“Essentally combat is an expression of hostile feelings. But in the large-scale combat that we call war hostile feelings often have become merely hostile intentions. At any rate, there are usually no hostile feelings between individuals. Yet such emotions can never be completely absent from war. Modern wars are seldom fought without hatred between nations; this serves as a more or less substitute for the hatred between individuals. Even when there is no natural hatred and no animosity to start with, the fighting itself will stir up hostile feelings: violence committed on superior orders will stir up the desire for revenge and retaliation against the perpetrator rather than against the powers that ordered the action. It is only human (or animal, if you like), but it is a fact.”

“Modern wars are seldom fought without hatred between nations; this serves more or less as a substitute for hatred between individuals.”

“They see in the population’s hostility towards the left only the hostility towards the left, not the hatred against those who are socially privileged.”

“It is to the credit of human nature, that, except where its selfishness is brought into play, it loves more readily than it hates. Hatred, by a gradual and quiet process, will even be transformed to love, unless the change be impeded by a continually new irritation of the original feeling of hostility.”

“I want to teach you to express hostile feelings without humiliating or destroying others in the process.”

“there is a fine line between sarcasm and hostility, you seemed to have crossed it. What's up?”
