Symptoms of a Psycho?

That depends on how you define "psycho". Literally, it's short for "psychopath" which is a very specifically-defined term in psychology but most people use it as shorthand for "dangerous nutter", which is less precise. The term "psychopath" itself used to be defined as an abnormal lack of empathy and an inability to form normal human attachments, both masked by an ability to appear outwardly normal. This was revised in the 1980s and mental health professionals started referring to it as "antisocial personality disorder" because (in part) of potential confusion with things like sociopathic, antisocial, amoral and asocial personalities. Whatever the precise (as far as precision goes in psychology) definition, psychopaths are rarely psychotic, despite the similarity of the words. You'd have to look up official diagnostic guidelines for more information, I think.

I think that is something you are going to want to do some additional research on... I don't think there is a simple answer to your question.
