Paranoid schizophrenia too you think?. Just a tad? I know very very little about bipolar disorder but your scenario sounds closer to the above mentioned. Sorry but it sounds scary to me that a person would go to those extremes like the example you gave.
Also, is that you on that photo? If so, the first thing that came to mind was too much testosterone in the form of steroids. This will cause abnormal aggression as well. This is what happened with Benoit.
