Jimmy Savile. A good documentary with Louis Theroux. In this video all of the classic character traits of a charismatic sociopath are there.

The truth about Jimmy Savile did not come out fully until after his death. He was a very famous celebrity in the UK, and operated behind his mask of charisma for decades. This is a really good video. Unfortunately I can no longer find this on youtube so have linked to another page.
