** [[TheHeart Clementine]] can be this for [[AntiHero Lee]], depending on how the player chooses to portray him.

* In ''VideoGame/TheWalkingDead'', [[TheHeart Clementine]] can be this for [[AntiHero Lee]], depending on how the player chooses to portray him.

* In ''VideoGame/CastlevaniaChroniclesOfSorrow'', [[spoiler:Soma Cruz will [[MultipleEndings immediately turn evil]] should something happen to Mina Hakuba, his love interest.]]

* In ''VideoGame/PlanescapeTorment'' you meet a devil called Fhjull Forked-Tongue. He made an angel called Trias enter into a DealWithTheDevil with him, hoping to corrupt Trias to evil. Unfortunately, Trias was better at contract manipulation, and Fjull got stuck with the short straw: By the contract, he bound to be good for as long as Trias is alive; breaking the contract would mean his death. Trias, on his end, does not have to fulfill any part of the contract for as long as Fjull is still in the process of fulfilling his own stipulations (in other words, Trias gets off scot-free until Fhjull willingly becomes LawfulGood, [[MortonsFork at which point Fhjull wouldn't want Trias to fulfill his part of the bargain]]). Although forced to be good, Fjull is still allowed to be bitter about it, which he is. ''Oh so very much''.

*** If Tharja gets married her husband becomes this to her. While he cannot ''completely'' keep her darker sides at bay, he at least manages to keep her mildly functioning. [[spoiler: When he dies in the Bad Future, Tharja ''[[DespairEventHorizon completely snaps]]'' and becomes a very dark mixture of AbusiveParent and CrusadingWidow who only ''sorta'' recovered some bits of her sanity when it was time to pull an HeroicSacrifice for Noire.]]

** Come Season Four, after AJ [[spoiler: shoots Marlon when he wasn't a threat anymore,]] it's your job to figure out whether or not you want to brush it off and tell him that he did the right thing, or make it clear to him that he's now [[spoiler: a murderer]] and he needs to make it up to everyone. Your choice sends ripples through his attitude going forward, and the more he learns about killing and human cruelty, the more you have to decide how callous you want to let him become.
* In ''VideoGame/WorldOfWarcraft: Cataclysm'', the night elf Leyara is a key member of Fandral Staghelm's Druids of the Flame, who answer to the malevolent Old God-aligned Ragnaros the Firelord. [[spoiler: She goes down this path after her daughter Astaria is slaughtered by Horde raiders invading their village, and is aggrieved by [[BigGood Malfurion]]'s belief that [[WeAreStrugglingTogether inter-faction warfare]] is too much of a distraction from saving the world being torched by Ragnaros. The fact that Leyara is Fandral Staghelm's daughter-in-law also seems to have something to do with her downward spiral, given that Fandral had previously kept Malfurion trapped in the Emerald Nightmare and has become Ragnaros' new right-hand man.]]

* Revan is revealed to have become this for the Sith Emperor in ''VideoGame/StarWarsTheOldRepublic''; after being captured three centuries prior to the start of the game, he was kept in stasis but was able to telepathically influence the Emperor and convince him to make peace with the Republic instead of destroying it outright during the Great Galactic War. However, by the time of the game his strength had begun to fail which led to the end of the cold war between the Old Republic and Sith Empire.

* Dizzy to Testament in ''VideoGame/GuiltyGear''. More than a few bad endings has Testament reverting back to the [[HumansAreTheRealMonsters misanthropic]], [[KillAllHumans genocidal]] AntiVillain he was at the start of the series once Dizzy is harmed in any way.

* In ''VideoGame/{{Prototype}}'', Dana acts as this to Alex Mercer. In fact, the only reason the protagonist is doing what he does, such as trying to cure/destroy [[spoiler:the Redlight Virus, Elizabeth Greene, and Blackwatch]], is because he doesn't want anything to hurt her, including his own mistakes. Otherwise Manhattan would be a ultra-infected pus-filled swelling of truly gigantic proportions shortly before it wound up an irradiated wasteland. It's pretty telling that the only missions when he's not fighting his enemies or seeking information about himself are about protecting specifically her, and how rampantly the infection grows during those times.

** Some good aligned party members in ''VideoGame/DragonAgeOrigins'' can serve as this to the player. Even those playing a more "pragmatic" [[PlayerCharacter Warden]] might decide against more cartoonishly evil actions that would drive Leliana or Wynne out the the party, due to their usefulness in combat.
** Grand Cleric Elthina of ''VideoGame/DragonAgeII'' is a morality chain to [[spoiler: Sebastian. Once she's killed, Sebastian swears to raze the ''whole city'' in vengeance if Hawke chooses not to kill Anders, her murderer.]]
