How is he an asswipe? There's an obvious larger plan, one that is revealed to the reader through internal monologue. He also needs to hide himself because he fears being used maliciously by people who would do exactly that- either through blackmail or under kindly pretenses. You gotta remember, he's practically a God among mortals. He doesn't want his waifus caught in the crossfire.
Great power, great responsibility. That sort of thing.
Also, look at that badguy's bad guy mustache. Who wouldn't want to blow up his shitty bad guy plans in his shitty bad guy face?
