This comic is a great test for someone's media literacy.

The reason Superman doesn't kill is because he doesn't need to. He's powerful enough that he can always find another way. It's the difference between killing an enemy on a battlefield or executing them after they've surrendered.

The Elite were evil because they, like Superman, were powerful enough to subdue enemies without lethal force, and chose lethal force anyone because they found it easier and it allowed them to exert undue power and influence on the world.

It's a universal allegory for bullying and misuse of power. It's something you can apply to tyrannical police states and warmongers.That's why the original comic was named after an anti-war song.

You can agree with the morality or not, but if you read the comic or watched the movie and thought "but killing bad people is a good thing!" you completely missed the point.

The point is you don't have to be a cunt, so don't be one.
