Putin is cleaning Russia of its undesirable population while stealing land from its neighbours. I suspect there are many moscovites that think this is a great thing.
Casualties are how most militaries think about losses. A soldier in a hospital is just as bad as a dead soldier from the perspective of force management... Neither can participate in combat or act as a reserve. In fact, a wounded soldier is ofter worse than a dead one during combat because there's likely 2-3 other soldiers trying to save them.
Interesting how? It's a literal 50 tons of dead people. I think it's more sad than anything.
Russia reports one eighth of this number officially. BBC claims to have verified these people by name, by looking at cemeteries and stuff, so obviously the real count is going to be higher. Also, Ukraine reports casualties of "the invaders" who might be from the Donetsk-Lugansk militias, that is not included here.
