known as the [[http://en.wikipedia.org/wiki/2007_Boston_bomb_scare Boston Bomb Scare]], which led to legal implications being placed on Turner Broadcasting and their contractors, the internet to make mock [[MemeticMutation "Never Forget" memes]], and forced then-current Creator/CartoonNetwork head Jim Samples to step down. It wouldn’t be long after until fans began to realize that Creator/CartoonNetwork would not be the same since the incident. Not because of any legal incidents, but because Sample’s replacement, Stuart Snyder, became the instigator of the channel’s infamous NetworkDecay, and an increase in Live action, and sitcom style shows.
* Franz von Papen, ex-Chancellor of the Weimar Republic, who in 1933 convinced President Hindenburg to make UsefulNotes/AdolfHitler chancellor in order to save his own political hide. By this point, the Nazis (forced by previous chancellors to fight repeated elections which sapped their funds) were rapidly losing support and were scraping the bottom of their piggy bank.
* Marinus van der Lubbe, the guy who started the Reichstag fire. He was a raving madman who was quickly captured that same night. It gave the Nazis the perfect opportunity to seize power, as the aforementioned repeated elections would eventually end in a loss of NSDAP seats.
* In the mid-'80s bribery scandal linked to R. Budd Dwyer (the inspiration behind "Hey Man, Nice Shot" by Music/{{Filter}}), William Smith, an attorney linked to the case, gave dubious testimony in order to accept a plea bargain, which made a guilty verdict for the former practically inevitable. As a result, Dwyer himself [[AteHisGun publicly committed suicide]] the day before the sentencing was to have taken place.
* In the night of April 14, 1912 Jack Phillips, radio operator of the ''RMS Titanic'', received a message alerting of an ice field ahead from the radio operator of the ''SS Californian'', Cyril Evans. The message interrupted an information directed to a first class passenger from Cape Race, Newfoundland, and Phillips radioed "Shut up, shut up! I am busy; I am working Cape Race!" back to Evans. Annoyed, Evans turned off the radio and went to sleep... ten minutes before the ''Titanic'' struck an iceberg. This prevented the ''Californian'' (who was the closest ship to the ''Titanic'') from hearing the ''Titanic'''s repeated distress calls and rescuing her passage before the ship went down.
* David Blair was originally slated to be Second Officer of the ''Titanic'' during her maiden voyage. However, in the last moment White Star reassigned the more experienced Henry Wilde, Chief Officer of the ''Olympic'' (at the time in drydock) to the ''Titanic'', and the knock-off effect was Blair being given another post out of the ship. By accident, Blair left with a key from the ''Titanic'', that turned out to be the only key to a safe in the Crow's Nest keeping the lookouts' binoculars. Without binoculars, the lookouts failed to see the iceberg in time.
* Jamie Gorelick, during her tenure as Deputy US Attorney General, was responsible for strengthening the restrictions on information sharing between domestic and foreign intelligence services. [[RightHandVersusLeftHand The lack of coordination]] this caused lead directly to the US government's failure to prevent the September 11th attacks, despite ample evidence of the plot, up to and including one of the terrorists being (briefly) taken into custody not long before it happened.
* Creator/SethRogen has become this with regards to the now-notorious consequences from ''Film/TheInterview'' and the cost it left Sony with. He knew that the film would piss off North Korea, and went ahead with it, presumably figuring that the DPRK would once again fail to follow up on its threats. However, he probably couldn't have seen his move as coming at the cost of the financial stability of the company he was working for, or The Guardians of Peace outright threatening terrorist attacks in theatres where it was due to play.
* On April 20, 2007, Davon Boddie was arrested for pot dealing outside of the Royal Suite nightclub in Roanoke, Virginia. Boddie was the cousin of [[UsefulNotes/AmericanFootball Atlanta Falcons quarterback]] Michael Vick, and gave Vick's home address as his own. Five days later, police searched the home and discovered a massive [[http://en.wikipedia.org/wiki/Bad_Newz_Kennels_dog_fighting_investigation dog-fighting ring]], leading to the arrest and conviction of Vick and four others.
