The Deadly Sins Retribution Codes are a set of guidelines that were created by the Seven Deadly Sins in order to ensure that their members would be able to live up to their reputation as being the most deadly and feared group of people in all of Britannia. The codes state that each sin must always have a plan for revenge, never show mercy, and take whatever steps are necessary to complete their missions. While these codes may seem barbaric to some, they are what have allowed the Seven Deadly Sins to remain at the top of the food chain for centuries.
