That space the Evil One abstracted stood From his own evil, and for the time remained Stupidly good, of enmity disarmed, Of guile, of hate, of envy, of revenge .
We can more easily avenge an injury than requite a kindness; on this account, because there is less difficulty in getting the better of the wicked than in making one's self equal with the good.
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.
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.
...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.
I call Christianity the one great curse, the one great intrinsic depravity, and the one great instinct of revenge, for which no means are venomous enough, or secret, subterranean and small enough - I call it the one immortal blemish on the human race.
People should either be caressed or crushed. If you do them minor damage they will get their revenge; but if you cripple them there is nothing they can do. If you need to injure someone, do it in such a way that you do not have to fear their vengeance.
Military necessity does not admit of cruelty - that is, the infliction of suffering for the sake of suffering or for revenge, . . . nor of torture to extort confessions.
