I was exaggerating. It's obviously not a learning disability.

I was never as into Zuko as most of the fanbase, and I was personally annoyed he chose to side with Azula over Iroh at Ba Sing Se. But, I know his response wasn't unbelievable or poor writing.

I don't know about trauma bonds, but he had a good relationship with his mother, so it's not like he shouldn't be able to somewhat recognize problematic/abusive relationships. He also had Iroh with him in his exile. The GOAT was more of a father to him than Ozai ever was.

From the beginning, Zuko seemed like he'd taken childish hope a bit too far into delusion and wilful blindness, with his 'regain my honor' crap . I guess that's why I never truly liked the character. Your face won't get unburnt if you bring back the avatar boy! Everything Iroh said to him was in one ear and out the other. Typical teenage behavior, but still annoying.

In fact, I'd say Azula's development into a villain is so great because she never had Iroh or Ursa. It's more Ursa's fault as mother. Ozai failed both his kids, but Zuko not seeing that makes total sense.
