personally from seeing his character in both the manga and anime I think aizawa would have said the same thing as all might because all might only said that as from what he could see and was told by him izuku was just a scrony teenager with no power or real way of defending him self and said the best thing for him at the time and with aizawa being the logicel thinker he is would have said the same maybe not as bluntly but all around the same.
I think they need to react to the alternative universe where izuku snapped in middle school and droven his brother to insanity used to be called you want monster I b will give you monster izuku goes on a killing spree and the villians learns the hard way why they ahouldnt betrayed him with 2 of them dead and shaggy not wanting to escape too scared izuku would get him and poor katsuki gets the sane treatment
