One of the toughest feelings to shake off is the feeling that when someone does you wrong, then they need to be punished as brutally as possible. As humans, it is our natural instinct to want to extract revenge on those who have wronged us. This instinct dates back thousands of years and was the culprit for many wars that have taken place over the course of our human history. While it is okay to feel burned, scorned, and betrayed by others, society these days is trying to teach us that if someone wrongs us, it is best to forgive them and leave their retribution up to God or fate.
Some people may accept that be able to live happily and move on with their lives, but there are others who would rather leave the retribution of their enemies in their own hands and move on with God watching over them. That doesn’t satisfy everyone.
