You absolutely retarded fucking pieces of shit (yes all of you) are THE reason we cannot have quality writing on TV.
Did any of you actually pay attention to or even watch the show, or did you just read recaps of it? Aang killing or not killing is NOT THE FUCKING PROBLEM AT ALL. Yes, it would be difficult to get past S&P but there are ways it could be done - not actually showing it or saying it outright would be a big start.
No, the real fucking problem is that THERE IS NO FUCKING REASON FOR THE CONFLICT in the first place! The idea of killing Ozai wasn't even brought up until it was forced into the show in The Southern Raiders via Zuko (in an episode Bryke is alleged to have rewritten to force a specific moral via Aang and Zuko... hmmm). The Gaang had already invaded the fucking palace in the middle of Book 3 - and Aang HAD ALREADY GONE TO FACE THE FIRE LORD!
Yes, it was an eclipse - for 8 minutes! What the fuck did he expect to do there if not kill him? Or if there was a non-lethal method then, what the fuck changed in the finale!? WHAT THE FUCK WERE THE WRITERS THINKING (other than introducing yet another forced conflict, not that surprising considering how they abused Iroh of all characters to get the others where they wanted them in the finale) and why are so many the "fans" of this show so fucking stupid
