History LoveMakesYouEvil / AnimeAndManga

* Lelouch vi Britannia in ''Anime/CodeGeass''. Lelouch seems to be rather affectionate towards his sisters. Lelouch often dotes on her and promises that he'll create a better world for her which essentially means manipulating, blackmailing, sacrificing, and disposing whomever he wishes to ensure that his rebellion in Japan achieves a violent revolution against the Holy Britannian Empire.

* In ''Manhua/GoddessCreationSystem'', after [[spoiler:Ping Yang Hou's]] wife was indirectly assassinated he quietly went crazy after he figured it out and began plotting to [[spoiler:seize the throne and destroy the royal family.]] He might even have made for [[spoiler:a good king]] nonetheless despite [[spoiler:usurping the throne]] but his obsession with his dead wife causes him to force through [[spoiler:impossible imperial edicts, even executing a man on the spot for refusing to have his dead wife acknowledged as queen.]]

* ''LightNovel/DateALive'':

%%* Shinra of ''LightNovel/{{Durarara}}'', despite being an otherwise NiceGuy, has explicitly identified himself as stated in the quote at the top of this page.

* ''LightNovel/HighSchoolDXD'':

* ''Anime/PuellaMagiMadokaMagicaTheMovieRebellion'' [[spoiler:takes this trope to its LogicalExtreme. Homura's Soul Gem is corrupted by [[ThePowerOfLove her love for Madoka]], and she steals Madoka's powers. This turns Homura into ''[[SatanicArchetype the devil]]'']].
** Just to be clear [[spoiler: Homura doesn't want Madoka all to herself; in fact she doesn't even care if Madoka loves her back. Rather, Homura [[IWantMyBelovedToBeHappy just wants to see Madoka happy]]...and because she loves Madoka so much, [[WellIntentionedExtremist she's willing to go to any lengths to do so.]] In fact, it's the strange interaction of BOTH character's selfless attitudes that cause this to happen. The catalyst is Homura meeting a Madoka with amnesia (effectively a Madoka in the past) who expressed desire to be normal and live her own happy life, which directly contrasts the current Madoka's extremely selfless "protect the happiness of everyone at the cost of myself" attitude. This means that in order to protect and satisfy THAT Madoka, she has to directly betray the current, selfless Madoka. So she's acting in the selfish interests of a person who's become deeply selfless, the evil part comes in the ambiguity of just how much damage she chose to cause in the process]].

%%** This trope spawns Judai's StalkerWithACrush (Yubel) and all the problems in Season 3 of ''Anime/YuGiOhGX''.
** [[spoiler: Carly]] in ''[[Anime/YuGiOh5Ds 5D's]]''. So evil that she claims [[spoiler: that she became a Dark Signer just so she could kill Jack and they could be together]]. Thought technically, not so much evil as [[spoiler: suffering from a bad case of BrainwashedAndCrazy, coupled with a SuperpoweredEvilSide]].

** This trope spawns Jaden's StalkerWithACrush (Yubel) and all the problems in Season 3 of ''Anime/YuGiOhGX''.

** This trope spawns Judai's StalkerWithACrush (Yubel) and all the problems in Season 3 of ''Anime/YuGiOhGX''.

* A recurring theme in the current arc of ''Manga/{{Naruto}}'', is that love (not exclusively romantic love) can lead to hatred and war. This is seen in [[spoiler:Sasuke wanting to destroy Konoha in order to avenge Itachi]] and [[spoiler:Pain]]'s StartOfDarkness.

* Chikane Himemiya from ''Manga/DestinyOfTheShrineMaiden'' does this to the point of [[spoiler: violating her friend]]. This is all so that her friend will be willing to [[spoiler: kill her.]] This is because she is guilty over killing that same friend [[spoiler: in a past life where they were lovers]].

* This is [[spoiler: Ren Sohma]]'s FreudianExcuse in ''Manga/FruitsBasket''. [[spoiler: She was the maid who took care of the former leader of the Sohmas, [[IllGirl Ill Boy]] Akira, and the only one able to reach for him. But when Ren married him, got pregnant and started fearing that he'd love her less once their child was born... Ooooh, boy.]]

