->"''No one walks away from torture unchanged; not the victim, nor the torturer himself. Never found torture worth the price, myself.''"
-->-- '''Zaeed Massani''', summing this trope up for both sides, ''VideoGame/MassEffect2''

Need someone to FaceHeelTurn, but the individual is uncooperative? No worries, just strap them to a table and go to town for a while. That's right, if you inflict enough pain on someone, they WILL be consumed by hatred and turn evil. Somehow. Sometimes {{handwave}}d by throwing the word 'brainwashing' around, but more often than not, it comes down to this simple theory: Pain is bad, so if you add enough pain to someone, they become bad!

Though you have to wonder... why does it tend to make them loyal as well? You'd think the newly evil victim [[TheDogBitesBack might turn their newfound lack of morality toward the guy that did this to them, preferably in a manner similar to what the villain did to them]]. StockholmSyndrome might factor in depending on how the torture was inflicted. In some cases, also, the torture was so horrific as to give the torturer a psychological hold on the victim, terrifying them into obedience. Also, sometimes the newly-evil victim ''isn't'' loyal to their torturer, but their ordeal has "opened their eyes" to the wretchedness of existence, birthing a StrawNihilist. However it works, you've now got a baddy with a grudge, lashing out at everyone near (especially if the "good" guys left them to be tortured in the first place).

As a literary device, it has two handy uses: It counts as a severe KickTheDog (or [[MoralEventHorizon worse]]) for the original villain, AND creates a tear-jerking [[TragicMonster Tragic Villain]].

Related to TeachHimAnger, BewareTheNiceOnes, BreakTheCutie, IControlMyMinionsThrough and possibly WhosLaughingNow. Can often be a StartOfDarkness or FreudianExcuse. It can also result in the creation of a WoobieDestroyerOfWorlds if done too seriously. A character with IncorruptiblePurePureness is resistant to this. RapePortrayedAsRedemption is roughly the inverse trope.

!!Examples (Read at your own risk, as many are spoilers)


* Ciel from ''Manga/BlackButler'' epitomizes this trope, going from an innocent, carefree child to a cold-hearted and icy one after being kidnapped and tortured on his tenth birthday. His dearest wish in life is to inflict merciless pain to those who did it to him.
* In ''VisualNovel/HigurashiWhenTheyCry'' the BBEG, [[spoiler:[[WoobieDestroyerofWorlds Miyoko Tanishi aka Miyo Takano]] ]] suffers from this. [[spoiler:After an abominable childhood in an incredibly extreme version of an OrphanageOfFear, she turns completely and utterly insane.]]
** Subverted with [[spoiler: Shion Sonozaki]] and the infamous "distinguishment". Whether it [[spoiler: turns into her StartOfDarkness or not]] depends on the arc.
** In a cross-series example, while [[spoiler:Rika]] eventually gets [[EarnYourHappyEnding a happy ending]], the [[spoiler:Rikas]] of the many [[AlternateUniverse alternate universes]] do not, and they eventually all culminate in [[spoiler:Bernkastel]], the BigBad of ''VisualNovel/UminekoWhenTheyCry''.
* Most of the Diclonius in (the necessarily shortened anime form of) ''Manga/ElfenLied''. Though at the very least the evil one that was on her tormentors' side had an ExplosiveLeash to keep her in check.
* Griffith of ''Manga/{{Berserk}}'' is a marginal example. While his torture did leave him permanently maimed, that by itself wasn't enough. After [[spoiler:his rescue by the Band of the Hawk, his heart broke when it became clear they weren't willing to carry around a mute, immobile lump of a former leader, but he thought he still had Casca on his side. It was learning that Casca not only agreed with the rest of the band on his uselessness, but was ''in a relationship with his former protege Guts'', that finally sent him past the DespairEventHorizon.]] The torture just got the ball rolling; it was the aftereffects that sent him over the edge.
* Done to Kaiser Ryo on ''Anime/YuGiOhGX''... except we never learn what the villain's motive was for doing it to him! Unlike the BigBad, he was neither a {{Cult}} leader nor soul stealer and didn't really have anything to gain from corrupting a teenager. Hell Kaiser isn't traditionally "evil", but he did become a much more vicious, ruthless character, as well as using the Underground's ElectricTorture devices against other duelists.
** He then tries this on his own little brother, and might have succeeded had Judai not intervened.
** AllLovingHero Judai later proves that a character with IncorruptiblePurePureness is, in fact, not immune from being driven evil by pain.
** Also in ''GX'', it was the combination of friction in space and the pain of the Light infecting Yubel that helped to drive her insane, and convinced her that this pain was Judai's love for her, fueling her entire "love is pain" philosophy.
* In the original ''Manga/YuGiOh'', [[AbusiveParents years of child abuse by his stepfather]] turned Seto Kaiba into the cold {{Jerkass}} that he is.
** Slightly less extreme example, but after the shift from the horror genre of the initial manga, creator Kazuki Takashi implied that Yami Yugi was aware of the 3,000 years passing in the Puzzle, which was responsible for his single-minded pursuit of punishing anyone who hurt Yugi after being initially released. [[CharacterizationMarchesOn He grows out of it.]]
* Riful in ''Manga/{{Claymore}}'' really likes trying to do this, although she isn't especially successful.
** It works ''in theory'' because she's only trying to provoke the Claymore's into releasing their full yoma power and becoming Awakened Ones; it's an almost completely physical event and what they want doesn't factor into it. Although Claymores fear awakening more than anything else, once they awaken they tend to immediately find [[EvilFeelsGood they enjoy the power and freedom from humanity]], which [[JustifiedTrope justifies this trope]]. Riful just tends to have bad luck; the first Claymore she tried it on died from the torture, the second worked but turned into an Awakened One too weak to be any use so she killed it and the third was rescued before her mind fully awakened.
* [[CreepyTwins Hansel and Gretel]] from ''Manga/BlackLagoon'' are a somewhat unique case in that they're children, and were ''raised'' under torture and abuse and implied rape as opposed to being decent people who were warped by it. So here it's less "Torture Makes You Evil" and more "Being Surrounded By Pain and Suffering Practicallly Since Birth With No Other State Of Being Known To You Other Than Pain Makes You ''Fucked Up''."
* Genkaku from ''Manga/DeadmanWonderland'' was revealed to have been beaten and raped by a group of bullies who hung around the temple when he was younger. It was definitely a contributing factor for making him AxCrazy and evil.
* Shiro Onijima of ''Manga/{{Pupa}}'' (not the anime, of course). As a child he was locked on by a MadArtist, claiming that love was his inspiration and pain was the purest form of love. The torture he endured involved a lot of "anger and pain," a room full of creepy worms, and the artist painting a picture inmediately after stripping him naked and whipping him. Shiro doesn't exactly turn evil, per se, although he starts believing that pain truly is love. And then he became the abusive father that often mutilated his son Utsutsu, because Shiro loved his son and wanted to show him that love.
* Konuma Ryuuko of ''Manga/WolfGuyWolfenCrest''. She's a nymphomaniac middle-schooler with what appears to be profound psychological damage from repeated rapes in her past, which made her a nihilistic sociopath.
* The supplementary materials to ''[[Anime/MobileSuitZetaGundam Zeta Gundam]]'' state that [[spoiler: Basque Ohm]], as a POW after the One Year War, was horrifyingly tortured by the enemy. It's also pretty justified, as he didn't join the side that tortured him--instead he takes out his rage on Zeon's former civillians.
* [[RivalTurnedEvil Sasuke]] from ''Manga/{{Naruto}}'' is possibly an example of this. Not only did his own beloved brother [[MoralEventHorizon slaughter their entire family]] he also [[ForcedToWatch made Sasuke watch it for what seemed like a three days]]. And after [[IneffectualLoner Sasuke]] was actually able to accept his teammates as his friends Itachi did it again to him for apparently no other reason than wanting him to suffer.
** Subverted with Kakashi, [[spoiler: whose resolve to take Akatsuki down was only ''strengthened'' after being tortured for days on end by one of their members.]]
** [[spoiler:Kurama shows signs of this. He lashes out at humans over the fact that they treat him as a beast, and the seal he was in while inside of Kushina involved having his limbs and tails chained down while he was impaled by a stake. It's also a distinct possibility that this is the same seal that was used to keep him inside Mito, which would mean that he was tortured for the better part of a century.]]
* Jellal from ''Manga/FairyTail'' turns into a Zeref worshipper after supposedly meeting his spirit while being tortured. [[spoiler:It's then subverted when Ultear reveals she just brainwashed him.]]
* In ''Anime/PuellaMagiMadokaMagica'' [[spoiler:all {{Magical Girl}}s are subjected to this by a cruel emotional universal EquivalentExchange counteracting their wishes, and eventually are warped into horrifying, [[ImAHumanitarian cannibalistic]] {{Eldritch Abomination}}s.]] This also happens to [[spoiler:Homura]] at a wholly different level in ''Rebellion''; even a nigh-unstoppable MagicalGirl like herself can only take so much psychological terror, and she endures a shitload of it [[spoiler:from the moment she first discovers how Witches come to be to the moment where she usurps Madoka and lashes out royally at Kyubey for many millennia's worth of acts of psychological terrorism against young girls the world over]].
* Basically Gatomon's back story in ''Anime/DigimonAdventure''. After years (or decades) of brutal servitude, she's the ruthless [[TheDragon lieutenant]] of a vampiric overlord.
* Torturing children into perfect soldiers was the goal of Kinderheim 511 in Manga/{{Monster}} but they only succeeded in producing monsters. So much so that after Johann turned the compound into the scene of his first real atrocity several of the survivors became his devotees. At least one of the others was a serial killer and Wolfgang Grimmer, while not evil, considered himself a monster.
* ''Manga/TokyoGhoul'' presents this as one of many themes on harmful cycles. It all started when a sadistic Investigator went off the rails and brutalized an imprisoned Ghoul until his victim was driven insane. This Ghoul, Yamori, would emerge from his captivity having taken on his tormentor's personality and became infamous for his hobby of capturing and torturing other Ghouls to death. Eventually, he would capture gentle protagonist Kaneki and subject him to over a week of brutal torture. After turning on his captor and escaping, Kaneki had himself taken on some of the brutal tendencies and {{Character Tic}}s of Yamori. This started his path from NiceGuy to an increasingly brutal and ruthless AntiHero.
* In many a {{Hentai}} this is turned into "being raped makes you a slut".
* In ''Anime/DragonBallSuper''[='=]s adaptation of ''Anime/DragonBallZResurrectionF'', Frieza ends up sparing Tagoma and instead uses him as his personal punching bag for four months as training. It's enough to break Tagoma's mind, turning him into a ruthless killer [[spoiler:and the perfect candidate for Captain Ginyu to hijack when he comes back into play.]]
* In ''Anime/CrossAnge'', Ange's little sister Sylvia had shown [[CorruptTheCutie her]] [[BitchInSheepsClothing antagonistic]] colors after torturing the former in public, though she is evidently a little conflicted over the matter the following night, and goes to her brother Julio for comfort. That is, until she accidentally barges in on Riza thralling Julio in secret, which leads to her being bound by the dragon. After Embryo frees Sylvia and captures Riza, the latter becomes Sylvia's next whipping victim as payback, [[ArsonMurderAndJaywalking on top of a list of lesser crimes]].
* In ''Manga/MekkoRarekko'', we have two examples, although one is much more extreme than the other.
** As an elementary student, Amanuma Shinichi felt that he had everything he ever wanted feeling that he was handsome with rich parents and that he was one of, if not the best student in the school. He was also a {{Jerkass}} towards Yamano Taishou, someone who looked up to him greatly for how cool he thought he was. Amanuma then [[spoiler: proceeded to bully as well as torture Taishou a lot in first grade and it got so bad that Taishou had to transfer to a new school.]] Because of that experience Taishou became a bit of a bully himself, but unlike Amanuma, he never went truly evil. So it's a subverted case with Taishou.
** Then we have Amanuma himself which is played completely straight. After middle school, his parents got him into a top middle school in the country, but he didn't think every much of it because he was already such a great student in his elementary school. But when he finally got into the top middle school with other top students, he realized that he wasn't as special as he really thought he was and that there he was just an average student. He tried very hard to catch up with the top students but he was unable to and he hated that. After turning in a student to a teacher for doing something bad he felt that it was the right thing for him to do. However [[spoiler: the students got back at him by burning the word ''pig'' onto his stomach. That experience lead to him dropping out of the top middle school and becoming a {{Hikikomori}} for a while. As a Hikikomori, he started to believe that everyone had a dark and ugly side they were hiding and that they just never show their true feelings. This lead to him having a much different outlook on life and he does turn evil and when he transfers to Buchi and Taishou's middle school, (in Taishou class, no less)) he pretends to be his friend again only to end up torturing him just like before and even making him into his SexSlave.]]
* In the {{Hentai}} ''Bible Black'', the BigBad explains that she wants to sacrifice the hero's LoveInterest to the Devil after she herself was the victim of botched human sacrifice years before, and was also gang raped by the [[{{Mooks}} hired goons]] of the covens new leader. She's only alive because, after killing the AxCrazy coven leader, [[DealWithTheDevil she agreed to sacrifice a virgin in exchange for not going to hell.]]
* Mostly averted by ''Manga/MyHeroAcademia'''s Principal Nedzu (a mouse who was experimented on for his high intelligence Quirk), but the Final Exam arc is a chance to get a little revenge on humans. Cue Mina and Denki getting the most sound defeat of the entire arc.

