I can't even believe I have to say this, but NO, Superman would not be okay with the government asking him to become an executioner...
And how would he kill them exactly?
Beat their skulls in with his fists? Choke the life out of them with his bare hands? Burn their flesh with his heat vision?
Why are we even talking about this!
'Why do I find all of this so horrible to explore?
Sure, they are interesting questions that I don't mind seeing in an elseworlds GN. But as a theme for the film that is kicking off the tone of the whole JL, and in a film that is presenting Superman to the general audience in a way that current generations will remember him?
I just don't like it. It's dark, it's depressing and it's not how I like the tone of Superman films to be.'
