Well, if we establish personhood as a two-sided social contract then I would argue that psychopaths are those who view it as a one-sided social contract, seeking to maximise the rewards for themselves without maximising the rewards for the other side of the interface. Though, you could argue that this is really just another way of saying it's a hack, which is an intriguing way of looking at things.
