I have said it before; he sounds like he has serious mental problems. He has shown obvious signs of both paranoid schizophrenia and bipolar disorder. Paranoid delusions, extreme mood swings, periods of hyperactivity and depression and periods of relative normalcy, a grandiose sense of identity, pugnacious behaviour, lack of good judgement and empathy and understanding of others. And this is just what we have seen here, I would hate to be in the same house/workplace with him. He is young yet, most mental disorders only get worse with age if left untreated.
