Criss Angel?

Ok, I'm sorry if this offends anyone. I believe Criss Angel is a very talented magician and all but it seems as if he's doing witchcraft and the devil's work. You know how he levitates and levitates other people and such? But HOW can he be doing witchcraft when he's always wearing a crucifix around his neck. Because you know how the Devil is very frightened of God. Help??? : /
