It's also possible he's just lying. If he's naturally a psychopath like you say, doesn't that mean he's predisposed towards lying? It's not like he's punished for lying or rewarded for telling the truth - we really have no way to corroborate any of this. I'm not saying your theory isn't plausible, but what makes it any more likely than him just lying?
