Well... I've been to worlds with gods. Hades is a huge jerk, for the record. Doesn't mean they could deal with the bad guys that came from a different world. Demyx did steal something pretty important from them, after all.

Don't think I've been to a world that has devils or angels, though. Maybe Pain and Panick, but I dunno if they count. Hard to say, since not all worlds have the same things in them.

But you telling me that the right options is to break the rules? Sometimes it's not so much what you're supposed to get done, but how you do it. What happens if someone gets hurt or places are wiped out just because you thought you were doing the "right option?"
