1. At times, even though he is doing the right thing, Huck thinks that he is doing wrong because such were the ideas spread in the society in which he was raised. For example, when he is in the process of deciding whether to help Jim flee from the town and go to the free state, he is torn because he is concerned he might go to hell for it. However, in the end he puts his friendship with Jim above his fears, saying that he was willing to go to hell for it.
2. The duke and dauphin seem to be desperate for money. Even though they succeed in getting a lot of money by conning the whole town, they do not stop conning people and keep thinking of more ways to con people, instead of trying to make an honest living. They even try to fool a family that is in distress due to the loss of a family member in order to get their inheritance, although they fail in the end.
3. As he has his adventure, Huck sees a lot of unpleasant things in society. He says, “I never see anything so disgusting” in chapter 25 to show how horrid the actions of the two con men were. He also says that “human beings can be awful cruel to one another” in chapter 33 when he sees that the con men are being beset by a mob of people. It seems like Huck is losing his innocence as he sees the unpleasantness of the society around him and also slowly being influenced by it.
I like the examples that you have given since it revealed a lot about the characters within the novel. I agree with you that in Chapter 33, Huck is deeply influenced by the corruption of society and he begins to lose faith in it. Also, the Duke and Dauphin example displayed how corrupt the people were and how they would even try to scam poor and disabled families. I thought that these examples revealed Huck’s innocence and positive morals!
