The residual magic from the scar makes Harry so intelligent that he has adult level thinking at the age of 15 months. Unable to suffer the abuse under the Dursleys, Harry runs away when he is 2. He becomes a muggle crime lord and forms his own gang from scratch. He also saves children from abusive environments. He does not attend Hogwarts till fourth year. This is full of violence.
