I agree with that assessment. He's clearly not big on empathy - and he's also overly fond of his own character. I wouldn't rule out some kind of psychotic episode triggering some of his decisions, as it seems too extreme for a person with a good grasp on reality. It strikes me as some kind of paranoid delusion - and that's not uncommon in a schizophrenic.
But we're dealing with a very rare case, and it's not impossible to imagine there's something in his character that we've yet to really understand.
Indeed, I wouldn't pin much hope on the experts of modern psychology.
