Decimation was considered a harsh punishment even by the standards of the ancient Rome and was abolished. The fact that you use 90% survival rate to defend the ussr just shows how delusional you bolshevik tankies are.

Mate 90% survival rates pre penicillin are incredibly common, let alone in camp prisons as a result of proper prisons overflowing due to world war 2 conditions on top of food problems. Read a book. It wasn’t until 1953 that these rates came down to standards that you’d expect when new industrial processes made penicillin widespread in the region. This stuff is extremely basic and is in practically every single book on the topic I shouldn’t have to explain it to people but none of you actually read anything.
