conflict: waht does the king and duke selling jim signify? how does this event advance hucks moral conflict? what is the outcome of this conflict?

In Huckleberry Finn Twain frequently draws links between Huck’s youth & Jim’s status as a black man: both are vulnerable, yet Huck, because he is white, has power over Jim. The duke & the dauphin are a pair of con men whom Huck & Jim rescue as they are being run out of a river town. Huck quickly realizes the men are frauds, but he & Jim remain at their mercy, as Huck is only a child and Jim is a runaway slave. THe Duke and Dauphin are really no different than the people they try to con. THey are filled with the same carelessness for humanity and racial attitudes of the time. THey are in fact worse because they seem friendly with Jim until they find the need to sell him. Huck rethinks what society has taught him as right or wrong in regard to race.
