Obviously nothing is wrong with him or he's just really good at fooling you. Only way to tell is to **** him off. Do everything you can to make him mad and if nothing works.. Get away from him! I've seen those people who seem really nice and never get upset. They're the ones that snap one day and kill everyone due to implosion.

Btw sociopaths have emotions. We just lack remorse. If you met me you would never guess I was sociopath. We aren't all monsters bent on destroying other people. I was just born without remorse.
