11
12	# The villain was [[EnfanteTerrible just a kid at the time]].
13	# The people killed included [[SelfMadeOrphan the villain's family]].
14	# The villain had [[ForTheEvulz no real reason to do this]].
15	# The villain [[GenocideFromTheInside killed off his entire people or clan]] in doing this.

23	[[folder:Anime & Manga]]
24	* ''Manga/{{Berserk}}'' sees to it what is arguably one of ''the'' most infamous examples in all of manga with [[spoiler:[[TheBeautifulElite Griffith]] ascending to becoming a demon during the once-every-[[NumberOfTheBeast 216]]-years even called [[TotalEclipseOfThePlot The Eclipse]]. [[JumpingOffTheSlipperySlope Over a gradual descent]] from [[FromNobodyToNightmare nothing into the monster he is now]], he [[EtTuBrute betrayed everyone he ever lead and cared for]] after [[BrokenAce wounding up broken in mind and body from a year of torture]], [[DeityOfHumanOrigin rejecting his humanity to ascend to godhood]] and [[HumanSacrifice brutally sacrifice his entire army for a second chance at life]]. To make a ''very'' long story short: [[CurbStompBattle it]] ''[[AnyoneCanDie does]]'' '''''[[RapeIsASpecialKindOfEvil NOT]]''''' [[DevouredByTheHorde end well]] for anyone not [[SatanicArchetype Griffith]], [[DemonLordsAndArchdevils the God Hand]], or [[TheLegionsOfHell the Apostles]]. The end result was so devastating that there were only ''two'' survivors from the massacre (who only lived thanks to [[BigGood The Skull Knight]]'s [[BigDamnHeroes timely intervention]] in an event that going by the God Hand's reaction had never happened before), one of which was [[RapeLeadsToInsanity driven to insanity from being raped by the newly-reborn Griffith]] and the other losing an arm, eye, and getting a [[JerkJustifications factory reset]] into becoming a textbook WoobieDestroyerOfWorlds in his [[RoaringRampageOfRevenge demon gore-soaked trail for revenge]]]].
25	* VillainProtagonist [[LightIsNotGood Light]] [[MagnificentBastard Yagami]] of ''Manga/DeathNote'' takes his first step into corruption and madness when he goes on a massive killing spree after receiving the [[ArtifactOfDeath Death Note]]. Of course, he is not a little kid at the time (he's [[TeensAreMonsters seventeen]]), he doesn't kill his family ([[spoiler:at least, not then]]), and he has a number of reasons for doing so (mostly because he's bored, disillusioned, and insane). That first week racked up a body count of five hundred.
26	-->'''Ryuk:''' ...[[DeadpanSnarker You've taken quite a liking to it]].
27	* Sometimes the bloodbath happens because [[BewareTheNiceOnes the person in question got pushed too far and snapped out]]. Just take a look at Lucy from ''Manga/ElfenLied'' and what she did to the [[KidsAreCruel cruel kids]] in her backstory for beating the puppy that she'd started caring for to death.
28	* In ''Manga/FairyTail'', the [[GreatOffscreenWar Dragon King Festival]] of 400 years ago was this for [[TheDreaded Acnologia]], during which he JumpedOffTheSlipperySlope and [[WithGreatPowerComesGreatInsanity completely fell prey to his magic's darker influences]]. The end result was him indiscriminately killing friend and foe, human and dragon alike until he more or less wiped out the dragon race and turned into a dragon, crowning himself the "Dragon King".
29	* An '''extreme''' example occurs in ''Literature/FromTheNewWorld''. The anime deals with a new age of mankind in which humans have developed telekinetic abilities. Unlike most anime of this genre, this anime explores the more realistic possiblities that could happen if even just one person develops such powers. Boy K (no real name given) seemed to just be a quiet child, but psychological exams revealed disturbing [[TheSociopath sociopathic]] tendencies. No one knew what to do with him, but they waited too long. Eventually, in the middle of class, Boy K let go of his humanity and ''tore his teacher apart limb from limb''. He didn't stop there. He went on a full out rampage. Boy K slaughtered over 1,000 people ''on the first day '''alone'''''.
