Carerx
Aurora needed revenge.
It wasn't for personal reasons, well part of it was, but it was for her freedom.
She wanted to be free from this cycle of karma and hatred and the only way to be free was to either die or kill.
But she couldn't die, over and over, she will be rebirthed into the worst part of her life, where she would die and start all over again.
Her only option is to get rid of the root of all her problems, Lily.
