There isnt any propaganda benefit beyond “your son died hero killing many Ukraini! Here is bottle of BLYATT THATS STRONG and two hundred ruble.” The families of enlisted know their sons died in vain, but they cant do shit about it so the pundits get to say whatever they want because theyre “taking care of the family of our fallen soldiers.”
But youre right, nobody gives a fuck. Remember when the mobniks brought along mobile incinerators to the front? That was because they knew casualties would be ridiculously high, so they needed the means of destroying evidence (i.e. mobnik corpses)
No evidence is as good as never happened to Russia.
No matter what happens, so long as humans exist, they will want to fuck how they like. Its natural for a product of evolution to do it, the taboos against it exist only in our minds (aside from age limitations and informed consent; we still need to be rational) The more it gets stigmatized the worse it’ll get for people not already on top of the social heap.
