** “Really Keith? You’re ''really'' going to give me this speech on how killing you suddenly makes me just as bad as you? Oh come on now! So let me get this straight... ''You'' were responsible for thousands of deaths of innocent civilians, if not ''millions'' of them, ''You'' have [[CruelAndUnusualDeath gruesomely]] [[ColdBloodedTorture tortured]] a good number of civilians, ''You'' [[TheUnapologetic have made no attempt to repent for your reprehensible actions whatsoever]], ''You'' have committed so many [[MoralEventHorizon diabolically evil acts]] all [[ForTheEvulz for fun]], and now the moment ''I'' kill you for the greater good[[DramaticPause …]]makes ''me'' '''''[[SuddenlyShouting the bad guy here?!]]'''''”

** 7. Bob explains to Alice that Keith was defeated a number of times before, then [[VillainsWantMercy talked the captors into sparing him]] and promised to change for better -- only to [[ILied drop his part of the deal]] [[FalselyReformedVillain when he was no longer at their mercy]]. Even if Keith was jailed, [[MightAsWellNotBeInPrisonAtAll he would run his criminal operations from prison]] and later got off the hook [[BailEqualsFreedom one way]] [[MiscarriageOfJustice or another]]. Therefore, Bob realized that Keith was BeyondRedemption. As for the blank expression while shooting Keith... well, Bob is quite [[TheStoic emotionally restrained]] anyway, but he had to strenghten himself into killing Keith and [[ItNeverGetsAnyEasier wouldn't consider that otherwise]].
*** To further hammer his point home, Bob calls the police to issue an arrest for himself, charging himself with murder/manslaughter. He'll serve his sentence faithfully to prove that he is not like Keith, if he commits a crime, he will undergo the proper punishment for it. Even if it's death sentence.

** "But I ''do'' want to be like him... ''[[DeathSeeker De]]''''[[TakingYouWithMe ad]]''." ''(cue triggered grenade)''
** "[[ShutUpHannibal I've heard this one too many times. So let me make it clear now.]] Like you, Keith, I ''am'' a killer. [[NotSoSimilar Unlike you]], I'm not a stark-mad [[LackOfEmpathy empathy-free]] maniac who [[TheSociopath only sees people as targets for killing]]. [[PreMortemOneLiner Now, goodbye.]]" ''[[BoomHeadshot (blam)]]''

* '''Played For Laughs''': Keith [[DrivenToSuicide offs himself]] during Alice's speech [[SillyRabbitIdealismIsForKids simply to avoid]] [[GoodHurtsEvil hearing her idealism]].

** "[[CashCowFranchise Our series is extremely popular]] and we need to justify [[StatusQuoIsGod the status quo of]] [[JokerImmunity surviving villains]]."

** There are plenty of heroes who want to defeat Keith [[WeHaveReserves and their life]] [[MenAreTheExpendableGender isn't that important,]] so [[StatusQuoIsGod the battle between them and Keith still endlessly continues.]]

** [[SarcasmMode "Ah yes, because executing an unrepentant genocidal maniac who intends to continue his reign of terror and bloodshed if left unchecked is totally equivalent to being thw unrepentant genocidal maniac itself. Totally."]]