* Gavrilo Princip and his co-conspirators in the assassination of Archduke Franz Ferdinand. All they wanted was a re-arrangement of some political borders in one part of the Balkans. What they got was a world-spanning war which was the deadliest in history, which led to the fall of the European colonial powers and the rise of communism, ''another'' world-spanning war 20 years later which became the new most deadliest war in history as a result of the mess the previous one left, and a subsequent cold war due to the results of the previous war that kept the world on the brink of destruction for fifty years. [[ArsonMurderAndJaywalking Oh, and that Balkan situation never was properly sorted out.]]
** To take it a step further, Ferdinand's driver, who was supposed to be taking him visit some people in the hospital, got lost, tried to reverse, and stalled the car almost exactly where Princip happened to be at that exact moment. Probably the most consequential wrong turn in human history.
* The TGWTG WebVideo/ToBoldlyFlee movie had a lot of effort and a lot of time put into it, but it was also a big TroubledProduction with many producers having bad memories of filming. As shown in the behind the scenes feature, things were apparently running smoothly until Rob Walker had the bright idea to lie about running fifteen minutes late. You can see Doug's face fall when he's told this, and according to [[WebVideo/TheNostalgiaChick Lindsay]] and [[WebVideo/ToddInTheShadows Todd]], that's when things started to break down.
* Best Buy's acquisition of Musicland in 2001 and their subsequent gross negligence, including making it ''[[EpicFail hemorrhage $80 million]]'' '''''[[EpicFail in one year]]''''' before selling it the following year, ultimately drove it to bankrupcy, leading to a mass closing of stores before being brought by Trans World Entertainment (owner of competitor FYE) in 2006. The mass closing of stores caused unsold stock to be taken back to the warehouses. While this has affected all home video companies, anime companies (who were 100% reliant on home video sales due to the lack of digital distribution rights at the time because [[ExecutiveMeddling the Japanese licensors refused to give them those rights]] as [[InsaneTrollLogic they equated legal digital distribution with piracy]]) were particularly severely affected, leading to the crash of the North American anime industry by the end of the 2000s, including the closures of Creator/{{ADV Films}}, Creator/{{Geneon}} and Creator/CentralParkMedia, and the downsizing and eventual closure of Creator/BandaiEntertainment. On the general side, the mass closing of the stores led to a decline of home video sales, which was further exacerbated by the growing ubiquity of streaming services such as Hulu and Netflix.
* Robert Campbeau's expansion into the United States resulted in the demise of the regional department store in the United States. To wit, Campbeau purchased Allied Stores and Federated Stores in the 1980s through junk bond [=LBOs=] but Campbeau was unable to pay it off. This, combined with a downturn in the retail industry at the time, has resulted in what many called the largest bankruptcy in U.S. history. This bankruptcy ultimately caused Macy's to start cannibalizing off stores that it inherited from both corporations beginning in the 1990s, and later on the May Department Stores company when that was merged into Macy's in 2005-2006.
* [[WesternTerrorists Dylann Storm Roof]], a white supremacist who took pictures of himself with Confederate memorabilia some time prior, shot up a church in Charleston with the hopes of dividing the nation. Not only did he [[EpicFail fail spectacularly]], he also caused collateral damage when his actions, which turned the general public (even in the South) against the Confederate flag, managed to TARFU ''Series/TheDukesOfHazzard''[='=]s reputation, if not outright FUBAR it.
* Roof's actions helped precipitate the rise of the alt-right, and subsequently the "Unite The Right" white supremacist rally at the University of Virginia in Charlottesville. Unfortunately for the alt-right, the rally caused a national crisis after one of the rallygoers mowed down a group of counterprotesters with his car, killing a young woman and injuring nineteen other people. The fallout from the attacks crippled the movement's momentum, with members losing jobs and being blacklisted from the internet. A nationwide sea change in attitudes about racism occurred, and the public began to turn against confederate imagery (as the Charlottesville protest was against the removal of a Robert E. Lee statue). The reputations of President Donald Trump and the Republican Party took a massive blow due to Trump's widely-panned response to the protest. The right's fight against antifa, the anti-fascist anarchist group who joined more peaceful counterprotesters to fight the white supremacists, was severely harpooned by the left's growing sympathy to the movement, as it was increasingly difficult to criticize a group, no matter how misguided, who fought on the same side as those killed in a terrorist attack. Most ironically, despite being called the "Unite the Right" rally, the aftermath rally ultimately divided the right and united the ''left''. Other organizations who got blamed for the rally include the ACLU, who defended the rights of the protesters, and the Charlottesville police, who did little to stop clashes between the two groups and thus failed to prevent the terrorist attack from occuring.
