Fan Casting Superman in DC Elseworld's Kingdom Come Movie

Over the years, Superman worked under his secret identity of journalist Clark Kent, working for the Daily Planet, and soon fell in love and married his fellow reporter Lois Lane. However, tragedy struck for Superman, in which he was too late to save his wife and the staff members at the Daily Planet from a gas attack by the Joker. Superman arrived to find that his wife had survived the initial attack due to her concealed gas mask, but suffered a fatal injury to the skull. She survives long enough for her husband to find her dying. Using his X-ray vision, he finds that he cannot save her, but Lois makes the visibly murderous and angry Superman promise not to kill the Joker in retribution; he solemnly agrees as she dies. Trying to maintain his faith in humanity, he arrested the Joker, but only for the villain to be killed by a new superhero named Magog. Although Superman had Magog put on trial for his murder, Magog was acquitted for his cold-blooded act, as the people accepted him for permanently ridding a very dangerous criminal. This act shattered Superman's faith in general goodness over the general populace's acceptance of murder as a reasonable way to deal with the criminal problem, while overtly grown weary of superheroes like Superman whose refusal to kill allowed super-villains to terrorize the populace again and again once they escaped or were paroled. Feeling defeated by the public's perception, Superman gave up his heroic ways and retreated from the world at large by spending his time in the Fortress of Solitude, where he merely observed the acts of humankind rather than acting, until new events inspired his return less than a decade later. During Superman's absence, he intentionally failed to realize his importance as a constant inspiration/role model to other heroes.
