People are taking the "saving shigaraki" in the most literal and dumb way possible, like the whole reason he is the way he is today is because nobody saved him when he was a kid so AFO could groom him, the dude's clearly mentaly ill, deku's a hero ofcourse he would want to "save" him, idk if you're expecting this to end like naruto where sasuke is just forgiven and orochimaru gets to hang around but you know there's stuff between killing a villain and becoming friends with them, i'll be the first to say mha has been mid lately but this it's fine, it fits the narrative and the characters well y'all just don't want to take it in
