This is projection. What are your sources?
Consider other sources. Noam Chomsky describes this source as "astute"

If you exchanged the words 'Ukrainian' and 'Russian', you'd have a truer picture of what is really going on. It is the Ukrainians who are getting slaughtered and have resorted to press-ganging 16 year-old children.
The "casualties per yard" metric is nonsense. If the Russians ever go over to the offensive, it might count but (according to what I consider to be reliable sources) for the present, the Russians' aim is to grind-down and destroy as many Ukrainian assets as possible. Parallels havbe been drawn to the strategy of Ulysses S Grant.
I don't see how spreading nonsense like this helps them.