[[folder:Comic Books]]
* The Leader had to do this to [[ComicBook/BettyRoss Red She-Hulk]] in order to make her into a willing servant.
* In ''ComicBook/CaptainAmerica'', Crossbones uses tortures on his brainwashed girlfriend Sin, to bring her back to herself. It worked. Writer has to survive an attack of angry MoralGuardians, pissed off because right after being tortured Sin has sex with her oppressor.
** Somewhat understandable, since he did it to break her brainwashing. Also, her father, The Red Skull, also abused and tortured her growing up, Crossbones at least genuinely loves her and he's actually nice to her compared to how The Red Skull treats her.
* ComicBook/TheJoker attempts this on Commissioner Gordon in ''ComicBook/TheKillingJoke'' in true dramatic Joker style, complete with a CircusOfFear and an annoyingly catchy showtune. [[spoiler:It fails.]]
* ''ComicBook/TheWalkingDead'': Michonne doesn't exactly turn ''evil'', per se, after the Governor [[MoralEventHorizon repeatedly beats and rapes her]], although she does turn into a bitter, burned-out husk of a human being in a remarkably short span of time. It's worth noting that, whenever presented with the opportunity to actually kill the douchebag, she instead non-fatally, but painfully, wounds him; whether or not this is out of a simple desire for brutal revenge and making him suffer as he made her, or a subconscious want to keep him alive because of StockholmSyndrome is left up to the reader to decide.
* [[{{Transformers}} Unicron]] does this in order to acquire the services of Nemesis Prime; he finds a dead Optimus Prime somewhere in the multiverse, clones the corpse, and then horrifically tortures the clone for several thousand years. It works.
** Unicron goes the extra mile. He tortures his thralls to the point where merely ''existing'' is unbearable agony to them. Which makes his [[OmnicidalManiac philosophy]] appealing merely because it'd be an end to such pain.
* An almost literal example in the Superhero/Police drama ''ComicBook/{{Powers}}'', where Deena is being repeatedly zapped by the energy powers of a man called "The Bug." His powers are apparently both contagious and addictive, since he plans on getting her hooked on it, but she jams his hands down his throat to blow him up and absorb the rest of his powers, proceeds to melt the rest of the gang, and has secretly murdered at least a couple of people since then; the powers seem to be having an effect on her mind, because when she fried her ex-boyfriend who stabbed her in the back, she entered a fugue-like state and didn't emotionally react until well after she had disposed of his body.
* ''Franchise/{{Batman}}'': Black Mask was already a murderous gangster, but when he was lit on fire and left for dead, the resulting burns and further disfigurements got him interested in the subject of torture.
* Likewise, Black Mask tortured ComicBook/{{Catwoman}}'s sister, Maggie, [[ForcedToWatch forcing her to watch]] as he tortured her husband and ''force fed her pieces of him''. After breaking out of her catatonic state, she's become Sister Zero, a religiously-motivated villain who believes that her sister's soul is in thrall to a "cat demon," and she's going to "exorcise" it even if she has to kill Selina to do so.
* In ''ComicBook/XMen Noir: Mark of Cain'', Thomas Halloway is kept in "Project: Wideawake" by Professor Xavier as long as he withholds information from him. Project: Wideawake employs a mixture of blindingly bright lights and deafening sirens to deprive the subject of sleep. After about a week of the treatment, Tommy snaps. He starts acting like, and insisting he be referred to as, his dead twin brother Robert - a sadistic lowlife. [[spoiler:He's faking.]]
* Cinder from ComicBook/{{Deathstroke}}'s ''[[ComicBook/TeenTitans Titans]]'' was sexually abused by a super villain called Nursery Crime when she was a child, some time after her entire family died in an explosion. With her heat powers she goes after child molesters and rapists, and is also suicidal because her powers prevent her from dying. [[FlatCharacter That's her entire character.]]
* In ''ComicBook/FantasticFour'' #600, it's revealed that this apparently happened to [[spoiler:Johnny Storm.]]
* Two-Edge from ''ComicBook/ElfQuest'' is the product of an insane female elf and a troll she once seduced. He grew up neglected and tortured by his mother, and his father died shortly after he was born. His mind is broken pretty quickly and he spends most of the series as a villain, until Leetah finally manages to heal him after approximately 15000 years.
* ''ComicBook/DeadNoMoreTheCloneConspiracy'' sees this as part of its backstory as [[spoiler:this time, the Jackal is [[ComicBook/ScarletSpider Ben Reilly]], having being resurrected, then killed and resurrected 27 more times.]]
* The origin of the recent ComicBook/GuardiansOfTheGalaxy villain Talonar. [[spoiler:He's actually Nova's missing brother Robbie who remained unaware of the final outcome of ComicBook/TheThanosImperative, outside of "we won." He traveled to Xandar alone to try to jumpstart the Nova Force, but is instead captured and tortured for information by members of the Fraternity of Raptors. They later lock him into a helmet which isolates his senses and severely slows his sense of time making minutes seem like years. This coupled with his lack of knowledge of Richard's supposed death made him feel like his brother and allies abandoned him. When he was given the choice to either die with honor as a member of the Nova Corps or extract revenge as a Raptor, Robbie chose the later.]]

