"I won't kill you, but I don't have to save you."
- Bruce Wayne, Batman Begins
He doesn't think he can begin to count the number of times he has changed his mind about Jill, but the time that changes his mind for good is when he sees Jill staring her down in the sights of her pistol. He knows that if he were a real spy he'd knock her out, or take her gun away, but instead he does something that would normally make him feel sick, but to save her it just seems natural. When the cuffs lock on Jill's hands, he should probably hate himself for it, but he doesn't.
