If we didn't have Peter, there would be no reason to care for Spider-Man. What makes him so endearing is that forever existant conflicting persona. Out of the guilt he attaches to himself for the death of Uncle Ben, he forever feels obligated to use his powers to help the innocent and fight evil. At the same time, he attempts to balance this hero life with his own life and own desires. His choice to put the responsibility of his powers and duty to protect the people from evil over his love for Mary Jane is what makes him so admirable.

Had Uncle Ben not been killed. Peter probably would've just used his powers for fun. Maybe even for his own benefit, eventually leading him down the path of evil.
