The suffering of others may warrant compassion—but only if the suffering is undeserved. Someone wrongly imprisoned can elicit your compassion — but not someone who is rightly imprisoned for a crime. To sympathize with the latter is to morally betray his victim and to subvert the principle of justice. You can commiserate with a neighbor whose house has burned down — but not if he was the one who deliberately set the fire. And certainly not if he set the fire in an attempt to burn down your house.
