“Wars are scattered all over the earth with the bloody horror of camps. The whole world is wet with mutual blood. And murder–which is admitted to be a crime in the case of an individual–is called a virtue when it is committed wholesale. Impunity is claimed for the wicked deeds, not because they are guiltless, but because the cruelty is perpetrated on a grand scale.”

— St. Cyprian, Bishop of Carthage (died 258 AD)
