My personal idea is that something very, very nasty happened to Cinder and possibly many people she loved due to one of Ozpin's very long back-catalogue of serious mistakes. It was bad enough that Cinder literally dedicated her life to destroying everything and anything Ozpin cared about. Even her own long-term survival was not so important as causing him suffering and pain.
