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.
However , it’s over, and I’ll take no revenge on his folly – I can afford to suffer anything, hereafter! Should the meanest thing alive slap me on the cheek, I’d not only turn the other, but I’d ask pardon for provoking it – and, as proof, I’ll go make my peace with Edgar instantly – Good night – I’m an angel!
In revenge a man is but even with his enemy; for it is a princely thing to pardon, and Solomon saith it is the glory of a man to pass over a transgression.
Therein lies the defect of revenge: it's all in the anticipation; the thing itself is a pain, not a pleasure; at least the pain is the biggest end of it.
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.
For one thing is needful: that a human being should attain satisfaction with himself, whether it be by means of this or that poetry or art; only then is a human being at all tolerable to behold. Whoever is dissatisfied with himself is constantly ready for revenge, and we others will be his victims, if only by having to endure his ugly sight.
A wrong is unredressed when retribution overtakes its redresser. It is equally unredressed when the avenger fails to make himself felt as such to him who has done the wrong.
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.
Hath not a Jew eyes? Hath not a Jew hands, organs, dimensions, senses, affections, passions? ...If you poison us, do we not die? And if you wrong us, shall we not revenge? If we are like you in the rest, we will resemble you in that. If a Jew wrong a Christian, what is his humility? Revenge. If a Christian wrong a Jew, what should his sufferance be by Christian example?
