But people dislike Piper not because she is supposed to be bad, she is just badly written. As in they don't like her personality or the way she is portrayed and things like that. She isn't supposed to be evil, something Octavian seems to be. Like I said, while he isn't really a bad guy (yet), he is far from being good.
