I think he's probably literally psychopathic. I say this as someone reading who's been reading Wikipedia about the subject for about 5 minutes. <p>My official diagnosis is that he is a Factor 1 psychopath exhibiting symptoms of Narcissistic Personality Disorder for positive effect according to PCL-R Model of psychopathy. <p>Alex behaviour demonstrates a strong correlation with the known symptoms of psycopathy including: glib and superficial charm, grandiosity, need for stimulation, pathological lying, conning and manipulating, lack of remorse, callousness, poor behavioral controls, impulsivity, irresponsibility, failure to accept responsibility for one's own actions.<p>I recommend that he eats humble pie three times a day before he gets his just desserts, after all you are what you eat. <p>I'm off to pop a few jealously tablets.
