Why can't the protagonist just straight-up kill a bad guy? Good guys sometimes do bad things, and sometimes it's necessary.
Aang's only like 13 or something. Avatar is a progressive show, but not that progressive.
That I wouldn't mind....except we see him talk to a former Air Nomad Avatar and she basically told him to kill Ozai because it was his duty. That probably bothers me the most, the fact that he asked for advice and ignored it like a kid, just to get a gift two minutes later that allows him a third option in the final confrontation.
Yeah, pretty much this. It was just used as a Deux ex Machina to take the moral dilemma. I don't mind it so much as doing that has a pretty awesome history.