30	* ''Manga/FullmetalAlchemist'': Scar began his serial-killing career by killing any and all available Amestrians [[spoiler:after waking up in a hospital to find that his entire family has been killed by Kimblee and that his [[BadassTransplant brother's arm has been grafted onto his body]] in the place of his own severed arm]]. He flipped out and started his rampage with [[spoiler:the Rockbells]], two Amestrian doctors who saved his life. While the slaughter is indeed his StartOfDarkness and he becomes an unrepentant murderer afterwards, he does actually regret this particular action even before [[spoiler:his HeelFaceTurn]] and acknowledges that the two doctors did not meet even his warped definition of guilty.
31	* ''Manga/MyHeroAcademia'': While [[spoiler:Tomura Shigaraki]] UsedToBeASweetKid, this came to an abrupt end when [[spoiler:his [[MakeThemRot Quirk]] activates for the first time [[TraumaticSuperpowerAwakening following a beating]] from his [[AbusiveParents abusive father]]. He [[AccidentalMurder accidentally kills]] most of his family, before becoming a SelfMadeOrphan by deliberately murdering his father. [[GreaterScopeVillain All For One]] finds him soon after this and decides to groom him to become the leader of the League of Villains, triggering his StartOfDarkness in earnest]].
32	* ''Manga/{{Naruto}}'' has several examples.
33	** Zabuza is the earliest, having killed over a hundred potential graduates of his village despite not having any shinobi training himself. He was made a shinobi as a result and still remembers that event fondly. He's not quite a straight example, though; his actions brought needed reforms to the Shinobi education system of the Hidden Mist Village, by singlehandedly forcing them to end their SocialDarwinist approach, and was also the last antagonist to comport themselves as professionals rather than screwed up psychopaths. One gets the feeling he cultivated his reputation as a Devil of the Hidden Mist for the sake of psychological warfare against targets.
34	** Itachi and Sasuke have a shared example in the destruction of the Uchiha clan. Despite being a young teen, Itachi single-handedly wiped out his entire clan aside from Sasuke before going on the run. He stated the purpose was to test his own skill [[spoiler:but it was actually to prevent them launching a coup]]. The trauma of this would later lead to Sasuke turning villain.
35	** Hidan was annoyed that his village converted to a peacetime economy so he slaughtered his neighbors, potentially including his family, and went missing-nin. His partner Kakuzu was originally a loyal shinobi but after he was punished and imprisoned for failing in a near-impossible task he turned on them, slaughtering a large number of his comrades before becoming a bounty hunter.
36	** After seeing his teammate and love interest [[spoiler:Rin]] killed by [[spoiler:Kakashi]], [[spoiler:[[FallenHero Obito Uchiha]]]] loses it in a violent and brutal display of primal fury and goes about slaughtering the enemy ninja who drove the two into that position in the first place. Thus opening the path to his career as [[MalevolentMaskedMan Tobi.]]
37	* ''Manga/NegimaMagisterNegiMagi'': While the extent of her evil is ''[[NobleDemon very]]'' debatable, the infamous criminal mage [[TheArchmage Evangeline]] [[OurVampiresAreDifferent McDowell]] is implied but not outright stated to have killed her family when she had just turned into a vampire at 10 years old. Though it is heavily implied she was either not in control of herself when it happened or she wasn't conscious of it and only realized what she had done after she saw the corpses and the blood on her hands and mouth.
38	* Rob Lucci of ''Manga/OnePiece'' is a perfect example. His first mission as a [=CP9=] agent was given to him when he was only a kid; to save some hostages from pirates... he killed not only the pirates, but all the hostages as well, because they were getting in the way/didn't deserve to live. And he got a nasty-looking scar on his back in the process, which coincidentally looks like the World Government flag.
39	* There's quite a few sympathetic starts of darkness in ''Manga/RurouniKenshin'', but the one closest to this trope is when [[StepfordSmiler Seta Soujirou]] murders his abusive relatives after they pushed him one time too many and ended up as TheDragon for a SocialDarwinist.
40	* ''Manga/YuYuHakusho'': Sensui's StartOfDarkness was like this: he [[GoMadFromTheRevelation flipped out]] upon learning HumansAreTheRealMonsters, and killed everyone in the Black Black Club's villa. Coincidentally, the people he murdered were themselves enjoying a demon blood bath.
