Okay okay, rant time.
It is a common fixture in the fandom to agree that All Might was wrong for withholding information from Izuku about the nature of OfA. Having OfA means having a target on your back for the biggest baddest awfulest scariest villain of all time.
Okay but.
All for one was supposed to be DEAD.
All Might needed someone to succeed ALL MIGHT, not someone to carry the OfA torch! He needed someone to become the NEW SYMBOL OF PEACE, which honestly doesn't have anything to do with AfO, or the origin of OfA. All Might was in fucking sweats when he realized AfO might not be dead (please refer to the episode where the UA teachers are discussed the USJ attack). All Might not telling Izuku about AfO is more All Might being unwilling to divulge his own trauma rather than withholding important information.
All 👏 Might 👏 did 👏 not 👏 withhold 👏 information 👏 from 👏 Izuku 👏 that 👏 Izuku 👏 would 👏 need 👏 to 👏 know 👏.
