Killing and murdering can be two different things, which is why we have separate words for the actions. You're conflating the two things as though they're always the same.

To kill is not inherently to murder. Typically from a legal and moral perspective killing someone in self-defense is not murder, for example.

Armies don't generally kill in self defence, though.

Collective self defense is still self defense, but it obviously needs to be argued on a case-by-case basis.

Arguing that is something an army doesn't do. It murders when asked to murder.
