Ok I kinda see your point on these parts but like here's the thing... If All Might didn't inherit Deku with One For All then what would be the possibilities of him being inherited in All For One along with Shigaraki... He could've been a Villain and he would have beaten All Might and the other Heroes if that would have actually happened in the Anime, so I think giving Deku One For All was the right choice for All Might to make.
