Have you known a "white picket" person turning bad?

Of course, yes, I do have a character like Walter White somewhat in my mind, but I want other interesting stories. The closest I can think of is my best friend with strict parents - funnily enough, a policeman and a school principal - and she went through a period of being a super slut for a moment. I guess she liked being wild for once.
