The Kamino Arc really did rewire Shigaraki’s brain as to the role of the “Demon Lord” and the function of hero society from its symbol to the lines between heroes and villains.
Shigaraki did not in any way understand that All for One harmed him at this point. He did not want to be like All for One anymore because his defeat at Kamino destroyed Shigaraki’s image of him as an all-powerful demon lord. He interpreted the defeat as All for One not having sufficient power to achieve his goals, so Shigaraki sought to surpass him.
Act One Shigaraki hated All Might largely because he believed All Might was single-handedly responsible for holding up hero society. He thought killing All Might would end everything he hated. This misconception was shattered by hero society maintaining itself after the reveal of All Might’s true form and his subsequent retirement. Shigaraki wanted to kill the Symbol of Peace, so he didn’t bother to attempt to kill the retired Yagi Toshinori. His failure to recruit Bakugou also convinced him that it was impossible to get heroes to leave hero society. As a result of these challenges to his simplistic Act One worldview, Shigaraki’s goal in Act Two gradually mutated into just destroying everything.
Rahhhh this is such good character analysis. I’m gonna go to bed so I can write abt it in the morning. I’ve never thought abt it like this before
