I've got a distant relative in Ukraine who's civilian (he's over 60 so he won't be mobilised), who's going to fight if invaders are taking his town and teaching his wife how to use a rifle. He says nothing about pride and a lot about how he never wished anything like this.
I wish I could fight for my country against invaders with a clear conscience and knowing I'm doing the right thing. I would make my family proud and make sure that they are safe.
I hope that too. I can see why you find it noble and satysfying, but I'm almost sure if you (or me) would be in such a situation satisfaction and nobility would be the last thing we care about.
It's quite sad though that we cannot find satisfaction in our ordinary lifes... Makes you think, if all this social evolution and civilization a good thing after all.