* In ''Fanfic/ChildOfTheStorm'', there's the classic case of the Winter Soldier, who suffered about seventy years of repeated MindRape, the ante being upped every time he showed signs of straying from his programming. Also, Natasha, though marginally less severely. In both cases, it was by the Red Room, and in the Winter Soldier's case, latterly by HYDRA as well.
** In the sequel, this happens to [[spoiler: Harry]], also at the hands of the Red Room. Brutal psychic torture and [[spoiler: an escape plan that went wrong]] resulted in the Red Son, the second, upgraded iteration of the Winter Soldier, a LivingWeapon who helped subjugate half a continent. [[spoiler: Harry]] getting control of his body back only made it worse, resulting in his snapping and taking revenge as [[spoiler: the Dark Phoenix]]. And even after he's talked down, coming back to himself, his horrific PTSD means that he's much sharper, more bitter person than before, with a terrifying HairTriggerTemper.
* In ''{{Fanfic/Popped}}'', Pinkie Pie develops some serious PTSD after being rescued from Pokey.
* In ''Fanfic/{{Stray}}'', part of the {{Antihero}}'s backstory involves an attempt by the setting's AncientConspiracy to [[InvokedTrope invoke]] this. The AncientConspiracy didn't want to risk their TykeBomb spy/assassins developing any [[ConflictingLoyalty inconvenient attachments]], so they attempted to instil [[TheSociopath sociopathic]] tendencies in their future operatives by means of an abusive upbringing. It doesn't entirely work - Adamska can be ruthless, and he has [[FutureMeScaresMe the potential to be a lot worse]] - but he is capable of genuine emotional attachment.
* In ''{{Fanfic/Misunderstandings}}'', while "evil" might be stretching it, the [[WesternAnimation/MyLittlePonyFriendshipIsMagic ponies]] fear that the human protagonist, Peter might fall under this trope. His first encounter with ponies was being captured by ponies and put on display in a CircusOfFear as a mysterious monster, and during his downtime, the ringmaster, Big Top regularly abused him and the other "exhibits." One of the other creatures held prisoner, a minotaur, plays this trope straighter, as he tries to kill Peter when he escapes and tries to kill their tormentor. Twilight attributes this behavior to something called [[StockholmSyndrome Stockgroom]] [[CallARabbitASmeerp Syndrome]].
* ''[[Fanfic/ANewChanceSeries A New Chance for Adventure]]''. The way Slave Pokemon are created. Since birth, they are conditioned into blindly obeying the one who holds their Pokeball. By their adulthood, they have all emotion stamped out, and will obey their trainers toward any extreme.
* As ''Fanfic/AshesOfThePast'' shows, one way [[BrainwashedAndCrazy Shadow Pokémon]] are created is by torturing them until they break. The process is accelerated by capturing them in a [[Anime/Pokemon4Ever Dark Ball]], [[spoiler: and not even Ash's Pikachu is immune]].
* In ''FanFic/TheFifthAct'', Cloud was already growing unstable when he started to believe that the timeline didn't change despite [[PeggySue his efforts]]. Being experimented on by Hojo, unbalanced by the [[LukeIAMYourFather truth of his origins]] and seeing Sephiroth burn down the Shinra Mansion allows [[spoiler: Jenova to possess Cloud in Nibelheim.]]
* In ''Fanfic/HopeForTheHeartless'' (''TheBlackCauldron'' fanfic), [[SycophanticServant Creeper]] is revealed to have lived his [[FriendlessBackground entire life]] serving [[BadBoss the Horned King]] and being bullied by the [[OurLichesAreDifferent lich's]] soldiers. That's why he's a [[DirtyCoward cowardly]] [[{{Jerkass}} bully]].
* Poor [[spoiler: Ezra Bridger]]in ''Fanfic/EzraLost'' is revealed to have fallen victim to this trope around the end of the story. [[spoiler: Luckily, he's not beyond the point of no return yet]].
* ''FanFic/DungeonKeeperAmi'': Explains why torture turns prisoners to the torturer's side in Dungeon Keeper setting by having the dungeon hearts be a minor MindControlDevice with Keeper minions.
* ''[[https://www.fanfiction.net/s/12629672/1/The-Hands-of-Fate-Invasion The Hands of Fate: Invasion]]'': On Earth-2, Metahumans have been officially declared enemies of the state and stripped of their rights. Those captured are locked up without a trial, rendered sterile (the men through chemical treatments, the women have ''their ovaries removed''), and brutally experimented on. Unsurprisingly, once Zoom frees them they quickly rally to his "cause" and start fighting back against a society that has abused them.

* ''Film/VForVendetta'': For given quantities of Evil, we have this back and forth:
-->'''V''': [[MotiveRant What they did to me was monstrous.]]\\
'''Evey''': [[ShutUpHannibal And so they created a monster?]]
** The ShutUpHannibal is actually used ''for'' V, because Evey is convinced he isn't a bad person.
* ''Franchise/{{Saw}}'': This happens to several characters in the sequels. Most prominently, [[spoiler:Amanda and Gordon.]]
* In the film ''Film/LawrenceOfArabia'', Thomas Lawrence becomes an AxCrazy, ruthless BloodKnight after having been tortured by the Turks... ''as a deserter''.
* In the film ''Film/FleshAndBlood'', the innocent virgin DamselInDistress gets kidnapped by a group of bandits and gang raped. She then joins their crew and merrily takes part in their excursions.
** ... except she was [[FilleFatale never all that (sexually) innocent]] and participated out of a combination of [[StockholmSyndrome Stockholm Syndrome]] and a desire to avoid further abuse by fitting in - so, a [[JustifiedTrope relatively realistic application of the trope.]]
* BigBad [[spoiler:Carson Dyle]] in ''Film/{{Charade}}'', who was abandoned by his wartime comrades after being badly wounded, and suffered months in a prison camp without any treatment. After he gets out, he's only living to get his hands on the money they stole together.
* In ''Film/{{Super 8}}'', it's eventually revealed [[spoiler:that the monster is an alien who's been experimented on and tortured by the military for decades, to the point that it views all humans as threats and is willing to [[KillAllHumans kill them all]].]]
* ''Film/RiseOfThePlanetOfTheApes'' : Koba, Koba, Koba. [[Film/DawnOfThePlanetOfTheApes The following decade just makes him worse]] [[spoiler:and he's willing to start a war because he can't let go of the memory of [[AnimalTesting being a test subject]]]].
* ''Film/XMenFilmSeries''
** This sums up Erik Lehnsherr's (who later becomes Magneto) backstory in ''Film/XMenFirstClass''. The torture he endured involved a lot of "anger and pain," a room full of creepy sharp instruments, and there was a flash of something akin to sadistic dentistry, but it's the emotional torment that seems to have broken him.
** Implied in Mystique's backstory told in ''Film/XMenDaysOfFuturePast''. After [[spoiler:assassinating Trask to avenge her fellow mutants, she is taken captive and experimented on, with her DNA being used to create the BadFuture Sentinels. The [[DespairEventHorizon experience likely resulted]] in her transformation into the remorseless killer we see in the original trilogy]].
* The point of ''Film/SaloOrThe120DaysOfSodom''. [[spoiler: Given that refusing to be turned evil means being gruesomely tortured and executed, although none of the victims know this.]]
* In ''Film/{{Skyfall}}'', Silva was captured and tortured for five months, to the point where he tried to commit suicide only for his CyanidePill to end up horribly disfiguring him but leaving him alive. What really drove him over the edge, though, was the realization that [[spoiler:[[ParentalBetrayal M betrayed him]] and left him to this fate. The pain he suffered because of her is the source of his RoaringRampageOfRevenge]].
* The Cenobites from ''Franchise/{{Hellraiser}}'' were once human, but years of torture in Hell have turned them into monsters. [[HumanoidAbomination Rather literally]].
* In ''Film/TheDarkKnight'', Harvey Dent becomes Two-Face via an extremely well-applied version of this; after [[spoiler:killing Rachael Dawes]] and burning off half his face, Joker comes to Dent's bedside with a gun and tells him that since the system couldn't prevent those things, he should leave things to chance. He then gives Dent his coin and suggests a game of RussianRoulette...
* In ''Film/TheBourneUltimatum'', we get glimpses of the induction process Treadstone (and presumably Blackbriar) agents undergo. Specifically, Jason is told to murder a man, sitting in a room with a bag over his head, and every time he refused Jason had a bag put on his head and he was severely punished, vis-à-vis solitary confinement and waterboarding among other methods, until he finally broke and killed him. To twist the knife further it seems that Jason, who volunteered, initially seemed to think the test was to not kill the man, given how soldier-like he took the orders.
* A possible explanation for Ajax and Angel in ''Film/{{Deadpool 2016}}'', choosing to work for the organization that tortured them into mutation.
* In ''Film/Frankenstein1970'', it is strongly implied that is the torture he received at the hands of the Nazis that tipped Victor over the edge into obsession and insanity

