I consider it a mark of great prudence in a man to abstain from threats or any contemptuous expressions, for neither of these weaken the enemy, but threats make him more cautious, and the other excites his hatred, and a desire to revenge himself.
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.
Men ought either to be well treated or crushed, because they can avenge themselves of lighter injuries, of more serious ones they cannot; therefore the injury that is to be done to a man ought to be of such a kind that one does not stand in fear of revenge.
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.
...If I continued to harbour any hope for music it lay in the expectation that a musician might come who was sufficiently bold, subtle, malicious, southerly, superhealthy to confront that music and in an immortal fashion take revenge on it.
To hell, allegiance! vows, to the blackest devil!
Conscience, and grace, to the profoundest pit!
I dare damnation: To this point I stand,--
That both the worlds I give to negligence,
Let come what comes; only I'll be reveng'd.
My good hoe as it bites the ground revenges my wrongs, and I have less lust to bite my enemies. In the smoothing the rough hillocks, I smooth my temper.
