Look at what Aleksandr Solzhenitsyn wrote about political interrogations of orthodox Communists in the time of Joseph Stalin:
If you are an orthodox Communist, then another orthodox Communist will sidle up to you, peering about with hostile suspicion, and he’ll begin to whisper in your ear so that the uninitiated cannot overhear:
“It’s our duty to support Soviet interrogation. It’s a combat situation. We ourselves are to blame. We were too softhearted; and now look at all the rot that has multiplied in the country. There is a vicious secret war going on. Even here we are surrounded by enemies. Just listen to what they are saying! The Party is not obliged to account for what it does to every single one of us [emphasis added] — to explain the whys and wherefores. If they ask us to, that means we should sign.”
