" war. There was now no point in a war that might once have been justified as a search for free subsistence and living space – it had degenerated into vast, inhuman mass slaughter, negating all cultural values, and it can never be justified to the German people; it will be utterly condemned by the nation as a whole. All the torturing of Poles under arrest, the shooting of prisoners of war and their bestial treatment – that can never be justified either. "

― Władysław Szpilman , The Pianist: The Extraordinary Story of One Man's Survival in Warsaw, 1939–45
