It is apparent Huck dislikes these Kings, and assumingly all whom are considered part of “high society”.
While staying with Huck and Jim, the “king” and “duke” let them in on a number of scams which they play to rob the uneducated of their money, exposing Huck once again to the evil side of civilization. Through their recitation of classic plays and somewhat advanced knowledge of the world, the King and Duke trick unassuming people into trusting them and paying for fake newspapers, plays, and many other scams. Huck goes along with this, but he is impacted by the malicious behavior of the King and Duke. Huck can see that the King and the Duke are using their education, or civilization, for evil, once again suggesting to Huck malicious behavior is the direct result of civilization. At the end of Huck's time on the raft, the two con men decide to make a quick buck again, and sell Jim for $40 without telling Huck. When Huck learns of their trick, he sits down and cries, thinking to himself how these “scoundrels” could have done such a thing. Jim was Huck’s best friend, and they sold him away like it was nothing. This final impression the King and the Duke made on Huck was an everlasting one, and undoubtedly impressed a feeling of disdain for high society within
