Considering Izuku didn't have a quirk in which you could call 'humane', he could never really imagine the lifestyle where he could be a hero. He could never stoop so low as to become a villain either. So I guess he's just...there. Living as an abnormal civilian who has also been considered like a son to Aizawa Shouta. Though he would never trade anything in the world when it came to his legal guardian, Izuku really can't stand his own quirk. He'd do anything in his will power never to have to hear it again.
