8 Video Game Villains Who Wanted YOU To Win

Now to be completely fair to BioShock 2's Augustus Sinclair, he isn't really a villain for the overwhelming majority of the game. 

Of dubious morality at times? Sure, but he only becomes an actual antagonistic force at the tail end when he's forcibly turned into one by the real villain, Dr. Sofia Lamb, who converts Sinclair into Subject Omega - basically a souped up Big Daddy.

Sinclair has no control over his physical actions as Omega attempts to kill you, but because he still has his verbal faculties scarcely in tact, he straight up asks you to kill him and insists you shouldn't feel bad for doing so. 

Hell, after you deliver the killing shot, he falls to the ground and even thanks you for effectively putting him out of his misery. Clearly enough of Sinclair's better instincts stuck around even after he'd been turned into an elite killing machine.
