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.
Just accept that this is the direction they have taken.
Then, you can either decide this version isn't for you and stop watching. OR you can decide to enjoy it for what it is - an elseworlds tale.
'In Elseworlds, super-heroes are taken from their usual settings and put into strange times and places - some that have existed, and others that can't, couldn't or shouldn't exist. The result is stories that make characters who are as familiar as yesterday seem as fresh as tomorrow.'
