Spider-Man is the epitome of the difference between DC Comics and that eruption of creation that became Marvel Comics. It’s a difference that has been clouded by time.
Comics historians (of which there are too many – don’t ruin comics, comic historians, remember what happened to jazz and rock ‘n’ roll) will remember Jerry and Joe’s Superman was intended to be a bad guy. At first, that is. Then before he appeared, he became a good guy. That was the beginning of superhero comics; a guy gets super powers and “decides to help mankind” — for no apparent reason.
