"Sacrifice" is a very dishonest way of referring to the mass murder Stalin routinely ordered.
You can look at the Soviet famine of 1932–1933 and argue about the real cause, and the Great Purge and crimes like the Katyn massacre had their own evil logic, but consider the Polish Operation of the NKVD -https://en.wikipedia.org/wiki/Polish_Operation_of_the_NKVD. They randomly selected Soviet men with Polish-sounding names, arrested them, and executed 80% of them.
The only thing that separated Stalin from Hitler was that Stalin sent 20% of the men to the gulag and didn't murder their families.
