How are the duke and dauphin different in huck Finn?

In Mark Twain's "Adventures of Huckleberry Finn," the duke and the dauphin are both con men who deceive and manipulate others for their own gain. However, they differ in their backgrounds and motivations. The duke claims to be of noble descent and uses his supposed aristocratic status to justify his schemes, while the dauphin is more of a petty criminal who relies on his cunning and deceit to achieve his goals. Despite their differences, both characters ultimately serve as examples of the greed and corruption prevalent in society during that time period.
