Oren ever get her revenge?

I still don’t buy the whole idea of O-Ren joining up with Bill for the whole DIVAs thing, if he is the one who killed her father, I mean, come on this is the same girl who killed boss Mastumoto at a very young age for having her father killed, surely she would of wanted revenge on the man who’s father’s blood was on his hands, hell he even tried to kill her, indirectly, by setting fire to the house. I sure as hell would of wanted revenge on the fucker for ramming a sword through my dad’s head…Well, no, my Dad’s an asshole and I’d get enough money from his life insurance to get enough equipment to start filming movies…So, I’d thank the person who killed my dad, but anyways, I just can’t see O-Ren not wanting to kill the man who killed her father.