41	[[/folder]]
42
43	[[folder:Comic Books]]
44	* The Plutonian from ''ComicBook/{{Irredeemable}}'' kicked off his reign of terror by leveling his patron city and massacring the inhabitants.
45	* He's actually the protagonist (one hesitates to say "hero") rather than the antagonist a lot of the time, but ComicBook/{{Lobo}}'s origin story involves him killing off his entire ''race'' except for himself, because he was dissatisfied with the grade he received on a school project. PlayedForLaughs, since Lobo was originally a DeconstructiveParody of the NinetiesAntiHero.
46	* ''ComicBook/{{Purgatori}}'': The titular character was just a beautiful and young slave girl named Sakkara that was taken as a concubine by Queen Ostraca, until her generals forced her to put her entire harem to the sword to ensure the kingdom's stability. Sakkara managed to evade the massacre and found an ancient vampire lord who offered her immortality and a chance for revenge. She accepted and his bite turned her into a half-vampire, half-demonic woman, whose first act was to crash Ostraca's wedding and kill everyone inside, except for her former lover and her groom whom she inflicted AFateWorseThanDeath by turning them into vampires and locking inside their tombs.
47	* ''[[ComicBook/TheUltimates Ultimate Avengers]]'': Up until his sixteenth birthday, the Red Skull seemed like a nice, relatively normal kid, being cheerful and intelligent to all the soldiers on the secret US military base he was raised on. Then, the day he turned sixteen, he massacred every living person on the base, cut his face off and ran out into the world to commit mayhem for the giggles.
48	* ''ComicBook/UsagiYojimbo'': As revealed in a later story, [[spoiler:the first thing [[KnightTemplar Jei]] did upon coming into existence was to slaughter everyone in the temple he happened to be in.]]
49	[[/folder]]
50
51	[[folder:Fan Works]]
52	* ''Fanfic/BoldoresandBoomsticks'': Ruby's account of Grendel's origin tells that it was once a normal Beowolf Alpha before losing its paw to a huntsman. It then organized the slaughter of everyone at a party except said huntsman, choped off his hand, chased him to a village, and left only one survivor in the village to tell the story.
53	* With the last character imaginable in ''[[https://archiveofourown.org/works/28644663/chapters/70214727 Creation and Destruction]]''; [[spoiler: Mt. Lady]] got turned into the HeroKiller Sinner, taking up Stain's [[HeelFaceTurn abandoned]] ideals and a fire axe... which she promptly used on Death Arms and her own production crew, live, ''on camera.''
54	* ''Fanfic/TheFlashSentryChronicles'' has an example that combines Types 1, 2, and 4. Shadow Corrupter was originally a kind unicorn by the name of "Gleaming Path", but on his thirteenth birthday he discovered that his parents and most of the villagers of Weeping Wood Hallow are part of a cult that worships the Corrupted Shadow, and plan to use him in a [[HumanSacrifice sacrificial ritual]] to revive it, since his birthday was on the day that the Corrupted Shadow was killed. He ends up being put through the ritual against his will, which included being cut multiple times by daggers. Ultimately, the ritual was a success and he was revived, now granted with his powers, [[BeCarefulWhatYouWishFor but he immediately took his revenge on the cult]], destroying the entire village and everyone in it for what they did to him, and not just the members of the cult but the ''entire'' village, including all his friends.
55	* In ''Fanfic/TheJadedEyesSeries'', Harry snaps and murders the Dursleys when he's six years old.
56	* In ''Fanfic/PonyPOVSeries'', this happened with Lord Tirek (who's a CompositeCharacter of the G1 and G4 Tireks). The Prince of the Centaur Empire, Tirek was power hungry and fiercely feared losing his claim to the throne. Eventually, he ended up intentionally absorbing an ungodly amount of dark magic [[spoiler:from one of Pandora's Boxes that [[{{Satan}} Morning Star]] released into the mortal world]] and after spending some time mastering it, [[GenocideFromTheInside brutally annihilated his own kind]].
