ATLA unpopular opinion/theory
The real reason why Iroh refused to fight Ozai because Iroh knew he’d lose to Ozai.
He drones on about two siblings fighting over the throne not being the answer for peace for he would look like a traitor seeking power. But for some strange reason, he thought everyone would be perfectly ok with another younger, more hot-blooded, less experienced traitor beating up his loyal but depressed and traumatized sister for the throne.
The comics show that, surprise surprise, not everyone was ok with Zuko on the throne and Iroh wasn’t around to keep him in check even when he’s clearly in over his head.
(I could go on with everything wrong with the comics, the series finale, and Iroh’s vendetta against Azula being a very clear sign of psychological projection at best or hypocrisy at worst but now’s not the time)
We had a brief demonstration of the possibility of Ozai being more powerful then Iroh through his lightningbending during the day of black sun. He can generate lightning extremely quickly; while both Azula and Iroh, master firebenders in their own right, require at least three motions to "charge", Ozai only needs two. Also, while Azula and Iroh shoot lighting from one hand at a time, Ozai can dual-wield his lightning. His lightning is also far larger than either of theirs and pure white symbolizing that it's hotter than theirs as well.
The only thing Iroh has over Ozai is the lighting redirection thing but I bet he feels that wouldn’t be enough. Ozai was set up from the start that only a fully-realized master avatar could stop Ozai, so I don’t buy that either Iroh, Zuko or even Azula being able to stand a chance against him, otherwise he would have been dethroned a hundred times over, Iroh woulda stopped Zuko from being scarred before it even happened.
As we saw in the finale, Zuko and Azula had to go through agni kai in order for one of them to be fire lord. That leaves with the possibility that Ozai and Iroh fought in agni kai and Ozai won, which the show conveniently left that detail out.
Everyone, even his own son and brother, actually wanted Ozai dead, while I can understand and respect Aang’s refusal to go through with it since he’s already gone through a lot as it is and no 12-year-old should have to go through such filthy business, they are not wrong. It took two deus ex machinas (a lion turtle and a pointy rock) for Aang to use to take down Ozai non-lethally, without them, Ozai would have won for sure or Aang would kill him with his own lighting. But even they didn’t seem to be enough because post-series comics show that Zuko and Azula are still heavily influenced by Ozai, there’s a secret terrorist society named after Ozai and Azula is actively trying to manipulate Zuko into being like Ozai so that she could be Ozai through Zuko.
If by chance Ozai escapes prison, either by himself or his loyalists break him out, he’d have to adapt to his non-bender skills in order to live up to his loyalists expectations. His bending being stolen would no doubt drive Ozai insane and make him even more dangerous then before and what he now lacks in firebending he can make up for with literally any/every other category.
It’s commonly theorized that Iroh was prodigy while Ozai wasn’t, which implies that Ozai became the most powerful firebender there was, even more powerful then Iroh and Azula, with influence to match, through sheer hard work, self-sufficiency and indomitable will.
I once made a headcannon that the name of the founder of the red lotus, Xai Bau, was Ozai’s alias, which means Ozai was secretly the founder of the red lotus, once joined the white lotus, before Iroh, and the new Ozai society is the red lotus itself in disguise, all things that not even Azula was aware of and would not stand for them.
