Meditations 7:26

When people injure you, ask yourself what good or harm they thought would come of it. If you understand that, you'll feel sympathy rather than outrage or anger. Your sense of good and evil may be the same as theirs, or near it, in which case you have to excuse them. Or your sense of good and evil may differ from theirs. In which case they're misguided and deserve your compassion. Is that so hard?