57	* [[VillainProtagonist Sni]][[SerialKiller vy]] from ''[[https://www.youtube.com/watch?v=3WRr-KQjDxA La Sangre de Mi Sangre]]'' is another one of those rare characters who manage to fulfill ''every condition for it''. To elaborate, she was an EmptyShell CreepyChild who one day found a lost Garchomp, so she keeps him company, as time passes the Garchomp falls in love with her, she pretends to go along until she ends up BecomingTheMask. When her sister finds out and [[KnightTemplarBigBrother she]] [[PaedoHunt kills him]]. Snivy, having watched this in secret, decides to go the BestServedCold route, preparing a trap for her sister and after she was done killing her, went back home and killed all her remaining family and friends for [[ForTheEvulz no real reason, even admitting as such]].
58	* ''WebAnimation/WhereWasMyHero'' shows a truly ''chilling'' types 1 and [[WhereIWasBornAndRazed 4]] example with none other than [[spoiler:[[Franchise/SonicTheHedgehog Tails]]; set in an alternate universe where he never meets Sonic]], his life gets worse and worse until he becomes an AxCrazy WoobieDestroyerOfWorlds with OmnicidalManiac tendencies.
59	[[/folder]]
60
61	[[folder:Films -- Animation]]
62	* ''WesternAnimation/KungFuPanda'': Depending on [[BloodlessCarnage how much]] damage he actually did (it's ambiguous but he definitely at the very least endangered numerous civilian lives and caused a huge amount of property damage), Tai Lung when he learned he would not be the Dragon Warrior. In the sequel, Lord Shen heard a prophecy which implied that a panda would bring about his downfall and responded by conducting a genocide against the pandas, [[SelfFulfillingProphecy which ended up with baby Po in the Valley of Peace and ultimately set him on his path to the events of this film]].
63	* ''WesternAnimation/MonstersVsAliens'': Although we hear [[JackhammeredConversation little]] of Gallaxhar's back story, he does directly state that he was the one who [[EarthShatteringKaboom blew up his home planet]].
64	[[/folder]]
65
66	[[folder:Films -- Live-Action]]
67	* Deborah, the villain in ''[[Film/TheAddamsFamily The Addams Family Values]]'', is murderous GoldDigger who's first murder is her own parents. The reason she burned their house down is that [[EvilIsPetty they gave her the wrong Barbie doll]].
68	* ''Film/DraculaUntold'', Vlad himself, ''twice''; first when he first gains his vampire power and proceeds to CurbStompBattle an invading army, then when he [[spoiler: loses his wife]] and hits his DespairEventHorizon, he proceeds to do so ''again'', but not until after turning what's left of his people into vampires.
69	* The original ''[[Film/{{Halloween 1978}} Halloween]]'' is one of the greatest, most notorious examples of this trope across all media, playing it entirely straight and fulfilling all three conditions. Michael suddenly flipped and, for no good reason, killed his older sister. Eventually, Dr. Loomis concludes that there's nothing to him, except evil.
70	* ''Film/SpiderMan2'': Arguably Otto Octavius' villain origin is his arrogant refusal to shut down his unstable fusion generator, which results in the death of his wife. But the very much sentient actuators fused to him have ''their'' first go when they viciously slaughter an entire room full of surgeons that were preparing to operate on the unconscious Octavius, in one of the most horrifying scenes of the trilogy. Octavius' horrified BigNo when he wakes up to a room full of dead bodies shows that he knows there's no going back for him from that.
71	* ''Franchise/StarWars'':
72	** In the prequel trilogy, Anakin Skywalker's StartOfDarkness (murdering a camp of Sand People) and later his attack on the Jedi Temple. The slaughter of the Tusken Raiders was because they tortured and killed his mother, and no bones are made about it--both of these massacres involved him slaughtering women and children, too.
73	** In the [[Film/TheForceAwakens sequel]], Kylo Ren's backstory involves him and the Knights of Ren killing all of [[spoiler:his fellow padawans in his uncle Luke's New Jedi Order. [[VillainousLineage Like grandfather]], [[DiscussedTrope like grandson]]...]].
74	[[/folder]]
75
76	[[folder:Literature]]
77	* ''Literature/HarryPotter'': Sirius Black killing a bunch of innocent bystanders [[spoiler:is a subversion, as it was Peter Pettigrew who did so and for whom this trope does apply]].
78	* ''Literature/{{Heimskringla}}'': [[FounderOfTheKingdom Harald Fairhair]] gives his favorite son Eirik command of 5 longships (which would amount to at least 150 men) at the [[RaisedByOrcs tender age of 12 to go on a]] [[RapePillageAndBurn viking expedition]]. When he come home, he quickly gets the moniker ''[[NamesToRunAwayFromReallyFast Bloodaxe]]''.
