Dietrich Bonhoeffer was a prisoner at the Nazi Concentration camp at Buchenwald Concentration Camp, Dietrich Bonhoeffer’s fellow prisoner was English officer, Hugh Sigismund Payne Best. After the war, Best wrote to Sabine and Gerhard Leibholz that Bonhoeffer stood apart from most of the other inmates who often complained:

His soul really shone in the dark desperation of our prison…(we were) in complete agreement that our warders and guards needed pity far more than we and that it was absurd to blame them for their actions. 

(Ferdinand SchlingensiepenDietrich Bonhoeffer 1906-1945: Martyr, Thinker, Man of Resistance, 370)
