Midoriya knows what it's like to be suddenly looked at as a monster because of his Quirk. He doesn't want Mob to feel that blend of fear and hatred directed at him by a crowd. It's already too late for Midoriya, but he wants Mob to have a normal kid's life, or as normal as possible. He wants him to be able to walk to class without worry.
