Superman, for lack of a better term, is a god, but he doesn't require anyone to worship him. He helps those in need regardless of wether they love him or not. He also allows other "gods", i.e. The Justice League, to exist. They could stand against him should he decide to become a tyrant. Superman also allows people to be critical of him. If someone like J. Johanna Jamison were to publicly criticize him, he would take that as a sign that he must stay on the straight and narrow in order to keep the trust people put on him. Superman would also not let evil things happen, and if they do he would feel horrible about it because he could have done more to prevent the loss of life. Should there be an afterlife that Superman was in charge of, he would make sure that only those who commit unspeakable acts of evil would be sent to hell, not those who just didn't like him or those who were not perfect. ~James Kenny
