Unpopular opinion:
Wukong did nothing wrong in LMK.
In my heart of hearts, I firmly believe that everyone like his unhinged energy right until it became too much. Like everyone enjoys his wild and free nature until that means he's so free he doesn't constantly hang out with you. Also in the canon of journey to the west Macaque tries to frame Wukong for murder after attacking tripataka. I am of the opinion that Macaque did Wukong super dirty by leaving him under that mountain because he felt abandoned. And if Wukong "killed" him for the same reason he did in the book then Mac kinda had it coming. I understand he probably felt replaced or maybe thought he was saving Wukong but come one! I just think that if Macaque can get a pass for leaving Wukong under that mountain for 500 years then Wukong should get a pass for trying to achieve his dream of being a baddy at the cost of his close friendships.
Just saying, give the man a break. He's doing better now... kind of.
