" In an extraordinary time, he faced extraordinary choices, and maybe some would say this means that we cannot judge him. But how can we really judge anyone except in the most extraordinary of circumstances? It’s easy to be civilized and display a patina of orderliness in calm times, but your true character only emerges in darkness and under great pressure: is it a diamond or merely a lump of the blackest coal?

Yet, my grandfather was not a monster. He was simply a man of ordinary moral courage whose capacity for great evil was revealed to his and my lasting shame. Labeling someone a monster implies that he is from another world, one which has nothing to do with us. It cuts off the bonds of affection and fear, assures us of our own superiority, but there’s nothing learned, nothing gained. It’s simple, but it’s cowardly. I know now that only by empathizing with a man like my grandfather can we understand the depth of the suffering he caused. There are no monsters. The monster is us. "
