Well, Atem is supposed to be like that, he's a creature who is the only being who has those kind of powers (at least he thinks that way), In all of the freaking universes and dimensions, so yea, he's kinda cocky :P And I can pretty much understand why Isaac behaves like that, he simply has everything, he can have fun sometimes, even if it involves killing people :3
