The death penalty fulfills a preventive function, but it is also very clearly a form of revenge. It is an especially severe form of punishment because it is so final. The human life is ended and the executed person is deprived of the opportunity to change, to restore the harm done or compensate for it.
I'm a fighter. I believe in the eye-for-an-eye business. I'm no cheek turner. I got no respect for a man who won't hit back. You kill my dog, you better hide your cat.
But I won't bore you any longer on the subject of old men. It won't make things any better and all my plans of revenge (such as disconnecting the lamp, shutting the door, hiding his clothes) must be abandoned in order to keep the peace. Oh, I'm becoming so sensible!
Gentleness is the ability to bear reproaches and slights with moderation, and not to embark on revenge quickly, and not to be easily provoked to anger, but be free from bitterness and contentiousness, having tranquility and stability in the spirit.
Teller contended, not implausibly, that hydrogen bombs keep the peace, or at least prevent thermonuclear war, because the consequences of warfare between nuclear powers are now too dangerous. We haven't had a nuclear war yet, have we? But all such arguments assume that the nuclear-armed nations are and always will be, without exception, rational actors, and that bouts of anger and revenge and madness will never overtake their leaders (or military and secret police officers in charge of nuclear weapons). In the century of Hitler and Stalin, this seems ingenuous.
He who is dissatisfied with himself is continually ready for revenge and we others will be his victims, if only in having always to endure his ugly sight. For the sight of the ugly makes one bad and gloomy.
Mind is a duality; it is always split. There is no single point on which the mind agrees in totality. Half of the mind will agree and half of the mind will disagree, and whatever you choose, you are choosing only the half. The remaining half is going to take revenge. The unchosen part, the left over, will wait for its chance to show you that whatever you have chosen is wrong. But it does not matter which part you choose. Choice itself is wrong.
