"What evidence do you have that he was perfectly normal before he became an Islamicist?"
I concede that point of logic. He mentioned playing Grand Theft Auto and watching the Sporanos.... he SEEMED normal other other the aformentioned insane ideas.
Halt! Read your own words!...if a man has insane ideas that you recognize, he can't possibly seem normal unless he has fooled you, and you are fooling yourself!
Reason man...reason!
