He likes to punish simpletons, because to him, it’s something they deserve for being so gullible. So he goes and marries one, because he knows enough to know that intelligence levels are measured according to the people you surround yourself with, so he’d never have to feel bad about himself.
He cons people out of more than their money; plays their fiddle and pretends to be doing them a god-sent favour like an angel would do. He understands he won’t be liked, but it’s better than being pitied or popular, because it means fewer expectations and social norms to live up to.
He lives up to nothing but himself, and he’s fine being alone and married and smarter than everyone he meets.