* The UsefulNotes/PunicWars was started by a band of mercenaries called the Mamertines who took over the city of Messana, and the Romans and the Carthaginians turn their attention away from them and then against each other over control of Sicily. What followed was years of bloody wars between the two empires, which finally ended with the destruction of Carthage.
* Faida Hamdi was a Tunisian government worker. In late 2010, she had a confrontation with a street vendor and confiscated the vendor's cart. The vendor [[SelfImmolation set himself in fire]] as a protest in front of a government building. His death [[UsefulNotes/TheArabSpring led to protests across the Middle East]] and the protests soon turned to devastating wars that would go on to shake the whole world. Today, Hamdi [[http://www.telegraph.co.uk/news/worldnews/africaandindianocean/tunisia/12054657/I-started-the-Arab-Spring.-Now-death-is-everywhere-and-extremism-blooming.html wonders]] WhatCouldHaveBeen if she did not have that initial confrontation.
* Michael Dukakis authorized weekend passes for prisoners while Governor of Massachusetts. One recipient of these weekend passes, Willie Horton, kidnapped, murdered, and raped one weekend. This ended up costing Dukakis the 1988 Presidential election after vice president George H.W. Bush's campaign pushed this heavily in an advertising campaign, and made politicians wary of being honest about their stances on crime, which led to the sudden toughening of criminal laws under Bill Clinton.
* Portuguese missionaries who threatened to conquer Japan through the forced spread of Christianity were directly responsible for centuries of de jure xenophobia in the country, which only started to be loosened (key word: started, only in 2017 did discrimination against foreigners living in the country start to significantly fade in earnest) when Matthew Perry opened trade routes between the United States and Japan in the middle of the 19th century via GunboatDiplomacy.
* The good people of Spain probably had no idea they were making world history beyond the scope of their own country when they toppled Isabela III in 1868. As even many of the revolutionaries did not even think of a Republic as a possible solution, they searched Europe for a potential King (or perhaps Queen). In the course of this search, they also contacted [[https://en.wikipedia.org/wiki/Leopold,_Prince_of_Hohenzollern Leopold of Hohenzollern]], a good Catholic, a family man in his mid thirties who seemed altogether a good candidate for the Spanish throne by the standards of the time. There was only one problem: as you might have guessed from his name, he was a (distant) relative of the Hohenzollern dynasty in Prussia and French emperor Napoleon III feared having German speaking kings in his east and west, so Leopold ultimately declined. This could have been the end of it, and indeed in most cases it would have, but Napoleon III being Napoleon III, he was not content with Leopold himself refusing, he wanted the Prussian king to renounce any claim of any Hohenzollern to the Spanish throne now and in the future. In 1870 the French ambassador bothered the Prussian King Wilhelm at a health spa in Bad Ems where the emperor was enjoying a ''Kur''[[note]]Basically a holiday that is supposed to cure ailments, still popular with Germans today[[/note]] and while the French ambassador was rude, the king was cordial and polite but basically told him "We've talked about this before, Leopold has already rejected, I am not him and I can't give promises for what my heirs might do". Unsatisfied, the French ambassador tried to bother the Prussian King again but the Prussian King in essence had a high ranking nobleman (sending anybody less would have been an affront) tell the French ambassador essentially the same thing again and that further discussing the issue was obviously pointless, the facts being what they were. Wilhelm then sent a report about those events in a telegram to his Prime Minister Otto von Bismarck. Bismarck saw an opportunity there and had the telegram shortened so that it could be read as the Prussian King rudely refusing to even meet with the ambassador (which would be diplomacy talk for "shove it up your ***") and to add insult to injury having that message delivered through some page. While Bismarck did ''not'' as he was often accused of QuoteMine the telegram, the French press published the shortened version and the reaction Bismarck intended occurred. France was