"I just feel so angry... all of the time... and what if after everything I've been through, something's gone wrong inside me? What if I'm becoming bad?" Who said it: Harry Potter Book/film: The Order of the Phoenix Everyone goes through a sort of rebellious phase as a teenager where you're more tempted to do bad things, but it all depends on if you actually go through with them or not. If Harry, who was a horcrux, and had his family and friends killed by Voldemort didn't turn bad, then you have no excuse.
