Charles Uzzell-Edwards is a graffiti and street artist known better known by the cheeky moniker Pure Evil. Having Pure Evil as a nickname is a bit of a joke, Charley confesses, but it's a license to have fun with dark imagery. It reflects the darkness that's in the world right now. You can't just ignore it and do a nice picture of a unicorn. Unless it's a unicorn with a rocket launcher on its head.
