Depravity

From Desmond Tutu's No Future Without Forgiveness:

This and more was the kind of testimony that devastatingly made me realize that there is an awful depth of depravity to which we all could sink, that we possess an extraordinary capacity for evil. As I have already noted elsewhere, this applies to all of us. There is no room for gloating or arrogant finger-pointing. We have supplied God with enough evidence if God had needed it to want to dispatch us all, to wipe the late clean as when He tried to make a fresh start with the Flood. But it is important to note that those guilty of these abuses were quite ordinary folk. They did not grow horns on their foreheads or have tails hidden in their trousers. They looked just like you and me. The philosopher Hannah Arendt refers to "the banality of evil" - that those involved with evil are certainly outwardly not grotesque. They are to all intents and purposes normal people like you and me.
