You are talking about people who have been consuming agitprop their whole life about why they should do this kind of thing for their country, and there’s a good chance they were conscripted against their will, where the choice was go to war or die in a gulag. In the same way I wouldn’t blame every American that went to Vietnam for the pointlessness and atrocities of that war either. (though I may be biased on that, my grandfather was drafted and was a cartographer during the war)
