Do you think I might be a psychopath?

Well this is pretty opinionated on my part. From what you describe you seem to be rather narcissistic, however from what I understand about clinical psychopaths they don't feel almost any emotion. The shame or guilt you described seems like it goes against you being a psychopath. I'm no doctor, so don't take my word for it however. I would think about seeking help if I were in your position.