* The Japanese ''[[http://yokai.com/inugami/ inugami]]'' is, in traditional folklore at least, exactly this trope; in the process of creating it, the summoner (called an ''inugami-mochi'') is said to literally [[KickTheDog torture a dog]] not only to death, [[UpToEleven but also]] ''[[FateWorseThanDeath post-mortem]]''. This creates a powerful entity that can be forged into a [[CanineCompanion loyal servant]] willing and able to commit any kind of sin on its creator/master's behalf up to and including murder, curses, or [[DemonicPossession bodily possession]] - at least, so long as you maintain and retain its mummified head and "don't seriously mistreat it". Would-be inugami-mochi [[EvilIsNotAToy should beware]] though: as [[GoneHorriblyRight powerful, anger-prone spirits]] they have a tendency to pull a sometimes very ''literal'' TheDogBitesBack... and for [[MoralEventHorizon obvious reasons]], the Japanese government as far back as the Heian period outlawed the practice, complete with permanent shunning for anybody even ''suspected'' of having tried to use it against another person, a punishment including ''continued'' shunning of any and all of the suspected inugami-mochi's ''future children''. Little wonder that these sorcerers were said to be "secretive".
* Thanks to some of the beliefs of Shinto and Buddhism, a number of Japanese ghost stories feature elements of this; the difference being that it's [[FateWorseThanDeath not just bodies]] that can be tortured, as a ''soul'', too, can be driven to downright malicious madness that lasts even after death; often this is caused by the horrific circumstances of the death itself. Case in point: the folklore that served as inspiration for ''Film/TheGrudge'', which involved a ghost being so unable to rest that they [[spoiler:would start to kill everyone who so much as set foot in the house that they died in, with the only cure for the resulting curse on the house being to burn it to the ground]].

