This is why the Netflix Trilogy failed.
Because it wanted to have its cake & eat it too via trying (and failing) to make a thought provoking war drama and standard magic box hunt, goodies vs baddies TF story.
And the two were at odds with each other and ultimately incompatible.

It's less about morality or ideology and more about control.

It's like WWII.
Nazism is vile.
