"I betrayed you," she said baldly.

"Sometimes," she said, "they threaten you with something you can't stand up to, can't even think about. And then you say, ‘Don't do it to me, do it to somebody else, do it to So-and-so.’ And perhaps you might pretend, afterwards, that it was only a trick and that you just said it to make them stop and didn't really mean it.

You want it to happen to the other person. You don't give a damn what they suffer. All you care about is yourself."

It was touching to see how they loved him. They begged to be shot quickly, so that they could die while their minds were still clean." (3.2.105, O’Brien)
