“We can deserve many things, such as gratitude, praise, and the kind of blame that is merely moral dispraise. But no one could ever deserve to suffer. For similar reasons, I believe, no one could deserve to be less happy.
When people treat us or others wrongly, we can justifiably be indignant. And we can have reasons to want these people to understand the wrongness of their acts, even though that would make them feel very badly about what they have done. But these reasons are like our reasons to want people to grieve when those whom they love have died.
We cannot justifiably have ill will towards these wrong-doers, wishing things to go badly for them. Nor can we justifiably cease to have good will towards them, by ceasing to wish things to go well for them. We could at most be justified in ceasing to like these people, and trying, in morally acceptable ways, to have nothing to do with them.”
