Edgar Allan Poe. Ever heard of him? Some people may think that he's a disturbed poet and others may think he's a genius. Either way, he wrote a story called, "The Cask of Amontillado," that portrays just how much damage the lack of forgiveness can cause. Don't end up like the main character in Poe's story--learn to forgive. God forgave you of your sins--shouldn't you do the same?
