I will never understand ppl who hate/anti ANY of the members of the Gaang, or even any of the other kids. coz they are just kids. in the middle of a fucking war. of course they're gonna fuck up and make mistakes and be little shits, THEY ARE 12-16 !! ALL OF THE GAANG (including Zuko but excluding Suki) HAVEN'T HAD PROPER SOCIALISATION WITH OTHER KIDS THEIR AGE UNTIL THEY MET EACH OTHER !!
and yes, you could argue that Katara and Sokka had each other, but that's siblings and siblings are not the same as friends, and also Sokka was the only teen boy left in the tribe and I think Katara was the only teen girl too (might be wrong there tho)
you could also argue that Aang had friends before he got stuck in the iceberg so he did actually have that socialisation, but bro is fucking 12 and he was stuck in an iceberg for a hundred fucking years and had the whole avatar thing weighing down on his shoulders, cut the boy some slack ???
Toph and Zuko were both Rich Noble Kids™ so they automatically did not get proper socialisation with other kids their age. Toph was sheltered from the outside world because she's blind and a young girl, but yes she did go to that underground boxing ring but that was mainly adults, I highly doubt she was hanging about with kids there and definitely not in normal circumstances.
And although Mai and Ty Lee were there, they were Azula's "companions" (not originally meant to be friends but may have ended up as so after the war) and they weren't there for Zuko, they were there for Azula only. I'm pretty sure Zuko spent most of his time with tutors or with his mother before she left, he didn't get any socialisation with normal kids and he definitely did not get a normal childhood.
None of them got a normal childhood, so can you really blame any of them for being manipulative or assholes or doing dumb shit, whilst still being a kid/teen !!! and then being bad parents too, when they literally have no good role model to go off of (love Hakoda but bro was not there for his kids for a good couple of years and that does a lot to a kid)
edit: also Azula deserved a redemption/healing arc because she was a victim of abuse as much as Zuko was. she was in fact just a child, as much as the rest of them were, and deserved better. Thank you for coming to my Ted Talk 🙏
edit 2: Jet also deserved a chance at healing. like bro watched his village burn and was the sole survivor, he probably has mega survivor's guilt that isn't touched upon in the show, like his hate for the fire nation is pretty rational and his actions (to an extent) are justified. all I'm saying is that if he had anybody else in his corner, that wasn't more angsty, out-for-revenge teens or kids, he could have had a much nicer life. one that didn't lead him to his downfall.
