Re: Should this Superman kill? - Part 1
He should. That will end the current Superman and transform him into something else. I'm kinda bored of the current one.
...or at least put him in a situation where he has to do it, tries it but fails. Then later he evaluates the decision, over and over and comes to the conclusion that he doesn't know what he would do if he finds himself in the same position.
Give him some realism, to offset some of his ridiculous, nonsensical powers.
