"Our sense of the horror and dreadful atrocity of such conduct, the delight which we take in hearing that it was properly punished, the indignation which we feel when it escapes this due retaliation, our whole sense and feeling, in short, of its ill desert, of the propriety and fitness of inflicting evil upon the person who is guilty of it, and of making him grieve in his turn, arises from the sympathetic indignation which naturally boils up in the breast of the spectator, whenever he thoroughly brings home to himself the case of the sufferer."
— Smith, Adam (1723-1790)
