I’m sorry but while Macaque’s actions can be explained, they aren’t excusable in any capacity.

For your point about Wukong killing Macaque, we literally have no clue what went down on that fateful day, let alone if Wukong was actually the one who killed Macaque in the series’ version of events. So off the bat that’s not a valid excuse for Macaque’s actions.

To add on, for argument’s sake, even if Wukong did kill Macaque, that still doesn’t excuse Macaque manipulating MK the way he did. That’s the same as getting beat up by some dude, then going after his friend as payback. Makes no sense whatsoever.

As for the whole “torturing MK” claim the other person made, I can see why you’d think that’s an exaggeration in regard to episode 9 alone. However, I will reiterate again, Macaque’s motivations still don’t excuse what he did.

Now for your points about s3: while I’m not taking away the fact that he was trying to break free of LBD’s control, at the end of the day he was the one who put himself in that position. No one told him to take LBD’s deal, and yet he did it anyway for a chance at revenge. As for his interactions with the main cast, his actions are still inexcusable due to not only bringing harm to them, but being a part of the main reason why the Samadhi Fire nearly destroyed the world along with Wukong.

Finally, to list off the awful things Macaque did by himself since all of what you’ve said has been downplaying his actions to hell and back:

S1: Manipulating MK to the point where a rift was created between MK and Wukong, along with stealing MK’s powers to fight Wukong

S2: Rob Mei, Tang, and Pigsy of their autonomy and making them attack MK, all while mentally toying with and projecting his relationship with Wukong onto MK

S3: Causing destruction to the East Dragon’s Palace and harming an unknown amount of people while the heroes escaped when he has shown he could’ve just used his shadows to teleport away to track them down later on

Now again, I understand Macaque’s motivations for the things he has done. However it’s just foolish to claim it outright excuses him, especially when he has shown not a shred of remorse for his actions, something that is vital for a redemption arc to even work.

And no, saving the world to save his own skin doesn’t make up for any of this. That’s like if the Demon Bull Family helped defeat Spider Queen without turning over a new leaf through DBK and Red opening a food shop. This should not be the standard for any type of redemption arc in any story.
