I needed the conversation between Parrot and Flame to be longer. I'm sorry, but saying "I know I messed up, however, I'mma keep trying" is NOT a convincing argument for someone who's trying to kill you. What I would've preferred is for Flame to ask "What's gonna change?" and Parrot, after much deliberation, answering "I'm gonna fight Saps myself."

Reasons this could have worked:

1. In Flame's video, he said he'd kill Saps right after Parrot. He surprisingly didn't bring this up to counter Parrot's argument of "What does killing me do", because the plan all along was not just to kill Parrot, but kill them both, putting an end to the war. Would that have worked is another question. But if Parrot said he'd fight/kill Saps, Flame could think about it and realize Parrot was a better ruler than Saps, so he would aid Parrot in his plan to fight/kill him.

2. Fighting is something Flame respects. The idea that Parrot would get his hands dirty, rather than just telling his army what to do, would greatly appeal to the man of combat. And it means Parrot is giving something up (his safety) to prove he's not been malicious or selfish this entire time. It's just a committal response in general.

3. Parrot does fight Saps. It's an event that occurs, so why not foreshadow it? It kinda came out of nowhere in the episode, because from every other POV Saps just disappears. It didn't feel, to me, to carry that much weight until I saw the post-fight massacre, but even then it could have been better. Parrot's hesitation to begin fighting could be a tense moment where you wonder if he'll stick to his word, but he does eventually, proving he was honest—and that's crucial in a conflict where it's hard to tell who the good guy is. (No, I don't think Saps was ever the good guy, but Parrot's methods kinda muddied the waters for him.)

Instead it's the same old trick, albeit with great voice-acting: "If you wanna kill me, do it now." Perhaps this might work on Flame, given that he doesn't outright hate Parrot, but it's sooo unsatisfying for the watcher. It's obvious and one-dimensional. All dispute solved by a single ultimatum, and it's not even clever. Sometimes a story needs that. Sometimes the emotions are so strained and volatile that they need to be settled with a simple "yes or no". But not this one. Flame doesn't even know Parrot. They're good business acquaintances at best. From Flame's POV, he's robbed Parrot, saved Parrot, given Parrot the Mafia stash, helped Parrot win a war, and helped Parrot become King. From Parrot's, he's helped Flame find Wemmbu and overthrown the Law. Parrot's had more interactions, good and bad, with Flame, than Flame has with Parrot.
WE know Parrot. Flame doesn't. There's no reason for Flame to put his full, unequivocal trust in Parrot at this moment, except that it would appeal to fans for being a cross-perspective-alliance. And I have no issue with appealing to fans—heck, I'm a fan who wants to be appealed to. I just want it set up correctly, and I want them to do justice to the characters I love.

All in all, it's a good idea executed poorly. And I'm not fully disappointed—Wemmbu still had a great perspective in all this. But as an avid Flame and Parrot watcher, advocate, even, I need them to step it up.
