If there was ever somebody who most closely embodied the Joker (he just wanted to watch the world burn), Charles Manson would be it. Using his twisted charm, this songwriter from California managed to create the Manson Family, a cult with which he hoped to start a massive race war. At the end of the day, he was arrested for numerous murders but somehow managed to became a pop culture icon while in jail. It sounds like something not even Hollywood could make up.
