There was a bombing in Kabul as America is trying to evacuate people from Afghanistan. At least 30 people were killed. President Biden said, “To those who carried out this attack, as well as anyone who wishes America harm, know this: We will not forgive. We will not forget. We will hunt you down and make you pay.” I know that’s the type of thing that presidents say in these circumstances, but I can’t help but wonder: Why? Has any good ever come from retribution? Isn’t forgiveness a good thing?