* Averted in the ''Literature/{{Hurog}}" novels with a couple of characters, but most notably Oreg, who spent his "life" magically bound to generations of owners of the eponymous castle Hurog, not all of whom were kind to him. There was no corrupting him - he is even nice to Ward, who looks like his father. Then there is Ward, who didn't become one bit evil, even though his father was abusive and at least once almost killed him.
* In ''Literature/TheSilmarillion'' (a sort of prequel to ''Literature/TheLordOfTheRings'' and ''Literature/TheHobbit''), it is revealed that the original orcs in Creator/JRRTolkien's Universe were created thousands of years ago by Melkor, an allegorical version of Satan, who tortured elves he captured endlessly until they went mad and became monsters. The fact that elves in Tolkien's mythos are immortal makes this an example of WhoWantsToLiveForever, as well.
** Tolkien was rather ambivalent about this detail; his notes made it clear that he didn't want it to be canon, and it also raises a number of thorny questions about with his mythology. For example, why haven't the number of orcs decreased over time as the originals were killed off? Orcs as corrupted elves also didn't mesh with his cosmology; would dead orcs go to the Halls of Mandos, where normal elves are taken after death, or would they share the fate of Men? The deeply Catholic Tolkien was conflicted over these, along with the concept of AlwaysChaoticEvil, which is why he didn't publish ''The Silmarillion'' before his death.
** Averted with the AntiVillain Maedhros: his being tortured (hung by his right hand from a cliff for a couple of years) only made him more badass. Though he did become something of a villain, it was for different reasons.
** Also averted with Húrin. After watching what Morgoth's curse did to his family, did he set out on a RoaringRampageOfRevenge? No, he killed exactly one dwarf - Mîm, who betrayed his son to the orcs and was arguably asking for it. Then he bitched out his son's foster-father and left. Things went to hell anyway...
*** Only in the published ''Silmarillion''. In ''Literature/TheHistoryOfMiddleEarth'', he sparks a civil war among the Haladin and orchestrates the death of their chief and his remaining family members out of the belief that they failed to protect his children and thrust his wife out to die. He then ends up killing the Haladin who followed him in a petty fight over treasure, and is only stopped from causing more damage by Melian telling him that he isn't helping anyone. [[DrivenToSuicide Then he kills himself]]. This might actually be a case of being tortured makes you crazy instead, which would certainly be justified after what happened to him.
** A straight example would be Maeglin- although he was definitely jealous of Tuor beforehand, it was only being captured and tortured (or the threat of it at least) by Morgoth that caused him to spill the location of Gondolin and try to kill Tuor and his son, Eärendil.
** In ''Literature/TheLordOfTheRings'', Gollum was evil to begin with, but after being tortured by Sauron he became worse.
* ''[[Literature/NineteenEightyFour 1984]]'' - you only need fear and pain to break a rebel into an obedient citizen who finds HappinessInSlavery.
** Questionable. Winston's torture doesn't really turn him evil, per se; he just becomes a 'good citizen'. In fact part of the means used to break his self esteem and conviction is reminding him that as a rebel he promised to do anything, commit any atrocity, in the name of the Brotherhood of Freedom, the possibly non-existent LaResistance. You could maybe argue that obedience is evil, but whether that's true or not is kind of the point of the book ("Is a lunatic a minority of one?"). Either way, the torture and its effects are definitely not {{hand wave}}d but [[JustifiedTrope explored in great detail]] (about half the book).
** More to the point, was Winston a good guy to begin with? Sure, Big Brother is clearly a bad guy, but Winston doesn't really appear to be any better than anyone else -- just a bit more independent.
* Mord Sith from the ''Literature/SwordOfTruth'' books, but although one described what happened, it never really got into why it worked (something about the most innocent can be turned, but that's still not getting into it). It just did.
** It was explained as 'Years of horrific torture designed to break someone, and then keep torturing them and only stop if they torture other people for you.'
** It also probably helps that the people Mord-Sith come from have grown up ''worshiping'' and learning blind obedience to the Mord-Sith's master. As terrifying as the prospect is, the girls chosen have already had it hammered into them that this is a holy calling and their destined fate, and are partially picked for a lack of innate resistance and a natural desire to please. StockholmSyndrome is far more powerful when you ''start out'' seeing your captors as compassionate teachers and ideal role models.
** They take the sweetest, most eager-to-please girls at a very young age, torture them elaborately and horrifically, physically and psychologically, until they will do anything for their teacher; until they become so used to pain that they actually get off on using the weapon which causes anyone it touches - including the wielder - unendurable pain; then they are forced to watch as their mother is tortured to death, and then to torture their own father to death. Oh, and it's considered commendable if they thereafter avenge themselves on their masters by torturing them to death. Anyone who is pushed that far without dying is bound to go a bit insane.
** The loyalty thing is explained by a magical connection they have to whoever the current Lord Rahl is - even if they don't necessarily like it.
* ''The Scorpion Signal'', an espionage novel by [[Creator/EllestonTrevor Adam Hall]]. The protagonist Literature/{{Quiller}} is sent to track down a RogueAgent who was tortured by the KGB, and nearly gets killed because he fails to consider just how much torture can change a man. Like making him willing to kill a former friend [[spoiler:when he interferes in his plot to assassinate the Soviet Premier.]]
* In ''Chosen'', the Antichrist starts out as an AntiAntiChrist... until his "dad" and some demons torture and rape him for several years. Then he becomes a proper Antichrist. Somehow.
* Happens to several characters in ''Literature/TheFirstLaw'', although torture doesn't always ''make'' them evil in a direct cause and effect:
** Inquisitor Glokta, one of the main protagonists, was a dashing MasterSwordsman and all around "golden boy" until he was captured in battle and horribly tortured, leaving him a total physical wreck. After the war, he became a TortureTechnician, and while [[DeadpanSnarker amusing to read about]] and known for occasionally petting the dog, he's still cruel and generally devoid of empathy. Somewhat subverted in that he wasn't really a great guy prior to the torture, so in a way, it just brought out the "real him".
*** Glokta's example is deconstructed as the story goes on; he was raised to be a soldier and nothing else, and when he was crippled, he had no other skills to fall back on... but he ''did'' have lengthy experience in knowing how to break a man, making his turn to the Inquisition [[PragmaticVillainy quite sensible.]] He's also unique in that he becomes more compassionate instead of less through the trilogy, making use of ExactWords and BotheringByTheBook to spare the innocent as far as he can. This is most notable when he [[spoiler: marries Ardee and claims her unborn child, Jezal's bastard, is his]]. This effectively saves both their lives; he gets away with it because he had promised to "deal with" the "threat to the state" they posed, and even then knows he is skating on terribly thin ice.
** Salem Rews, a BigFun merchant and former friend of Glokta is brought before him, and Glotka has him beaten and threatend with torture to get him to confess to largely trumped up charges. Rews is then sent to a penal colony, and shortly after arriving, is horribly burned in an accident. He eventually comes back for vengeance on Glokta, but is persuaded to become Glotka's partner and in a later book, he's shown as the superior officer of the guy who ran the penal colony in which he was once a prisoner.
** Shivers, a protagonist of the spin-off novel ''Literature/BestServedCold'' is a BarbarianHero trying to be a good person. Over the course of the book, he becomes increasingly morally compromised, and after he's captured and [[EyeScream has his eye burnt out]], he becomes a vicious BloodKnight and pulls a FaceHeelTurn. However, he mellows out a bit in later books.
* ''Literature/XWingSeries'': Ysanne Isard, Director of Imperial Intelligence, has a secret prison called the Lusankya. She captures people, brainwashes them, and turns them into unwitting agents, letting them free afterwards to go back to the New Republic, completely unaware of what's happened to them [[ManchurianAgent until they find themselves doing her will]]. The process of converting people is never detailed in full, but it does involve torture. Tycho Celchu went through this and remembers being in that prison when he's let go. When he reports back he's suspected to be one of the unwitting agents even though he remembers being there. [[spoiler:But he was [[IncorruptiblePurePureness immune]].]]
** it's also interesting, in that 1. It's shown that there's more to it then torture, including simulations, drugs, and such. (They start getting rewarded for being evil/doing as the torturer says)...and it's made a point that there are a LARGE amount of people it doesn't work on...who are being kept in the prison.
** In ''Rebel Force'' a different Imperial has a method for turning people into emotionless assassins, which involves torturing them vigorously while he wasn't in sight to induce StockholmSyndrome, then [[CriminalAmnesiac erasing all of their old memories]]. It's suggested but left up in the air that his best assassin, X-7, may have used to be one of the heroes of ''Last of the Jedi''. Late in the series he gets his hands on Luke Skywalker, but Luke resists and plays along.
* ''Literature/LegacyOfTheForce'': Jacen Solo does this to Ben Skywalker, in an attempt to turn him to the dark side, and make him his first apprentice.
** Speaking of Jacen Solo, his time as a prisoner of the torture-happy [[Literature/NewJediOrder Yuuzhan Vong]] is widely held to have contributed to his own eventual turn to the dark side.
* [[spoiler:Thomas Raith]] in the eleventh book of ''Literature/TheDresdenFiles'', is hideously tortured by the Skinwalker. While he had spent the previous books finding ways to sate his hunger without harming anyone, this event makes him reconsider whether it's worth it. In his next appearance, he's as good and friendly as he had been, but still decidedly well-fed. In the following book, he has apparently undergone a sort of hunger strike[=/=]HeroicBSOD after [[spoiler:Harry's death]].
** [[spoiler: Since the woman he's in love with has figured out a way around the whole 'I can't touch you' thing he no longer has any need to feed from anyone else, rendering the whole thing moot anyway.]]
* Questioned in ''The Cursed'' by Creator/DaveDuncan, though not exactly lampshaded. The response is that this does indeed work if you don't only use torture, but combine it with a system of mental conditioning (the nature of which is never actually explained.)
* Folgrim of ''[[Literature/{{Redwall}} The Legend of Luke]]'' suffered a variation. He was tortured and blinded in one eye by vermin, and this caused him to become insanely violent and unstable, but his violence was directed towards vermin specifically. Since they're AlwaysChaoticEvil the good guys have no problem with him killing them, but when he starts to ''eat'' them...
-->"Nice fire, I likes a good fire!"
* Creator/NeilGaiman's short story [[http://holdinghandswithhades.edublogs.org/seven-deadly-sins-part-7-the-others-by-neil-gaiman/ "Other People"]] in which a businessman is tortured by a demon, first physically with two hundred and eleven different devices, then mentally with all his lies and misdeeds and their consequences over and over until he can no longer lie his way out of them. When it is done, the demon is gone, and [[StableTimeLoop a businessman comes in]]...
* A.C. Crispin wrote ''Literature/TheHanSoloTrilogy'', which covers [[Franchise/StarWars Han's]] life from his teenage years up to the start of [[Film/ANewHope the first Star Wars movie]]. Many characters from stories that take place later in Han's life appear in this series, one of whom betrays Han [[OnlyInItForTheMoney for money]] in ''ComicBook/DarkEmpire''. In Crispin's books we find that he used to be a decent man, as good a friend of Han's as Lando was. Then he got captured, tortured, and crippled for life. In the third book we see that the experience has made him quite bitter. When Lando and Han visit him to see if there's anything they can do to help, at first he doesn't acknowledge them. Finally, he gives them a look that tells them to get out and leave him alone. Perhaps he wasn't quite ''evil'' at the time, but he was certainly [[StartOfDarkness starting down the path]].
* Murtagh from the ''Literature/InheritanceCycle'' started out as Eragon's friend and well-intentioned {{antihero}}, but his capture and MindRape (and who knows what else) at the hands of [[BigBad Galbatorix]] turned him bitter, power-hungry, and rather unstable. Galbatorix ensured his loyalty by using Murtagh's true name (which gives total control to the one who uses it) and forcing him to swear various oaths that he was magically bound to follow. Once freed, Murtagh seems to be a basically okay guy again, so you decide if he was actually bad.
* Volkov, Russian chief vampire from Alexander Yang's Literature/MidnightWorld series, became a victim of extremely unjust court in a very young age. He was cruelly tortured to extract the evidence against his father, and almost died, when his Master showed him the way to survival and revenge.
* Inverted in ''Literature/ASongOfIceAndFire'' with [[spoiler:Theon Greyjoy. Previously a definite SmugSnake, the brutal torture he receives at the hands of the series' resident BastardBastard leaves him frail both physically and mentally and, while not a good person, leagues away from the outright villain he'd been before. And it's only after all this that he commits his first truly selfless act by saving Jeyne Poole.]]
** It's also a subversion, because the initial purpose of the torture was to turn Theon from a bumbling, pathetic excuse for a villain into a loyal servant to the truly horrifying Ramsay Bolton.
* Myth/NorseMythology: The original god Loki in the ''Literature/{{Edda}}''. (Not to be confused with the Loki in Marvel's superhero comics and movies.) His origin is unclear, as he is neither one of the Aesir nor a Vanir, but becomes bloodbrother to Odin and friend of Thor. Loki, the shapeshifting god of the hearthfire, starts out as a trickster who causes mischief but often gets the gods of Asgard out of a tight corner. This changes after he has to flee from the halls of Asgard and hide on Midgard (Middle Earth), although the reasons given vary according to the various tales in the ''Literature/ProseEdda'' and the ''Literature/PoeticEdda'':
** One version claims Loki, the father of the wolf Fenrir, the Midgard Snake, and of Hel, the goddess of the Underworld, was feared for his prophesied role in the coming Final Winter, which is why the gods wanted to imprison him (despite the fact it was also prophesied that he would free himself in time for the final battle).
** Another tale paints Loki as indirectly responsible for the (prophesied) death-by-mistletoe of Baldur, god of light, and the subsequent unsuccessful attempt to resurrect Baldur from the Underworld, which set in motion the events of ''Ragnarök'', the Norse apocalypse.
** The ballad "Lokasenna" (Loki's taunting of the gods) from the ''Poetic Edda'' however describes how the sea god Aegir aroused Loki's ire by holding a big feast at his hall and inviting everyone in Asgard except Loki; when Loki crashed the party and started angrily taunting the assembled gods and goddesses, Loki not only insulted several of them with sarcastic banter about their various not-so-brave deeds but also bragged how he bedded many of the goddesses while their husbands were away. Enraged, the gods tried to kill Loki, who had to flee. When the gods finally captured him, they transformed one of Loki's sons into a raging wolf who tore the other son apart in front of Loki and Loki's Aesir wife, then used the sons' entrails as chains to bind Loki to a boulder in a cave until he couldn't move, ''then'' they hung a poisonous snake over his exposed face that drooled acidic poison into Loki's eyes day and night; after the gods had left Loki's loyal wife spent days and nights holding up a bowl over Loki's face to catch the poison, but whenever she went outside to empty the bowl, the agony of pain made Loki tear madly against his chains (which caused earthquakes). He manage to free himself in time for Ragnarök and joined the tribes of giants, his own monstrous children, and the ship of the dead that came sailing from Helheim in their battle against the gods of Asgard. - Which makes this trope OlderThanPrint, depending on if you believe Loki was always secretly evil or if his mind snapped during the torture.
** Loki could be kind to his followers at times, as told in the very few remaining stories about him. So he's not always depicted as evil.
* [[spoiler: Peeta]] was tortured and [[BrainwashedAndCrazy brainwashed]] by the Capital in ''[[Literature/TheHungerGames Mockingjay]]''. While he wasn't exactly [[WoobieDestroyerOfWorlds evil]], his vision of [[IRejectYourReality reality]] was so screwed that he [[spoiler: tried to kill Katniss.]]
* This is what seemed to have happed with Dr. Edith Marlok in ''{{Literature/Suspicion}}'' by Swiss author ''Friedrich Dürrenmatt''. According to her, she’d been once faithful young communist who believed in a better world. After being sent to concentration camp Stutthof and working with BigBad Dr. Emmenberger she became a cynical, indifferent, misanthropic morpinhe-addict.
** This is averted however with Gulliver, who was also tortured by Emmenberger and had been in many concentration camps but became a VigilanteMan and NaziHunter instead.
* Discussed but ultimately {{Averted}} in ''Literature/TheStormlightArchive''. Kaladin's repeated mistreatment at the hands of various lighteyes has him an inch from doing a HeelFaceTurn and going on a RoaringRampageOfRevenge, but he ends up having a HeelRealization instead.
** In the second book of the series, however, this seems poised to be played straight with Kaladin's friend Moash. As of the third book Moash seems to have taken [[JumpingOffTheSlipperySlope a flying leap off the slippery slope]] and become a villain.
* [=FitzChivalry=] toys with this in the third trilogy of the ''Literature/RealmOfTheElderlings''. He notes that he was once tortured to death ([[NormallyIWouldBeDeadNow although it didn't stick]]), and it left him with an occasional sadistic streak; his fight-or-flight response got ramped up, and although [[BewareTheNiceOnes he always wants to run...]]
* ''Literature/HorusHeresy'' has [[BlackSheep Konrad Curze]] try to invoke this on [[WhiteSheep Vulkan]] - Curze believes that every man is evil at heart and he intends to prove it on his brother. Ultimately, [[spoiler:it fails, but Vulkan goes completely insane.]]

