These people are in a warzone. Warzone = war (yeah I know thanks for the obvious)

If you’re in the warzone, and you are a Russian, with an actual army suit, you’re invading a country = you’re there to kill other people.

Now do you prefer seeing this one die or innocent Ukrainians who got invaded by Russia die?

You’re confusing morals with war. In war, there are morals, but it’s more of a grey area dude. You can’t be an absolutist.
