This scene right here, in my opinion, is the most important scene of the entire series. An old woman who is no hero and had "no obligation" to help that kid decided to do so anyway, and with that single action, changed his future entirely. "If only someone, anyone helped me that day..." - Shimura Tenko This proves that anyone can be a hero. Anyone has the power to do things with much greater impact than we can even imagine. Like a butterfly effect. Deku and Uraraka reacting to that scene is also super important... they're the ones who tried saving the villains that were neglected when younger (Tenko and Himiko) but sadly they were too late. For them, seeing people being there, finally extending a helping hand just in time is the proof that society is learning and healing. This one scene is the whole essence of what My Hero Academia wants to teach us viewers. You can be a hero.
