Personality In the original Siegel and Shuster stories, Superman's personality is rough and aggressive. He often uses excessive force and terror against criminals, on some occasions even killing them. This came to an end in late 1940 when new editor Whitney Ellsworth instituted a code of conduct for his characters to follow, banning Superman from ever killing.
