The pleasure of those who injure you lies in your pain. Therefore they will suffer if you take away their pleasure by not feeling pain
TertullianThe Law found more than it lost when Christ said, โLove your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heavenโ (Matthew 5:44-45). This most important commandment summarizes in a word the universal discipline of patience, since it does not allow us to do evil even to people who deserve it.