[[folder:Live-Action TV]]
* ''Series/{{Homeland}}'': Whether or not this applies to Nicholas Brody is an important and recurring plot point.
* In the US adaption of ''[[Series/HouseOfCards House of Cards]]'', Claire seemed to place more blame on herself for being raped years ago than on the rapist himself.
-->"Every time I think of her, pinned down like that, [[ThatManIsDead I strangle her]], Francis, so she doesn't strangle me."
* ''Series/{{Supernatural}}'': Hell works along this premise. To the extent that once they torture away enough of your previous identity you become a demon, which in this setting are AlwaysChaoticEvil, although while all demons are stated to have been once human it's unclear whether all the damned make it all the way to demon. [[spoiler: Dean takes thirty years of torture in the season break he spends in Hell, before he cracks and starts torturing other souls, and enjoying it because it's not being tortured. He blames himself for this intensely. Also notable, they gave him to Hell's chief torturer for most of it; he's a tough cookie, but he gives himself no credit.]]
** Soon after the angels want Dean to use the "expertise" he learned in hell to interrogate a demon. Dean vehemently refuses, saying it will [[JumpingOffTheSlipperySlope shove him right off the slope with no hope of coming back]], which almost makes this a case of [[InvertedTrope Torturing Makes You Evil]].
--> '''Dean:''' If I go in there and do it, [[MoralEventHorizon I won't be the same person when I come out.]]
** Part of the transformation may be when you start torturing others. [[spoiler:Dean]] at least claims this is because if you start torturing others, they stop torturing you. And by that point he just desperately wanted the pain to end.
** Another example [[spoiler: Anna was one of the few good angels, before she was captured and tortured by other angels. She describes it as the same torture as hell, but twice the self-righteousness. She comes out of it little crazy and is now fighting against Sam and Dean, but comes off as a WellIntentionedExtremist]].
* ''Series/TwentyFour'' used a more realistic version of this: Season Three BigBad [[spoiler:Stephen Saunders was on the same team with Jack Bauer that went into Kosovo for a covert mission; Jack was assumed to be the only member of the team who survived, and Stephen was left for dead. His disillusionment at being abandoned to the enemy is the driving force behind his actions in Season Three]].
* [[spoiler:Gray]] in the ''Series/{{Torchwood}}'' series 2 finale. Jack lost him while fleeing some very evil aliens who captured and tortured him for years and years. He survived with no conscience and a mega-sized grudge against his big brother for failing him. So he killed a lot of people.
* In ''Series/{{Firefly}},'' this can happen to you at the hands of the Reavers. Even though the original Reavers were created by a drug that made them go berserk, they can produce exactly the same effects in other people simply by making people ''watch'' them do their Reaver thing. Apparently, it's a form of Post Traumatic Stress Disorder.
** Since the drug is inhaled, the first thing the Reavers do is exchange atmospheres with their captured ships, and most crews don't seem able to put up much resistance, it's likely they're dosing crews with the same drug that transformed them. In the series proper, though, no explanation is given and psychological damage is blamed.
* In ''Series/{{Charmed}}'', [[spoiler:Gideon]]'s torture of [[spoiler:Wyatt]] in an alternate timeline turned him evil. Fortunately, they fixed the problem.
** It's implied that this happened to [[spoiler:Christy, Billie's sister]] since she was kidnapped by demons when she was six years old.
* In ''Series/StargateAtlantis'', the Wraith can do this to turn the boldest humans to lawful servants. They did this to [[spoiler:three Satedan friends of Ronon]] and later [[spoiler:even Ronon himself]]. It also helps that the victims become addicted to the enzyme used in feeding, which makes the one addicted exercise extremely poor judgement.
* Though nearly all vampires in ''Series/BuffyTheVampireSlayer'' are evil, Drusilla is more fond of slow torture than most, probably because of the way she was tortured extensively by her sire Angelus before she was turned. Her torture also made her very, very unhinged.
* Allan-a-Dale in the BBC's version of ''Series/RobinHood'' was captured by Guy of Gisborne and tortured into becoming TheMole. There were a few mitigating factors including the fact that Allan was already dissatisfied with the lifestyle of an outlaw, but when he's discovered, he uses the torture as his excuse.
* ''Series/TheColbertReport'' once used this in a bit of circular StrawmanPolitical InsaneTrollLogic: if you're mistaken for a terrorist who hates America and consequently imprisoned in Gitmo and subjected to EnhancedInterrogationTechniques, you'll soon hate America -- and therefore, we'll have to imprison and torture you!
* ''Series/VeronicaMars'': [[spoiler:MY NAME IS CASSIDY!]]
* ''Series/LostGirl'': [[spoiler:Bo's mother after being tortured by the Dark Fae]]. Though this overlaps with being tortured makes you crazy.
* ''Series/LegendOfTheSeeker'' loves this trope, much like the books it was based on. The Mord'Siths' strength and devotion to eeeevil comes from having the good tortured out of them as kids. And it works on Cara ''again'' [[spoiler:when she's tortured back to the dark side by Darken Rahl]].
* ''Series/SevenDays''; one episode centered around a Presidential candidate whom time-traveler Frank Parker [[SetRightWhatOnceWasWrong rescued from an assassination attempt]]. The candidate offered Frank a position in his campaign team. Later, Frank learned that the candidate had been tortured by Chinese soldiers during the Vietnam War. As President, he planned to destroy a US Navy vessel, implicate China and declare war, with the ultimate goal of killing the population of China.
* ''[[Series/SpartacusBloodAndSand Spartacus War Of The Damned]]'': Features a fairly realistic version. Naevia spent some time as a SexSlave to various Romans, and spends much of ''Vengeance'' as a BrokenBird. In ''War of the Damned'' she comes off as an AxeCrazy DarkActionGirl wanting to slaughter all Romans, even perfectly innocent civilians and children.
* ''Series/DoctorWho'':
** Being tortured and mutilated by South American natives for trespassing on their territory is what drove George Cranleigh mad and turned him into a murderer in "Black Orchid".
** In "Heaven Sent", the Doctor is imprisoned in a castle that is really, in his words, a "bespoke torture chamber" in the ''immediate'' wake of [[spoiler: Clara Oswald's Senseless Sacrifice]] in the previous episode, which means his anguish and anger are extremely fresh. Completely alone save for a monster with a TouchOfDeath he can only evade or temporarily halt, he is tormented physically and psychologically all in an effort by his captors to extract information about the Hybrid warrior of a Gallifreyan prophecy from him. Determined not to reveal everything he knows, he winds up [[spoiler: finding another way out by dying and recreating himself billions of times over billions of years]]. He emerges from this as TheUnfettered and a WoobieDestroyerOfWorlds ready to [[BatmanGrabsAGun grab a gun and use it]] in "Hell Bent", determined to [[spoiler: bring Clara back from death]] by any means, even if the universe is destroyed in the process. While his anguish would make him dangerous in any case, if not for what he undergoes in "Heaven Sent", he probably would not resort to such extreme measures and violations of his principles. The good news is that he stops short of crossing the MoralEventHorizon and chooses to return to his best self by way of setting up the BittersweetEnding.

* Tripod's "Suicide Bomber" is somewhere between this and ThenLetMeBeEvil. The singer is repeatedly tortured in an unsuccessful attempt to make him confess to a bombing he didn't commit. By the end, he's patiently awaiting his release so he can suicide-bomb a bus, knowing full well that another innocent person will probably be tortured and made to confess to the crime. (This is completely PlayedForLaughs.)

[[folder:Tabletop Games]]
* In ''TabletopGame/DungeonsAndDragons'', torture in Hell makes bad people worse - after some time they hate their tormentors so deeply that the last remains of their humanity snap and they start to transform into bottom-rank devils themselves.
** [[http://www.dlogs.net/monsters/new_65.htm Here]] D&D continues the process to it's logical conclusion: '....After almost three years of hideous, painful torture, the creature that crawled into the pit a gelugon crawls out of it a pit fiend....'
** In ''TabletopGame/ForgottenRealms'' one of the Red Wizards' nastiest weapons are the "Chosen Ones" -- normal people (usually stubborn slaves) who were forced to undergo excruciating transformation, and when ordered to fight they are deluded to see the foe as [[BerserkButton the one who transformed them]]. They aren't used ''en masse'' because they frequently slip out of control, stop mid-strike and run away, to find the ''real'' wizard whom they want to shred.
** The Iron Ring, a slave-trading secret society from the ''TabletopGame/{{Mystara}}'' setting, acquires its Mooks via this trope, torturing people they've taken captive until they're reduced to mindless berserkers. Such "Hounds" are virtually incapable of coherent thought, retaining just enough wits to cringe before their captors' whips, that herd them into battle.
* In ''TabletopGame/ChangelingTheLost'', [[TheFairFolk The True Fae]] are sociopathic monsters incapable of compassion. They reproduce by abducting humans from the real world, (usually) subject them to constant, brutal, horrific tortures, and then once the last bit of their humanity is stripped away, they become True Fae.
* ''TabletopGame/KindredOfTheEast'': Your average ''Kuei-jin'' 1) were tossed to hell, where they [[AndIMustScream suffered from constant torment]], then 2) [[CameBackWrong crawl back to the world of the living]] to do some unfinished business, and 3) have their [[DamagedSoul lower soul constantly agitated due]] to their time being tormented in hell. Is it a wonder that most of them turn into cannibal ghouls, and are just one step away from turning into OneWingedAngel even in their most collected moments?