79	* ''Literature/{{Mistborn}}'' has a rare AntiHero example in Kelsier, who Snapped (i.e. became able to use his superpowers) after seeing his wife beaten to death by her overseers when they were slaves. "Many men had died that night."
80	* ''Literature/PleaseDontTellMyParentsIHaveANemesis'': Penny plays the game ''Little Reaper Girl'', about the hero Psychopomp's early life. It's a stealth game that involves killing hundreds of people while trapped in some sort of dome. Penny assumes that's just the game upping the kill count like normal, but she reads up on what actually happened and is shocked to discover it's actually accurate.
81	* In the ''Franchise/StarWarsLegends'', the origin story of Palpatine/Darth Sidious involves him throttling his family and their bodyguards to death, and intending to at the very least kill his father since he was born due to hatred of him, and for no reason other than his family forbidding his contact with Plagueis, as revealed in ''Literature/DarthPlagueis''.

84	[[folder:Live-Action TV]]
85	* When ''Series/{{Angel}}'' first became the vampire Angelus, he proceeded to kill every single living person in his village in Galway, Ireland, starting with his own family.
86	* ''Series/{{Arrow}}'': In "[[Recap/ArrowS6E6PromisesKept Promises Kept]]", we discover Slade Wilson's BackStory before he became Characters/{{Deathstroke}}. After getting off the island of Lian Yu, he decided to get out of active service for ASIS, working as a trainer instead. However seeing the news report that Oliver Queen was alive triggered his [[PsychoSerum Mirakuru-madness]]. When he snaps out of it, he realises he's slaughtered his fellow ASIS operatives with a katana.
87	* The ''Series/CriminalMinds'' episode "[[Recap/CriminalMindsS5E2Haunted Haunted]]" begins with a man having a psychotic break at a pharmacy and killing a number of the other customers.
88	* Ben Linus on ''Series/{{Lost}}'' got his Start of Darkness by assisting [[spoiler: the Others in poison-gassing all forty of the DHARMA Initiative settlers]]. He gets 2 1/2 bonus points: he killed his [[spoiler: father, making himself an orphan]]; he was a member of the community he destroyed; and he gets half a point for being barely out of his teens.
89	* [[spoiler:Rumpelstiltskin]] in ''Series/OnceUponATime'' goes on a killing spree after suddenly acquiring awesome powers. Justified by the fact that they were all soldiers trying to conscript his barely 14 year old son, and he was trying to protect the kid - but he was still evil, since the power was dark and corrupted him.
90	-->[[spoiler:'''Rumple]]:''' ''(SlasherSmile)'' You're safe, Bae. Do you feel safe, son?\
91	'''Baelfire:''' ''(horrified)'' No...
92	[[/folder]]
93
94	[[folder:Tabletop Games]]
95	* ''TabletopGame/EclipsePhase'' includes "The Lost Generation", an attempt at accelerated maturation GoneHorriblyWrong that are all assumed to be this. Several of the survivors of the program ARE this, but not nearly all of them.
96	* ''TabletopGame/ForgottenRealms'': Sammaster's fall started in somehow similar way - he blasted slavers with spells, but in the process also caused the deaths of the very people he tried to rescue. Not that he was the shining example of mental stability before this.
97	* ''TabletopGame/SentinelsOfTheMultiverse'':
98	** Played straight with Citizen Dawn, whose first real experience with her powers killed a bunch of people and destroyed a library, and [[LackOfEmpathy she was mostly concerned with...the books.]]
99	** The first sign that [[EnemyWithin Dark Visionary]] was taking over the Visionary was when she murdered a bunch of scientists who were too close to discovering her secret.
100	** Spite's turn from a petty nuisance to a serious threat was cemented when he murdered two of the Wraith's best friends out of revenge.
101	** Inverted with Ambuscade, who began his HeelFaceTurn by teaming up with the more heroic Mainstay by wiping out most of a Mexican drug cartel - at the end of a villainous career where he ''risked'' plenty of lives, but basically never managed to actually ''take'' any.