** Sibling love ([[spoiler:a Buddhist novice kills his master after learning he murdered his older brother, an average guy becomes a thief to force the police investigate his younger sister's presumed murder, a ghost writer brutally kills his boss after he causes the death of his IllGirl sister when he was supposed to pay for her treatment, an InnocentFlowerGirl brews a ThanatosGambit to punish her older sister's rival who stole her tricks and drove her to kill herself; an uni student enters a local {{Tokusatsu}} fan club and kills the biggest {{Otaku}} in the group for stealing his little brother's memorabilia out in the open and cauing the kid to get hit by a truck]];

* ''Anime/PuellaMagiMadokaMagicaTheMovieRebellion'' [[spoiler:takes this trope to it's LogicalExtreme. Homura's Soul Gem is corrupted by [[ThePowerOfLove her love for Madoka]], and she steals Madoka's powers. This turns Homura into ''[[SatanicArchetype the devil]]'']].

* ''Franchise/SailorMoon'': Queen Beryl is the straightest example in the series, at least in the [[Manga/SailorMoon manga]] and ''[[Anime/SailorMoonCrystal Crystal]]''. She was an ordinary human girl whose unrequited love for Endymion made her a prime target to be corrupted by Metaria. This resulted in her becoming evil, spreading Metaria's influence across the planet, and leading an attack on the Moon Kingdom which led to its fall and the deaths of everyone in the Solar System, most of them indirectly. [[UpToEleven So Beryl's the reason everyone was reincarnated in the modern day]]. Also overlaps with TheDarkSideWillMakeYouForget as ''she'' was the one who killed Endymion (either that or IfICantHaveYou). Possibly inverted in the [[Anime/SailorMoon 90s anime]], though it's hard to tell considering Beryl has no backstory. She still loves Endymion, but it seems she was always evil.

** A son/daughter's love for their families ([[spoiler:the [[AntiVillain anti villainous]] [[HarmlessLadyDisguise Crossdresser]] who kills almost everyone related to his parents and siblings's deaths when he was a little IllBoy, the SexySecretary who makes a CorruptCorporateExecutive believe that she kidnapped and killed his daughter as revenge for him causing the ruin and death of her family, the Osakan cop who becomes a SerialKiller to punish the people who caused his father's death in a prank GoneHorriblyWrong]]);

* ''Manga/TsubasaReservoirChronicle'': BigBad Fei-Wang Reed is all but outright stated to be this. He claims the purpose of his plans is to prove he's the most powerful magician of all time, but some of his words later seem to suggest otherwise. He enacts a centuries long unimaginably complex GambitRoulette that involves the death of millions (if not billions — at least one UNIVERSE has ended by [[FanNickname Ass-chin's]] deeds), all for the sake of bringing someone ([[spoiler: [[Manga/XxxHOLiC Yuuko]]]]) back to life. Or keeping her from dying. Un-dying? Un-unkilling her? Terminology gets ''really'' confused at this point, [[MindScrew as does the reader]]. She died years ago, but a [[Manga/CardcaptorSakura certain]] RealityWarper with PowerIncontinence accidentally caused the universe to not notice it; Fei-Wang wants to either keep this state of affairs or make her 100% alive rather than zombie-ish. [[spoiler:Eventually, it's revealed that Fei-Wang Reed was likely to be the "afterimage of a wish made by someone with strong magic", meaning that he was probably created out of the said {{Reality Warper}}'s deep subconscious desire for Yuuko to stay alive, i.e. he was the ''physical manifestation'' of "Love Makes You Evil".]]

** The vast majority of villains in this franchise invert it, already being evil. Classic examples include Zoisite from Season 1 and Koan from Season 2 of the anime. The former had no redeeming qualities, but was at his most vicious when trying to please or [[AttentionWhore get attention from]] his older boyfriend and mentor Kunzite. The latter was already a vain, catty, shallow bitch obsessed with make-up, but was willing to go to extremes to get Rubeus to fall in love with her, ''including blowing herself up''.

* [[SchoolgirlLesbians Chikane Himemiya]] from ''Manga/DestinyOfTheShrineMaiden'' does this to the point of [[spoiler: violating her friend]]. This is all so that her friend will be willing to [[spoiler: kill her.]] This is because she is guilty over killing that same friend [[spoiler: in a past life where they were lovers]].
