No he "got away" with decades of war crimes by becoming disillusioned of the society he was born and bred in and becoming a political enemy of the state and putting his physical wellbeing at risk to free the people his country had waged war on all while mentoring the person who would take over that country and try to create a better country and a better world. One of the most poignant moments is when he says he didn't realize his visions of conquering ba sing se would be him taking it back for its own people.
Which is why this is fictional, and he's allowed to have a narrative story arc.
However, if this was a Nazi SS Officer, who fled to South America, and then went on to redeem himself by [insert narratively compelling redemption story], he'd still be a war criminal.
But again, it's a cartoon, and we don't have to treat his character as if he were an actual Imperial General commanding troops during wars of conquest, especially one from the IJA.
Pretty big difference in your scenarios there yours has a Nazi war criminal fleeing after the war is ended. Yeah it doesn't really hit as hard when it's after the fact and there's no skin in the game. A person who realizes his nation is wrong and fights to stop his Nation during the war has a lot more redeeming qualities than someone who claims to have changed his mind after the war is over and while they're running and hiding.
It wasn't a bad analogy, it was a disingenuous interpretation by other readers, like you. That or, just really ignorant of the relevant history, such as who the Waffen SS were....
So if people want to play the "what about the good Nazi" game with it, then fine, we can skip straight to the source material and inspiration for the Fire Nation: the Japanese Empire.
But again, I don't believe art has to directly reflect reality. So I don't consider this cartoon to be a war criminal, but if people insist interpreting it as a direct reflection of reality, then yes, an IJA General would be his historical analog.
Are you actually saying that a soldier who participated in the Rape of Nanking, decapitated 30 babies, but who then felt bad and deserted before the end of the war, wouldn't be a war criminal....?
I honestly think the real confusion here is that you have no idea how the Geneva Conventions, ICJ, or just the concept of war crime culpability actually work...
Hint: you're so wrong, that it's actually embarrassing. I'm cringing for you. You should delete your comment before anyone else stumbles across it...
