The unforgiven can lead to a family feud, and that leads to excommunication. Perhaps the most infamous feud in the history of the U.S., the The Hatfield–McCoy conflict is now an icon of American folklore. The Hatfields, of West Virginia, were led by William Anderson "Devil Anse" Hatfield. The McCoys, of Kentucky, were under the leadership of Randolph "Ole Ran'l" McCoy. If your family it not forgiving, it will explode, and the fire can last for generations.
