The philosopher Simone Weil (1909-1943) wrote to Bernanos:
"Once temporal and spiritual authorities have placed a category of human beings beyond those whose life has a price, there is nothing more natural than to kill. When one knows he can kill without risk of punishment or blame, he kills; or at least one surrounds with encouraging smiles those who do kill. If by chance one experiences at first a bit of disgust, he remains silent and soon he smothers it for fear of lacking virility." 1
