However, it was still a theory since he only had himself and the 4th user as examples of users who didn't die in battle. He probably felt conflicted about passing OFA to Deku since if his theory was wrong, he just sentenced Deku to a severely shortened life without telling him.

Midoriya Izuku: [is a good boy] Me:

Me on my Endeavour and Deku mentor and mentee relationship bullshit: wow thanks Deku for including Endeavour in the near and dear category, the fondness is mutual ig ???

I know people don't like the Culture Fest arc as it's relatively low stakes compared to other arcs, but Gentle Criminal was the first antagonist Deku could really sympathize with and understand, since Deku recognizes he could've become like Gentle if hadn't been so fortunate

With previous antagonists, Deku hadn't considered what made them villains and was only focused on beating them He acknowledges they hurt people, but its important he wants to understand the underlying causes now since most of them suffered due to flaws in hero/quirk based society