102	* ''TabletopGame/Warhammer40000'' has Angron, Primarch of the World Eaters. He was once a gladiator slave who along his fellow gladiators fought their way out to freedom against their Nucerian slavers. The Emperor sought him to join his crusade, but Angron refused, choosing to stay and die along side his brethren who are about to be cornered by the Nucerian armies. The Emperor then teleported Angron alone into his ship, leaving his fellow warriors to be slaughtered by the Nucerians. Angron never forgave the Emperor for what he did, when he became Primarch of the World Eaters his legion became the most brutal of them all, when Horus turned to Chaos he was one of the first Primarchs to join him, and soon became a Daemon Prince of Khorne. Indeed, when Angron was found by the slave traders who eventually sold him to the gladiatorial arena, he was naked, drenched in gore, and surrounded by the corpses of the Eldar assassination squad he'd butchered in self-defense when they attempted to murder him to pre-empt his falling to Chaos. He was just a little boy at the time.
103	* ''TabletopGame/{{Warhammer}} Fantasy Battles'':
104	** Vilitch the Curseling used to be a shaman's apprentice, the weaker of two twins, constantly bullied and ridiculed for his weakness. When his prayers attracted attention of Chaos god Tzeentch, he was granted powerful magic as well as a powerful body to match (he was magically grafted on top of his brother's shoulders) His first act was to turn his power against the tribe, making the village "run with molten flesh".
105	** One rendition of Archaon's backstory relates that after having been driven insane by what he read in the Book of Necrodormu, he then slaughtered his family in cold blood before fleeing to Norsca.
106	* ''Very common'' angst-oriented origin story for both good and evil Werecreatures in ''TabletopGame/WerewolfTheApocalypse''. A tradition continued in ''TabletopGame/WerewolfTheForsaken'', which, if anything, enforces the "don't forget that you're playing a monster" thing more harshly than its predecessor. The books make it quite clear that, if you're a Rahu (warriors who changed under the full moon), your First Change most likely involved someone dying horribly.
107	[[/folder]]
108
109	[[folder:Video Games]]
110	* In ''VideoGame/FableII'', if the player feels so inclined, after getting a sword they can slaughter the gypsies who raised them as a nice little warm-up before carving a bloody swath across Albion.
111	* ''VideoGame/FatalFrame'': [[spoiler:Kirie Himuro and Lord Himuro]] from ''VideoGame/FatalFrameI'', [[spoiler:Sae Kurosawa]] from ''VideoGame/FatalFrameII'', and [[spoiler:Reika Kuze]] from ''VideoGame/FatalFrameIII''. Except for [[spoiler:Lord Himuro]], all resulted directly from a botched sacrifice, and [[spoiler:Himuro]] got the curse second-hand. They all suddenly engaged in mass-slaughter, and their victims became enraged, vengeful ghosts themselves who continued to claim victims decades or even centuries after.
112	* ''VideoGame/FinalFantasyVII'': Sephiroth begins his FaceHeelTurn with the infamous massacre at Nibelheim.
113	* The Death Knight from ''VideoGame/FireEmblemThreeHouses'', or as he's more commonly known, [[spoiler:Jeritza Von Hrym,]] though his real name is [[spoiler:Emile Von Bartels]]. [[spoiler:His childhood as Emile wasn’t exactly nice, with his father using Mercedes' mother as a BabyFactory to create children that bear her Crest. When Mercedes and her mother escaped, an 11-year-old Emile chose to stay to protect them from their father’s wrath. Years later, when his father found where they were hiding, Emile was driven to murder his father and the entire House Bartels in a blind rage when his father learned Mercedes’ mother was too old to have children, choosing to use Emile’s sister Mercedes instead, who was still a teenager.]] While he feels no regret for these actions, the event was so traumatizing that he began to become a full-on BloodKnight that would even kill [[spoiler:his big sister.]]
114	* In ''VideoGame/FirstEncounterAssaultRecon'', Paxton Fettel fell into this trope as a kid during the so called "synchronicity event", during which he was possessed by Alma and killed several scientists using his psychic powers.
115	** We get to see the event in the third game. [[TheGuardsMustBeCrazy Against all logic, the soldiers repeatedly walk in front of a psychic powerhouse who proceeds to implode them after a few seconds of concentration, only stopping when he burns out]].
116	* So how does ''VideoGame/SoulNomadAndTheWorldEaters'' infamous [[VillainProtagonist Demon Path]] begin? [[WhereIWasBornAndRazed By killing everyone in your village, of course.]]
