“There is no sort of wrong deed of which a man can bear the punishment alone: you can't isolate yourself, and say that the evil which is in you shall not spread. Men's lives are as thoroughly blended with each other as the air they breathe: evil spreads as necessarily as disease. I know, I feel the terrible extent of suffering this sin of Arthur's has caused to others; but so does every sin cause suffering to others besides those who commit it. An act of vengeance on your part against Arthur would simply be another evil added to those we are suffering under: you could not bear the punishment alone; you would entail the worst sorrows on every one who loves you. You would have committed an act of blind fury, that would leave all the present evils just as they were, and add worse evils to them. You may tell me that you meditate no fatal act of vengeance: but the feeling in your mind is what gives birth to such actions, and as long as you indulge it, as long as you do not see that to fix your mind on Arthur's punishment is revenge, and not justice, you are in danger of being led on to the commission of some great wrong.”
