*** However, Quentin's story [[UnreliableNarrator it should be taken with a grain of salt]] for three reasons: 1) he works for Stark Industries, meaning that every project he works is Stark Industries' property and, by extension, Tony's, 2) Tony himself admits that the name he gives to that project is a shitty one that had to be changed and 3) Quentin mention that everyone laugh at the name but, in truth, Film/CaptainAmericaCivilWar shows that the audience never make any laugh. [[spoiler:Quentin admits he was officially fired for being "unstable", which seems fairly accurate.]]

As brought up in ''Film/CaptainAmericaCivilWar'', Superheroes, individually or as in a group, tend to directly or indirectly cause an amount of the conflict they themselves have to fix later on. This can be attributed to toying with things they don't understand to not sticking around to personally supervise or help with the clean up.

** ''Film/SpiderManFarFromHome:'' Tony Stark taking the credit for one of his technicians' virtual-reality projects, giving it a demeaning name and then firing the guy [[spoiler:means technician Quentin Beck becomes Mysterio, the guy who almost destroys London and outs Spider-Man's identity while also using a FrameUp to turn him into a HeroWithBadPublicity. In fact, Mysterio's entire ''crew'' are ex-Stark Industries employees (one of whom was the man on the receiving end of Obadiah Stane's "box of scraps" [[Memetic Mutation rant]]) who feel slighted.]]

* Odin's biggest mistake was how he treated Loki. By favoring Thor over Loki, lying to Loki his entire life, and letting the boys grow up thinking that Frost Giants were irredeemable monsters, Odin positioned Loki to have a psychotic break once he learned the truth -- which leads to Loki desperately trying to prove he's a worthy son who's loyal to Asgard while decrying any link to the "monsters," even if that means tricking and murdering his birth father, sending the Destroyer against Thor, and trying to destroy all the Frost Giants for good. Loki's actions in ''Film/{{The Avengers|2012}}'' likewise stem back to Odin's bad parenting choices.[[note]]That's not even counting Loki's motivation for disrupting Thor's coronation ceremony to begin with, and goading a hot-headed Thor into attacking Jotunheim, both of which stem back to Loki's loyalty to Asgard and the rivalry in which Odin raised his sons.[[/note]]

** In ''Film/SpiderManFarFromHome'': [[spoiler:he leaves the Earth and has a pair of well-meaning but under-qualified Skrulls pretend to be him and Maria Hill. Talos and Soren have no idea how to handle the crisis that unfolds, don't know how to contact any superheroes besides Spider-Man, and buy Mysterio's lies wholesale until it's nearly too late.]]

* Perhaps his biggest one was not killing Thanos immediately [[AndThisIsFor and stopping to gloat,]] allowing Thanos to cause the Decimation.

* It's the fault of the whole team, not just Cap, but the "time heist" in ''Film/AvengersEndgame'' very nearly gave Thanos everything he wanted. The Avengers travel back in time to recover the infinity stones from earlier in their timelines, in order to undo the snap. It all goes off without a hitch, until 2014 Thanos discovers the time-traveling Avengers, and captures Nebula, allowing him to travel back to the present, where the Avengers have ''already assembled an Infinity Gauntlet for him'', essentially stopping just short of gift-wrapping it. Even worse, when Thanos learns to what lengths the Avengers have gone to in order to undo the snap, he realizes that leaving half of the universe alive was a mistake because the half that remained would always remember what they lost and resent Thanos for it. As a result, Thanos resolves to use the gauntlet to [[OhCrap destroy the]] [[FromBadToWorse ENTIRE universe]] [[KillEmAll this time]], and create a new one where [[AGodAmI everyone worships him]]. That's right, ''Endgame'' is the movie where the Avengers not only turn Thanos into an OmnicidalManiac, but also nearly give him all the tools he needs to put his beliefs into action![[note]]He already was an OmnicidalManiac to some extent in ''Infinity War'', but now he is no longer a WellIntentionedExtremist in doing so.[[/note]]

** Tony Stark revealing himself as Comicbook/IronMan in ''Film/IronMan1'' allows Ivan Vanko to come after him directly in ''Film/IronMan2'', with all the incidental casualties that that may have caused.

* Tony, under the influence of Wanda's vision and with the help of Bruce Banner, used the Mind Stone in order to create Comicbook/{{Ultron}} - an AI which should've ensured the survival of Earth. Then [[AIIsACrapshoot Ultron]] turned against Avengers.
** ''Film/CaptainAmericaCivilWar'' added another layer to that one: destruction of Sokovia caused numerous casualties, among them was the family of [[BigBad Helmut Zemo]], whose RoaringRampageOfRevenge caused the events of the movie.
** ''Film/SpiderManFarFromHome:'' Tony Stark taking the credit for one of his technicians' virtual-reality projects, giving it a demeaning name and then firing the guy [[spoiler:means technician Quentin Beck becomes Mysterio, the guy who almost destroys London and outs Spider-Man's identity while also turning him into a HeroWithBadPublicity. In fact, Mysterio's entire ''crew'' are ex-Stark Industries employees who feel slighted.]]

