The supermajority of Russians who are dying volunteered in exchange for (by Russian standards) large amounts of money; Russia has not resorted to large scale mobilization yet and it's illegal in Russia to send conscripts to Ukraine. The Russians fighting are psychopaths who thought it would be fun, and profitable, to kill off Ukrainians. That's probably a big part of why they fight in such wasteful ways: their commanders don't give a shit whether the men fighting live or die. They're just meat to them. And the Russians fighting don't give a shit about the people around them: they just want to avoid dying long enough to collect their financial reward.

Not all cultures or people are equal. That's leftist "defund the police" type nonsense.