furious, the emperor wanted to secure his domestic position threatened by previous foreign policy blunders[[labelnote:examples]]Like supporting Austria in the Austro-Prussian war but not actually intervening, which resulted in military loss for Austria, being outmaneuvered in the Italian wars of independence which France won for the Italians in large part but had nothing to show for except Nice or the disaster that was the Mexican Expedition which installed the brother of Austrian Emperor Franz Joseph as emperor only to have the Mexican Emperor turn rogue and end in front of a Mexican firing squad[[/labelnote]] as well as increasing demands for political liberalization and thus an ill-prepared France launched a war over what was seen by virtually everybody in Europe as a nothing-burger. France had hoped to beat Prussia and maybe call some allies to their side if the fight took longer. Not only did nobody ally with France, but all German states except Austria (which stayed neutral) rallied to the Prussian cause to fulfill secret defensive treaties. And then Napoleon III was captured near Sedan. While the newly declared Third Republic fought on, Prussia utterly wiped the floor with the French Army and ultimately France had to accept a humiliating peace treaty, that cost her five billion Francs in gold, Alsace and Lorraine and an immensurable sum in clout, credibility and respect around the world. To add insult to injury, a new German Empire was declared ''in Versailles''. This slight of course caused desire on the French part for revenge, which became one of the ultimate causes for UsefulNotes/WorldWarI which the Germans lost, causing desire for revenge in them, ultimately leading to UsefulNotes/WorldWarII. Thanks for asking about that Royal Succession thing, Spain.
* On July 1st, 2002, Swiss air traffic controller Peter Nielsen, overworked and under-equipped, spotted two planes on a collision course and ordered one of them to descend. Unfortunately, due to his workload and the fact that key pieces of his system were offline, he failed to realize that the other plane was already descending in compliance with an automated collision avoidance system, and that instead of moving the first plane ''out'' of the second plane's path, he was instead ensuring they remained ''in'' it. Predictably, the two planes collided, killing everyone on board both flights. ([[RoaringRampageOfRevenge Nielsen himself was later murdered in an act of vengeance by a man whose entire family had died in the disaster.]])
* One fateful day in 1921, a random black man in Tulsa stepped into an elevator operated by a white girl. To this day, the events of what really happened remain unknown, but regardless, the incident set off a chain reaction leading to the destruction of Greenwood Avenue.
* A barbecue held by Bruce Pearl, then-head coach of the Tennessee Volunteers basketball team, only fueled the fire of Fulmer's Revenge and ensured that it could not only not be put out on the football side, where it had originated, as soon as then-head coach Derek Dooley would've liked, it also cost Dooley his job, spread to the rest of UT athletics, and became a major wildfire, as it were. What's worse is that [[ArsonMurderAndJaywalking Pearl's successor, Cuonzo Martin, never really got to show off his true potential as a UT basketball coach in the three seasons he was with UT before he resigned to coach the California Golden Bears]]. Read all the sordid details [[https://allfortennessee.com/2018/07/13/tennessee-vols-13-unlucky/5/ here]],[[https://allfortennessee.com/2018/07/13/tennessee-vols-13-unlucky/6/ here]], and [[https://allfortennessee.com/2018/07/13/tennessee-vols-13-unlucky/10/ here]].

* Lieutenant Gorman's last act in ''Film/{{Aliens}}'' indirectly causes the events of ''Film/Alien3''. The blast from the grenade he uses to commit suicide with causes Newt to fall into the flooded section of the colony where she gets abducted by the aliens. This forces Ripley to rescue her from the atmosphere processor, giving the Queen alien a chance to stow away to the ''Sulaco''. [[spoiler:The eggs the Queen managed lay aboard ship eventually kill ''everyone'' in ''Alien 3''.]]

Added DiffLines:

** House Greyjoy's invasion of the North and Theon's raid of Winterfell not only disrupted the Stark supply lines in the War of the Five Kings, but demoralized Robb and helped convince Roose to betray him. If the Ironborns had stayed out of things, the war may have gone quite differently.
