Who are the duke and the dauphin?

             From the middle of Huck’s journey, the duke and the dauphin join Huck and Jim. They start doing bad things; they steal, deceive people with a poor performance. They would not mind doing anything for money. They pretend to be someone else to collect money. They act like a pirate or even a dead man’s brother. They are corrupted and crazy about money. As we can see their shows that they made, they are clumsy and somewhat funny, too. They are also somewhat bold. They stay in the town for several days to get all the property from the dead man when they are pretending to be the man’s brother from England even though the people in the town might find out that they are swindlers. I also can tell that the duke and the dauphin do not have conscience or moral standards since they justify themselves and do not feel guilty when they do bad things. And they are shrewd. They make the next plan right after they meet the guy who tells them everything about the dead man and people in the town. They get all the information from him right away. Sometimes they are stupid, but sometimes they are smart. In a word, they are typical villains in the story.
