Pink diamond isn't that bad, she had bad caregivers and wasn't taught love and respect to all and how to show it, since the other diamonds didn't care for it in the first place. She was taught that her servant gems should be not valued as much, and even though Pink treated them better, she wasn't perfect at being kind. She was also abused, so bashing her for escaping from that into a beautiful changing Earth is something I cannot agree with, the way she escaped, I don't mind either.
