Yes, he tried to kill his father. He used to a clinical psychopath. But you know what? He found God, turned his life around, and even reconciled with his father. That is the power of Christ in someone's life. Doctors couldn't help him. Psychologists couldn't help. No one could help him but God. He is currently married and has two children. Quite an accomplishment for a former psychopath.
A Christian wouldn't go to a Muslim family festival and try to start trouble. He's still a psycho.
