WS+Charles+Manson?

It hard to say whether or not he is since he never commited any of murders. He has the mind of a serial killer, he had to be in control, a abnormal view of the world, and possibly did drugs.Manson was in and out of jails his whole life, he same attitude he had in jail he brought out into the real world. When it came when he planned the killing of the movie star and the producer, he was the one who came of with everything. The only thing he did not do was kill the people, which he his brain washed followers do for him. How do you determine whether someone is a serial killer, is it the mental or what the person does?