[[folder:Video Games]]
* This is pretty much word-for-word the backstory for [[ColdSniper Widowmaker]] in ''VideoGame/{{Overwatch}}''. She was kidnapped by Talon agents and tortured/brainwashed until they literally "broke her will, suppressed her personality, and reprogrammed her as a sleeper agent."
* In the first ''VideoGame/DungeonKeeper'' game, you can torture captured heroes into joining your side. As long as you're careful not to kill them (which turns them into fairly mediocre Ghosts), anyone will break eventually...
** This even includes the [[BigGood Avatar]], although it takes a very long time. However, since the Avatar is supposed to [[BackFromTheDead come back]] when you kill him, if you don't and convert him then his also good twin shows up to fight you.
** Enemy Mistresses, however, doesn't join your forces because your torture has broken their spirits. [[TooKinkyToTorture They happily and willing join you out of gratitude for being tortured]].
** It works the same way in the sequel, though torturing your enemies to death now causes them to reveal map information to you instead of turning into Ghosts.
* In ''VideoGame/BatmanArkhamKnight'', while not "evil" per say, [[spoiler: Jason Todd is tortured for a year by the Joker and this eventually turns him to the Arkham Knight. Subverted slightly as he doesn't become a complete villain and still cares about the rest of the Bat Family, but certainly a different take than how he became Red Hood in the comics.]]
* In ''VideoGame/KnightsOfTheOldRepublic'', Malak turns Bastila to TheDarkSide... by hitting her repeatedly with Force Lightning. Makes you wonder if TheEmperor was trying to duplicate that stunt at the end of ''Film/ReturnOfTheJedi''.
-->'''Malak''': "No, you misunderstand. This is but a taste of the Dark Side, to whet your appetite."
** Torture is a standard method for Sith "converting" light-side Jedi, as mentioned in ''[[VideoGame/KnightsOfTheOldRepublicII KotOR II]]'' and shown in other parts of the ''Franchise/StarWarsExpandedUniverse''. It's a good way to crack a Jedi's emotional control, [[TeachHimAnger getting them angry]] and setting them at the top of the slippery slope.
** Because the Sith have practically built their religion around the idea of the apprentice betrays the master thing, the loyalty issue is less relevant for them. Being TheStarscream is downright ''desirable'' among the Sith.
** And the DarkSide of the Force acts as psychological {{phlebotinum}} that explains any remaining bits about Jedi turning evil that don't make sense as such.
* [[spoiler:Aribeth]] in ''VideoGame/NeverwinterNights'' turned to the dark side following some pretty severe psychological torture (read MindRape).
** The character in question was on the path before that, seeing as how [[spoiler:her love interest,]] a genuinely good, innocent person, was executed by the bloodthirsty populace demanding justice. It's not hard to imagine [[spoiler:her falling, seeing as how her patron deity's portfolio is, specifically, justice.]] Taken back in the second add-on, ''Hordes of the Underdark'', where [[spoiler:Aribeth states that her affection for Fenthick was more due to her devotion to her faith than because of her love for him - or, as she states it: "it was like being married to my church" (she was a paladin of Tyr, he was a priest). So her decision to defect was not because she went insane from grief but rather out of her own wantonness.]]
* Jak from ''Franchise/JakAndDaxter'' goes halfway there by going from WideEyedIdealist to cynic AntiHero with a SuperpoweredEvilSide. While he was not tortured for the sake of torture, he ''was'' subject to two years of Dark Eco experimentation, pumping him full of the stuff, in the Baron's attempts to create a SuperSoldier. Dark Eco tends to have some ''really'' nasty effects on people exposed to it, ranging from insanity to outright killing a person.
* In ''{{VideoGame/Diablo}}'' lore, the angel Izual was captured by the forces of evil and tortured until he became evil. After you kill him he reveals [[spoiler:that he was EvilAllAlong, and was the one who kicked off the 'Soul Stone' thing with the direct intention of helping The Three]].
** In ''VideoGame/DiabloIII'' this is inverted with the Templar recruiting process. Criminals are tortured for days to purge them of their memories and sinful impulses, turning them into noble champions. Kormac eventually unlocks his buried memories and learns [[spoiler:he was a good man before joining the Templars; the torture merely made him unquestioningly loyal to their orders]].
* ''VideoGame/MetalGearSolid4GunsOfThePatriots'' has [[QuirkyMinibossSquad The B&B Corps]], civilian women who've been driven insane by the horrors of warfare, and undergone transformation into super soldiers in the misguided belief that fighting will ease their trauma. Each one plays the trope in a slightly different way:
** Laughing Octopus both plays it straight and inverts it; she was kidnapped by a cult and forced to torture her family and friends to death, and said cult also forced her to react as though she took sadistic amusement in their suffering when committing the action.
** Raging Raven plays it completely straight; she was locked in a cage and tortured for the amusement of a band of soldiers until she came to hate the world, and when she was finally freed by the sheer luck of the ravens' pecking killing the ropes faster than her life, she went on an UnstoppableRage.
** Crying Wolf was left traumatized when her family (except her and her baby brother) were slaughtered in an ethnic cleansing. [[FromBadToWorse To make matters worse]], while hiding from some soldiers who were hunting her, she accidentally smothered her brother rather than let his crying draw the soldiers to her location. And THEN she found a refugee camp, which promptly disposed of the rotting corpse of her brother that she lugged around. One AxeCrazy fit later, and she had murdered them all in their sleep.
** Screaming Mantis is a slight variation; she was locked in a basement beneath a torture chamber, and driven insane by the sound of screams echoing above her. The kicker? The chamber ''housed the dead corpses of torture victims''. ''She had to eat them to survive''.
* VideoGame/MetalGearSolidVThePhantomPain'': Kaz is no longer the peppy TeamDad after nine years, two amputated limbs, and cataracts.
* Saavedro from ''VideoGame/MystIIIExile'' was tied to a post, severely beaten, and was left on several small islands for 20 years, while believing that his family, nay, his entire world was dead. His mind is...not where it used to be, as evidenced by passages in his journal detailing how much he had forgotten and how desperate he was for revenge.
* ''VideoGame/CaveStory'' Apparently, the difficult-path ending boss used to be a real nice guy... until someone got jealous of him and decided to torture him for a while. Now... well... He's... not so nice anymore. Though he averts the "joins his captors" aspect of the trope.
** Though it's not so much that he lost his morals as that he lost his self-control. He even [[ICannotSelfTerminate wants you to kill him.]]
* Averted in ''VideoGame/WorldOfWarcraft''. The Lich King tries to torture Bolvar Fordragon after capturing; [[spoiler:It doesn't work, and Bolvar actually ends up replacing him.]]
** After a long questchain in Coldarra [[spoiler:Keristrasza is taken captive by Malygos and forced to become his consort as a replacement for Saragosa who Keristrasza and the player character had killed. The players then MercyKill her after she's proven herself too insane to be saved from death and too much of a threat to be allowed to live, because going on a mass murdering rampage was a likely outcome.]]
** Partly played straight with [[spoiler:Maiev Shadowsong]] after [[spoiler:her]] capture and torture at the hands of [[spoiler:Illidan Stormrage]]. While [[spoiler:she]] does go crazy and start metting out [[spoiler:her]] own brand of justice, the torture is only the last straw that takes [[spoiler:her]] over the edge of sanity. Although she gets somewhat better later on.
** It turns out that after Sargeras killed the [[spoiler:rest of the Titans]], he captured their souls and has spent millennia torturing them in an attempt to create his own [[spoiler:Dark Pantheon]]. He succeeded with [[spoiler:Aggramar]] and the rest have nearly given in.
*** [[spoiler:Argus]] was tortured for eons and was finally driven insane at the moment his soul was taken to the [[spoiler:Seat of the Pantheon]].
* Corvus from ''VideoGame/DragonQuestIX'' was a nice guy... before being captured by TheEmpire and spending 300 years in prison, every limb chained and his energy being drained to maintain TheEmpire's magic. He was a little angry at the world in general after that.
** It wasn't just being imprisoned by the Gittish Empire; it was also the fact that he had been sold out by the very town that had taken him in, including his lover. Apparently, she wasn't in on the plan to have Corvus arrested, believing she was subduing him with a sleeping potion because she and him were to hide at a nearby lake, and his ChronicHeroSyndrome would have caused him to ditch the hiding spot. He didn't realize this, and thought she was also betraying him. The betrayal and torture filled Corvus with so much hatred and grief that he eventually came to hate the mortal realm and all its inhabitants; all of Corvus' negative emotions became so strong that he [[OneWingedAngel turned into some sort of demon]] with the strength to [[spoiler:rend the very heavens asunder with enormous dark energy beams]] and [[NintendoHard use the sickeningly powerful Magic Burst spell in battle]]. It was the betrayal that drove him to evil, and the torture that made him [[BigBad powerful]].
* Broodmothers from ''VideoGame/DragonAgeOrigins'' were once regular females before going through a sickening creation process that involves them screaming out of control for a day straight, having Darkspawn vomit into the mouths of said females, and Darkspawn gang raping them. Then they get force-fed the flesh of their own species. Near the end of the process, the women ''willingly'' and ''eagerly'' tear apart their former loved ones and devour them with relish. Not long after that they become full fledged Broodmothers.
** Although he's not exactly "evil", this is a lot of how Fenris got the way he is. After being put through a ritual that burned Lyrium into his skin, one that was so mentally scarring he's forgotten his entire life up to that point, and his Tevinter Magister master being indescribably petty and cruel, he's turned into a brooding, skulking mess of a man. [[MrFanservice That doesn't stop the ladies from squealing]] over him... [[EvenTheGuysWantHim Or the menfolk]].
** Anders gets this as well. Even in ''Awakening'', before he was possessed by a corrupted Spirit of Justice and started hanging out next to a literal hellmouth in Kirkwall, one gets the impression that the seven escape attempts from the Circle of Magi weren't just because the guy wanted some fresh air.
* The ([[NoExportForYou Japanese]]) novel for ''[[VideoGame/KingdomHeartsBirthBySleep Kingdom Hearts Birth By Sleep]]'' seems to imply this is what happened with Vanitas.
* In ''VideoGame/{{Skullgirls}}'', Lab Zero did their best to do this with Painwheel. [[spoiler:In both her and Filia's ending, it doesn't stick. She breaks free in the former, and is saved by Filia's wish for her to have a normal life in the latter.]]
** This is also explained as the origin story for Peacock... sort of. She went totally psycho after enduring gruesome, horrible torture, but never joins up with her tormentors. She has a decidedly heroic role, though she [[HeroicComedicSociopath favors violent methods]].
* ''VideoGame/BioShockInfinite'': Near the end of the game, [[spoiler: Booker is sent to a BadFuture where years of torture and psychological conditioning have rendered Elizabeth so afraid of Comstock that she cannot bring herself to defy him even decades after his death. Instead, she becomes his successor and carries out his plan to purify "the Sodom below" by destroying New York City. However, she does feel guilty enough to give Booker a message for her past self that she hopes will SetRightWhatOnceWentWrong]].
* ''Franchise/MassEffect'': Being kidnapped, tortured, and experimented on from infancy by Cerberus turned Jack into the most powerful human biotic ever. It also turned her into [[AxCrazy a homicidal ball of rage]], who one wrong move could set off at any moment. Under Shepard's influence, she can greatly improve and become a genuinely heroic person, though she still holds onto her BloodKnight tendencies, [[RoaringRampageOfRevenge especially when Cerberus is around]].
--> '''Jack:''' They thought they were so clever. Turns out, mess with someone's head enough and you can turn a scared little kid into an all-powerful bitch. Fucking idiots!
* ''CallOfDutyGhosts'' has Rorke, a former Ghost who was captured and tortured by the Federation, turning him into their best assassin and soldier whose primary focus is hunting down his former comrades, especially his former commanding officer, who Rorke believes betrayed him.
* ''VisualNovel/FateStayNight'': Angra Mainyu became a being filled with absolute hatred for humankind after a lifetime of being tortured by his own village, all because they had chosen him at random to be [[TheScapegoat "The Source of All Evil"]]. [[spoiler:Should the Holy Grail War be seen through to the end, his corrupting influence on the Grail will lead to him being unleashed upon Earth, an act that could very well lead to mankind's extinction. In ''VisualNovel/FateHollowAtaraxia'', however, the influence of both the Holy Grail and Shirou lead to him finding some peace, despite everything.]]

