History LoveMakesYouEvil / VideoGames

* In the UsefulNotes/PlayStation game ''VideoGame/ValkyrieProfile'', Lezard Valeth kidnaps his old teacher's husband, [[TheVirus turns him into a hideous monster]], gets the monster to kill said teacher, [[PoweredByAForsakenChild murders multiple elves to make a homunculus]] that appears to be around ten years old, and tricks one of his old classmates into killing themselves by becoming a HumanPopsicle, so that he can force the main character to incarnate into flesh and marry him. When that doesn't work, should you earn the [[MultipleEndings best ending]], [[spoiler: he deliberately kills himself to turn into a spirit being like those the main character leads about, allies himself with a vampire, kills the main character's older sister, and ensures Odin has no chance of surviving TheEndOfTheWorldAsWeKnowIt]]. To top it all off, he [[KarmaHoudini gets away with it all]], even though he doesn't succeed... this time.

* In ''Franchise/BlazBlue'', [[spoiler:[[ClingyJealousGirl Tsubaki]] [[LightIsNotGood Yayoi]] is tricked by [[{{Troll}} Hazama]] (who's actually [[BigBad Yuuki Terumi]]) to believe that her old school friend [[{{Moe}} Noel]] [[TheGunsliner Vermillion]] stole away her chance to be with her love interest [[TallDarkAndSnarky Jin]] [[{{Jerkass}} Kisa]][[AnIcePerson ragi]]. She ends up performing a FaceHeelTurn and attempting to [[MurderTheHypotenuse kill Noel]]. Thankfully, she gets better]].

* In ''VideoGame/BlazBlue'', [[spoiler:[[ClingyJealousGirl Tsubaki]] [[LightIsNotGood Yayoi]] is tricked by [[{{Troll}} Hazama]] (whose actually [[BigBad Yuuki Terumi]]) to believe that her old school friend [[{{Moe}} Noel]] [[TheGunsliner Vermillion]] stole away her chance to be with her {{Love Interest|s}} [[TallDarkAndSnarky Jin]] [[{{Jerkass}} Kisa]][[AnIcePerson ragi]]. She ends up performing a FaceHeelTurn and attempting to [[MurderTheHypotenuse kill Noel]]. Thankfully, she gets better.]]

* In ''VideoGame/XenobladeChronicles3'', this is what drove [[spoiler:a prior incarnation of Noah]] to join up with Moebius. Having watching his loved one die right before his eyes [[spoiler:[[ReincarnationRomance through multiple short lifetimes]]]], he was convinced by [[BigBad Z]] that it was pointless to continue to resist. As such, he chose to become Consul [[spoiler:N]], and carried out Z's order to [[spoiler:lay waste to the City that he and Mio had helped to found (and was likely populated at least in part by any descendants of the child sired by an earlier incarnation of Noah and Mio may have had), in order to obtain the life force needed to resurrect her and induct her in as Consul M]], all for the prospect of living forever with her.

* Love is one of the central themes in ''Mask of the Betrayer'', the expansion/sequel to ''VideoGame/NeverwinterNights2''. Putting aside more exotic variants like the love between man and god, [[spoiler: the entire plot and background of the game, including the horrible fate that befalls the protagonist right at the beginning, occurred because Akashi and the Founder were in love. Myrkul]] finds it amusing.
-->"Only ''love'' could be so cruel, I think."

** ''VideoGame/FireEmblemTheBlazingBlade''[='s=] [[spoiler:Nergal originally wanted to find his missing wife, but when that didn't work out, he sought to open the Dragon's Gate and reunite with his lost children (Ninian and Nils), hence his obsession with harnessing the power of the dragons and delving into dark magic. It eventually [[TheDarkSideWillMakeYouForget warped his soul]] and transformed him into the power-mad BigBad of the game]]. Averted with Dorcas; he joins a gang of bandits to earn money for medicine for his IllGirl wife, but you can have Lyn talk some sense into him, tell him that the wife is her protegé now and convince him to join her side.
** ''VideoGame/FireEmblemTheSacredStones'' has [[spoiler:Orson (he betrayed his country to have a chance to revive his wife Monica, ex IllGirl who died prior to the game's events.]], [[spoiler:General Carlyle (Queen Ismaire's long-time StalkerWithACrush)]] and [[spoiler:Prince Lyon (he adored ''both'' Eirika and Ephraim and was at the same time jealous of them since he was an [[IllGirl Ill Boy]], which contributed to him being susceptible to falling under Fomortiis' thrall)]].

* Taken [[UpToEleven up to]] the [[SerialEscalation EXTREME]] with [[spoiler:Adele]] from ''VideoGame/ArcRiseFantasia'', when she becomes a {{Yandere}} [[TheVamp vampy]] high priestess of a ReligionOfEvil upon learning that she was the hero's [[ChildhoodFriendRomance Unlucky Childhood Friend]].

* ''VideoGame/FireEmblem'' is pretty fond of this one:
** ''Mystery of the Emblem'''s Hardin [[spoiler:fell into despair after finding out that his longtime BodyguardCrush and newly-married wife Nyna didn't truly love him back, leaving him open to be corrupted by the [[ArtifactOfDoom Darksphere]]]].
** ''Genealogy of the Holy War'''s Arvis loved Deirdre so much he [[spoiler:[[HypnotizeTheCaptive
brainwashed her into loving him]] and killed her husband Sigurd out of fear that she might remember him]].
** ''Blazing Blade'''s Nergal [[spoiler:originally wanted to bring back his dead wife, hence his obsession with harnessing the power of the dragons and delving into dark magic. It eventually [[TheDarkSideWillMakeYouForget stole his soul]] and transformed him into the power-mad BigBad of the game]]. Averted with Dorcas; he joins a gang of bandits to earn money for medicine for his IllGirl wife, but you can have Lyn talk some sense into him, tell him that the wife is her protegé now and convince him to join her side.
** ''VideoGame/FireEmblemTheSacredStones'' has [[spoiler:Orson (he betrayed his country to have a chance to revive his wife Monica, ex IllGirl who died prior to the game events.]], [[spoiler:General Carlyle (Queen Ismaire's long-time StalkerWithACrush)]] and [[spoiler:Prince Lyon (he adored ''both'' Eirika and Ephraim and was at the same time jealous of them since he was an [[IllGirl Ill Boy]], which contributed to his madness later)]].

** ''[[VideoGame/FireEmblemRadiantDawn Radiant Dawn]]'' has [[spoiler:Almedha, who is willing to sacrifice an entire country to save her son Pelleas after his DealWithTheDevil]].

** ''Genealogy of the Holy War'''s Arvis loved Deirdre so much he [[spoiler:[[HypnotizeThePrincess brainwashed her into loving him]] and killed her husband Sigurd out of fear that she might remember him]].

** Add to this the number of protagonists [[UnwittingPawn who inadvertently contribute to Dracula's return]] due to the [[StuffedIntoTheFridge death]] or [[DamselInDistress capture]] of their [[DisposableWoman romantic interests]], and one gets the distinct impression that the entire series could have been avoided if everyone could just get over these things.
