Peter leans further toward psychopath than sociopath, but really he's more an undetermined antisocial personality disorder, which covers a lot of ground and people to some degree or another. He's not a true psychopath, so he could potentially feel guilt for someone close to him dying. This is one of the ways he leans toward sociopath, because they can indeed care about their people to a strong degree, if only because they are theirs and no one fucks with what's theirs.

Jeff, I think, has mentioned in the past that his eyes were blue before he killed Laura. But don't quote me on that.