117	* ''VideoGame/SuikodenIV'' has Graham Cray, who is considered responsible for the destruction of his hometown in a Type 2. [[spoiler:In reality, it was his son who fatally unleashed the full power of the Rune of Punishment against soldiers running a FalseFlagOperation. Becoming TheScapegoat on top of everything else just drove him into villainy.]]
118	* ''VideoGame/TraumaTeam'''s CR-S01 unleashed a bioterrorist attack that killed everyone in Cumberland College, but with a twist - he has no memory of how or why he did it. [[spoiler:It turns out that he was actually framed by his adoptive father Albert Sartre.]]
119	* A No Mercy run in ''VideoGame/{{Undertale}}'' starts out like this, with the player being required to track down every RandomEncounter in the stage and kill them.
120	* In ''VideoGame/{{Valis}} II'' (Japanese computer version), the origin story of Cruel King Megas is that, after being exiled by his kingly father, he returned to slaughter his entire family, tearing his brothers to pieces and eating his mother. He was thwarted by his father's HeroicSacrifice, turning him into a SealedEvilInACan, which prevented further bloodshed... until the seal was broken.

123	[[folder:Visual Novels]]
124	* Joe Darke in ''Franchise/AceAttorney'', a businessman who panicked after accidentally running over a man with his car and started to [[LeaveNoWitnesses kill the witnesses of the accident]] (and the witnesses of ''those'' murders too).
125	[[/folder]]
126
127	[[folder:Webcomics]]
128	* ''Webcomic/DanAndMabsFurryAdventures'' has a relatively sympathetic example in Regina Darkblood, who accidentally kills an innocent civilian and then kills several adventurers because of a tragic case of the universe's equivalent of MistakenForPedophile. Not helping matters is that her family was ''proud'' of her for embracing her species' MightMakesRight philosophy with a traditional GTA-like [[BringIt aggro of her victims' friends and relatives]].
129	* They aren't all ''necessarily'' villains in the normal sense, but most times the first notice the world has of a new "Spark" (mad scientist) in ''Webcomic/GirlGenius'' is the total depopulation of some village, usually that of the Spark.
130	* Helen Narbon in ''Webcomic/{{Narbonic}}''... insofar as she can be considered a villain. And it wasn't as much blood as tomato sauce and pesto. With tentacles. Apparently all mad scientists try to cause as much carnage as possible when they [[InsaneEqualsViolent go mad]] and get [[TheSparkOfGenius mad science abilities]]. Some of them were already evil before they were mad.
131	[[/folder]]
132
133	[[folder: Web Original]]
134	* Mandragora in ''Website/TheCrewOfTheCopperColoredCupids'' is established in his first appearance to have been banished from the Homeworld when one of his experiments blew up the Department of Alchemy, taking several of its members with it. How intentional it was is unclear.
135	* [[spoiler:Cinder Fall]] of ''WebAnimation/{{RWBY}}'' was a victim of domestic abuse, enslaved by her so-called "guardian" and regularly tormented by her and her daughters. She secretly learned to fight from her mentor Rhodes in the hopes that one day she could escape and become a Huntress. Then her abusive "family" found out, went to punish her, and she finally snapped and killed all three of them. When Rhodes tried to bring her in for the murders, the betrayal broke her and she killed him too.
136	[[/folder]]
137
138	[[folder:Western Animation]]
139	* ''WesternAnimation/DannyPhantom'': [[WesternAnimation/TheUltimateEnemy Dark Danny]]. In an alternate timeline, Danny's friends and family were killed in an accident that Danny was partially responsible for. In his grief, Danny had his ArchEnemy Vlad Masters remove his ghost half... which then did the same to Vlad, merged with Vlad's ghost half, murdered the human Danny and went on a rampage for ten years. Dark Danny then tries to go back in time [[StableTimeLoop to ensure his own creation]] for no reason besides the fact he's an unrepentant monster, meaning this instance of the trope fulfills ''all four conditions of the trope''.
140	* Revealed by WordOfGod to be true of ''WesternAnimation/GravityFalls'''s BigBad, the interdimensional, omnicidal [[GreatGazoo all-powerful whackjob]] Bill Cipher.
