How is colonel sherburn like colonel grangerford?

Colonel Sherburn and Colonel Grangerford are both authoritative figures in their respective stories, "The Adventures of Huckleberry Finn" by Mark Twain and "The Adventures of Tom Sawyer" by Mark Twain. They both represent the entrenched power structures of their communities, with Sherburn embodying the Law and Order of the town and Grangerford representing the aristocracy of the South. However, while Sherburn uses his authority to maintain order and justice, Grangerford's authority is used to perpetuate a cycle of violence and revenge within his family.
