She gave herself two possible reasons : the first being than it was because Spring was weak and the second being than she would have been hunted her entire life. The third Reason you mentionned wasn't given directly in that speech because she never told Yang that she killed Spring to get her powers for herself.

Whatever what the real or main reason, the result is the same and it's one of the many things Raven has to made up for.
