Geneforge (any of them)
You start out so humble in that game, pretty much doing as people say. By about mid game I was just killing people off for even slightly annoying me or talking down to me, haha. Geneforge is the game I go to when I want to flex my god complex.
Most of the Final Fantasy series while end game, and God of War pops to mind. Also Yakuza series, those are also brutal.

You thought you were awesome when you could piss people off on the Xbox?
That's nothing.
