When a contractor pulls the string, Ai's agents torment the victim in some appropriate manner, but it always seems to end the same way: they ask the victim if he has anything to say for himself. The victim always responds with defiance, and only then does Ai send him to Hell. So what happens if a victim does repent? We've never seen this happen, despite how horrific the torture sequences are (maybe they're magically designed to be scary but not interfere with the victim's honest response). But the agents almost always ask, so surely the answer makes a difference.
