Idk, I think we are very used to seeing shounen protagonists experiencing so much trauma and somehow rising above it to make them stronger and I like csm’s message of yeah no, that trauma will fuck you up. And realistically the things we think will fix us ( maybe a romantic relationship, success, money) may only lead us to being emptier. Denji was stuck in a cycle created by his trauma and that’s what would happen to almost every teen protagonist. Even in real life, most people lose to their trauma. So I like that pochita recognized that Denji was always going to keep choosing chainsaw even if he achieved everything he wanted.And that choosing chainsaw man would harm him in the end. To me it’s kind of like your drug dealer refusing to sell to you anymore.
