Depends on with whom you're committing adultery.
Isaac Babel was a Russian soldier in the civil war, later a writer and film producer.(RED CAVALRY). He interrogated Merien C Cooper after Cooper was shot down, for the third time, flying for the Poles in 1920.
During the purges Babel was arrested and executed in 1940. I presume the fact he was having an affair with the wife of the head of the NKVD could have been a factor.
