Re: Should this Superman kill? - Part 1
Killing isn't a exclusively human trait. It's a trait of many different species, including some kryptonians as well as numerous other alien races.
Superman doesn't kill, not because he's better than humans, because he's some kind of God or because Kryptonians are instinctively a better race, but because he's as good as a human can be, and he has the means (superpowers + intelligence) not to have to kill.
I think back to my father. As a farmer, he had a natural understanding for the Earth. I remember him telling me this world is capable of providing for all its creatures. Even now, with so many more people, there exists enough food for everyone.
"The problem," Pa used to say, "is people. As far back as we go, we've always had problems with sharing. Seems everyone's too busy holding on to what they've got to care how their neighbors are doing."
