““The passion for vengeance is a terrifyingly strong one, very easily and probably inevitably wrought up by such evidence [of atrocities], even at our distance. But however well aware I am of its strength, and that in its full immediate force and expression it is in some respects irrelevant to moral inquiry, I doubt that it is ever to be honored, or regarded as other than evil and in every direction fatally degrading and destructive; even when it is obeyed in hot blood or in a crisis of prevention; far worse when it is obeyed in cold blood and in the illusion of carrying out justice.””
