How to Deal With a Psychopath

The advice is to not give them what they want, which i imagine would make a psychopath angry. They may just move on to find somebody else who's more easily manipulated. It's possible that you might really their attention, in which case your're not going to be very happy with having to shed that person. I can't help but wonder if once we know how to treat psychopathy, that we will view them much differently, and maybe even with sympathy. But that's a new thought.
