Here I swear, and as I break my oath may ... eternity blast me, here I swear that never will I forgive Christianity! It is the only point on which I allow myself to encourage revenge... Oh, how I wish I were the Antichrist, that it were mine to crush the Demon; to hurl him to his native Hell never to rise again - I expect to gratify some of this insatiable feeling in Poetry.
Crude men who feel themselves insulted tend to assess the degree of insult as high as possible, and talk about the offense in greatly exaggerated language, only so they can revel to their heart's content in the aroused feelings of hatred and revenge.
I don't think you should support the death penalty to seek revenge. I don't think that's right. I think the reason to support the death penalty is because it saves other people's lives.
