Lex Luthor in DCU comics. I argue that the same logic laid out in Superman Red Son applies to all superman. Where he crashed on earth didn't change his affect on mankind.
Suicide Squad (the comic) doesn't quite fit the OP's request but it's so good I feel it deserves an honorable mention here.
I would say that Lex Luthor is more of a villain who sees himself as the good guy. He thinks he is humanity's savior from what he perceives as an alien threat. Whether he is evil or not depends on the actions of Superman.