[[folder:Web Comics]]
* A variant in ''Webcomic/{{Goblins}}'' existed with the Fat Guard's plan. He believed that sufficient torture could turn powerful, but largely non-aggressive, monsters into killing machines that could be used to defend Brassmoon. When he released it, he found to his dismay that [[HoistByHisOwnPetard only the first part had worked]].
* The seven demonic Dire Unicorns in [[http://www.daemonslayers.net/links.htm The Daemonslayers]], including Blackjack's somewhat loyal mount and [[MixandMatchCritters unicorn/dragon]] hybrid Knightmare, were all once pure and noble unicorns. When they were captured by the Demon Queen, Shine, and her minions, they were horribly tortured and corrupted with her dark magic into twisted beings who could no longer remember their names and former lives. The only unicorn who still retained much of his former self was Frenzy. Unfortunately, since the universe he inhabits is [[CrapsackWorld such an awful place to live in]] that it happily wishes to screw, torture and maim any decent being that lives in it, he is cursed with a blood red mist that is like a {{Hate Plague}} to anyone who breathes it. Because he remembers his former life, Frenzy is the most peaceful of the dire unicorns, yet seeing the effects time and again of the horrible curse of rage and destruction that travels with him caused him to slowly lose his mind and is now quite insane.

[[folder:Web Original]]
* In ''Roleplay/TheGamersAlliance'', Omaroch, Kaizoku, Tanya and Izael end up captured by their enemies who turn them on their side with a combination of torture and mindrape.
* Done successfully to IncorruptiblePurePureness in ''WebAnimation/BrokenSaints''. Justified in that said character is an [[TheEmpath empath]], and the torture was simply necessary to turn [[spoiler:her]] into a conduit for negative emotion. Not that that makes [[EyeScream any of the torture]] less disturbing.
* While Nights of ''Roleplay/{{AJCO}}'' was hardly a saint to begin with, following the psychological torture she suffered during the Silo arc she lost her only redeeming feature - her love for the Castle Crew.
** And ''then'' when she tried to reclaim power by threatening Breyos, he injected her with deadly spider venom and left her to die. She's now [[DespairEventHorizon completely broken and loyal to AJCO]]. At least for now.
* In ''Literature/{{Addergoole}}'' a lot of the worst Keepers are those who were abused when they were Kept previously.
* In ''WebVideo/TheSpoonyExperiment'', Spoony recounts the time his ''TabletopGame/VampireTheRequiem'' LARP character was captured and tortured into joining the [[KnightTemplar Lancea]] [[ReligionOfEvil Sanctum]] and does the horrible things they tell him to. [[{{Subversion}} For the first session.]] Pissed off they tried to forcibly take over his character, Spoony decided to fight back, used his massive chemistry score to make a bathtub full of Semtex, sneaked it into the Vampire Prince's sanctum without anyone noticing, then went to his car and used the detonator. If not for GM fiat, Spoony would have leveled the building and took with it the head of the oppressive vampire hierarchy. (Just for reference, this is a LARP, there was no actual Semtex or detonators, just index cards that say that).

[[folder:Western Animation]]
* [[spoiler:Robin]] in ''WesternAnimation/BatmanBeyondReturnOfTheJoker'' was turned into [[spoiler:a miniature, nearly catatonic replica of the Joker]] after weeks of being drugged and tortured by the Joker. It [[spoiler:didn't really stick since, when faced with an order to kill Batman, he instead killed the Joker]], but it took years to recover and eventually led to [[spoiler:his brain being hijacked by a secretly implanted microchip imprinted with the Joker's personality]].
* A similar situation occurs in ''WesternAnimation/TheBatman'' when [[spoiler:Ethan Bennet]] is tortured and driven insane by the Joker, and the chemicals used on him [[spoiler:turn him into Clayface]]. Determined to kill the Joker, he didn't care who got in the way. [[spoiler:Fortunately, he redeemed himself]].
* [[Anime/TransformersEnergon One incarnation of Megatron]] attempted this on the Autobot Inferno. Megatron tortured Inferno for information and his own amusement. When Inferno still wouldn't break, Megatron tried forcibly converting him to the Decepticon cause. Although Inferno was eventually rescued by the other Autobots it looked like he might turn on them. In the end [[spoiler: Inferno [[SubvertedTrope fought off the effects of Megatron's influence]] and died.]]
** [[WesternAnimation/TransformersPrime Another incarnation of Megatron]] found himself on the receiving end of this trope courtesy of [[GodIsEvil Unicorn]] [[spoiler:after his [[BackFromTheDead corpse was revived]] [[DemonicPossession and used as a puppet by Unicorn]] while his spirit]] was being brutally tormented. However, [[spoiler:this trope is {{inverted}} because Megatron had died in the final battle for Earth with the Autobots and originally hoped that Unicorn would help him take revenge on them; in fact, his torture actually spurred a HeelRealization and he disbanded the Decepticons after he was freed.]]
* Shockingly enough for a {{Creator/Disney}} [[WhatDoYouMeanItsForKids cartoon series ostensibly aimed at kids]], ''WesternAnimation/TronUprising'' goes here in "Scars." While Tron's torture at the hands of Dyson didn't ''completely'' turn him to the dark side, it's coming pretty close [[spoiler: And probably helps Clu [[ReforgedIntoAMinion twist him into "Rinzler" later]] ]] - to the point where he tries to ''kill'' Beck for intervening in his RoaringRampageOfRevenge.
* Hama, an old lady the protagonists encounter late in ''WesternAnimation/AvatarTheLastAirbender'', was a waterbender in the Southern Water Tribe who through years of attrition, desperation, a cruel prison, lack of access to her element, and discovering a [[PeoplePuppets technique]] that warped her, went from apparently normal and friendly to someone who ''appeared'' friendly but happily abducted and imprisoned random civilians of her torturers' Nation and quickly turned against the nice Water Tribe kids who objected to her.
