The physicist Freeman Dyson, who worked for the RAF’s Bomber Command, said years after the war, “I felt sickened by what I knew. Many times, I decided I had a moral obligation to run out into the streets and tell the British people what stupidities were being done in their name. But I never had the courage to do it. I sat in my office until the end, carefully calculating how to murder most economically another hundred thousand people.”
