History Main / MercyKillArrangement

* In the backstory for ''VideoGame/FireEmblemPathOfRadiance'', Greil became a killing [[TheBerserker berserker]] while under the influence of Lehran's Medallion. His wife Elena managed to take the medallion away from him, but took a fatal blow when Greil ran his sword into her. Horrified at what he did, Greil crippled his sword arm and hired the assassin Volke for various things, one of which is to be Greil's killer if the former ever went berserk again. Of course, that never came to be, as Greil was killed by the Black Knight. Volke kept his arrangement with Greil a secret, only telling Greil's son Ike when the latter proved mature enough to know.

* ''VideoGame/KingdomHeartsBirthBySleep'': After learning that he is some kind of weapon and is destined to fight Vanitas in order to forge it, Ventus asks Terra and Aqua to put him down the moment he does.

* ''Literature/TheWheelOfTime: Knife of Dreams'': Rand al'Thor makes this arrangement with [[spoiler:the mad memories of Lews Therin Telamon]], promising that they would die together at [[FinalBattle Tarmon Gai'don]] to convince him to [[spoiler:relinquish his suicidal grasp on ''saidin'' that threatened a SuperpowerMeltdown]].

* In ''Manga/OnePiece'', at one point during the [[WarArc Wano Arc]], Sanji's Raid Suit activates his dormant [[SuperToughness genetic modifications]] (the same ones that the rest of his [[DesignerBabies siblings]] have). However, while running away from an opponent, Sanji ends up convinced that he has struck a woman, which goes against one of his [[WouldntHitAGirl core tenets]]. Aware that his genetic modifications turned his brothers into [[EmotionSuppression emotionless]] [[LackOfEmpathy killing]] [[SuperSoldier machines]], Sanji is so horrified at the prospect of turning out like his brothers that not only does he immediately destroy the Raid Suit, but he calls [[VitriolicBestBuds Zoro]] and asks him to end his life if he should stop being human after the fight is over. Zoro realizes that Sanji is [[OOCIsSeriousBusiness being serious]] and immediately agrees to his request, telling him not to die until then.

* The ''Series/BuffyTheVampireSlayer''/''Series/{{Angel}}'' fic "[[http://www.geocities.ws/debnockels/newadditions/homebeforedark01.html Home Before Dark]]" features Holtz visiting Angel in Sunnydale while he's in the company of the Scooby Gang, allowing Giles in particular to explain the full details of Angel's curse to Holtz. Holtz ultimately concludes that it is a greater punishment to leave Angelus trapped inside Angel than to kill Angel, but makes it clear that he ''will'' kill Angelus if Angel loses his soul again. Angel accepts this promise and thanks Holtz for it, observing that his other allies would focus on trying to re-ensoul him and that could be fatal in the wrong circumstances, but he trusts Holtz's ability to kill him if required.

* In ''VideoGame/DivinityOriginalSinII'': Lohse spends most of the game trying not to succumb to DemonicPossession and can only be recruited as a companion after Act 1 if the player character agrees to kill her if she needs it.
