I mean both Zuko and Iroh teamed up with Katara and Aang
Doverstar Same answer as last time! I think even if Zuko had had Uncle Iroh with him when he joined the Gaang if he'd joined in Crossroads of Destiny, Iroh is not the special sauce that changes Zuko. Iroh helps, but Zuko makes these decisions on his own. And we all know he's no stranger to stabbing his wonderful uncle right in the emotions if he's riled enough. Eventually, Zuko would have chosen Azula and the Fire Nation with the right amount of manipulation, because if he'd joined the group in Crossroads of Destiny, Iroh or no Iroh, he wouldn't have learned and done what he'd needed to as a character yet to really choose good and be that person he needed to be.
