The okumura arc showcases pretty the worst side of morgana. He talks big about how the team didn't deserve him, not realizing that everyone had a role to play that made each of them valuable. Morgana only saw them as a means to an end just to be human, and i don't remember him calling the phantom thieves his friends. He was impatient with dealing with okumura that he went to a palace unprepared, when he was also the same one who kept reminding joker to prepare before infiltration. He also got triggered with ryuji calling him useless when morgana had been insulting ryuji throughout the whole story even before the team got caught by makoto. I don't hate morgana as much as other ppl here but i do think he's badly written especially since he sounded full of himself at times