* She then gives all of the avengers (apart from Clint) nightmarish visions, including the Hulk, driving him into a rampage through Johannesburg.

* In ''Film/AvengersInfinityWar'', Iron Man, Dr. Strange, and Peter come up with a plan to ambush Thanos and get the Infinity Gauntlet away from him, ending the threat he poses. The plan is going off without a hitch when Peter discovers that Thanos murdered Gamora and, instead of helping the others, he instead angrily strikes Thanos. This forces Iron Man to stop trying to remove the gauntlet ''and'' causes Thanos to snap out of the trance Mantis put him in. Spider-Man had just succeeded in getting the gauntlet off of Thanos's hand but him waking up when he did meant that he was able to reclaim it. Thanos was then able to get the Time Stone from Dr Strange, then go to Earth to get the Mind Stone from Vision and, with all six stones, kill half the universe.

* ''Film/SpiderManHomecoming'': This is pretty much all Peter does. The entire movie is Peter trying to be a hero, botching it, then later is forced to neglect his normal responsibilities as Peter in order to clean up the mess he made as Spiderman, further botching it, and repeat.

** To his credit, Peter goes to a trusted adult to confide in once he has more information - [[spoiler:unfortunately, said trusted adult is just another one of Mysterio's tricks, and he gives Beck the information he needs to go after MJ, Ned, and Betty.]]

** In the mid-season finale of season 3, Coulson defeats [[spoiler: Ward]], the HYDRA agent who betrayed Coulson and his team, became a major adversary of Coulson's, killed numerous S.H.I.E.L.D. agents, tortured and seriously injured [[spoiler: Bobbi]], tried to have [[spoiler: May's ex-husband Dr. Garner]] assassinated, and murdered [[spoiler: Rosalind Price, the woman Coulson was in love with]]. Faced with the option of abandoning him to an almost certain death on a barren planet or killing him right then and there, [[spoiler: he chooses the latter]]. This allows [[spoiler: Hive, an Inhuman so dangerous, his own kind banished him to another planet, to assimilate Ward's corpse and return to Earth]], as well as accomplishing HYDRA's primary objective of [[spoiler: bringing Hive back.]]

** Jessica Jones tries very hard to ensure Kilgrave is arrested and tried to allow Hope to get exonerated. In doing so, due to Kilgrave's powers and connections, many people end up dead or their lives shattered. She does come out better for it, but had she killed him from the outset, she and Hope would have been in jail, but a lot of innocent lives would not have been taken in the process.

* Long ago[[note:Thor Ragnarok spoilers]], Odin [[spoiler:banished his daughter Hela to an unknown dimension; after his death, because he had never told anyone else alive about Hela, she was able to escape and conquer Asgard, forcing Thor to destroy his own kingdom to stop his sister]].

** To his credit, Peter goes to a trusted adult to confide in once he has more information - [[spoiler:unfortuntely, said trusted adult is just another one of Mysterio's tricks, and he gives Beck the information he needs to go after MJ, Ned, and Betty.]]

* Odin's banishing of Comicbook/{{Thor}} helps show Comicbook/NickFury that the Earth is not ready, and indirectly helps him become more paranoid, leading to many of his experiments.

** As part of the Cap's plan to bring down HYDRA, Comicbook/BlackWidow leaked all of HYDRA's files onto the internet. Helmut Zemo was able to find valuable secrets among the documents, which enabled him to enact his RoaringRampageOfRevenge against the Avengers.

When confronting his brother N'Jobu over stolen Vibranium, T'Chaka killed him to protect [[spoiler:Zuri]] and abandoned N'Jobu's son in the slums of Oakland to preserve the secrecy of Wakanda.

** In the season 2 premiere, we learn that Simmons [[spoiler:left S.H.I.E.L.D. because she thought Fitz's recovery from the brain damage he sustained would progress better if he didn't become dependent on her]]. Unfortunately, this backfires ''hard'': [[spoiler:Fitz is literally unable to cope with her leaving, having a complete breakdown that ends with him [[ImaginaryFriend hallucinating a version of Simmons]] that he relies on for companionship, support and assistance. Oh, and the effects of his brain damage - already more severe than he realises - are getting worse as well, possibly because of his breakdown, possibly because Simmons ''was also his medic'' and there doesn't seem to be anyone else working towards his recovery]]. This is later subverted when it turns out [[spoiler: Simmons was actually infiltrating HYDRA]] and Coulson did not want to risk revealing this information to anyone else.
