What is the internal conflict developed in this chapter

Each time Jim mentions how soon he will be free, Huck feels increasingly guilty. Huck knows that helping Jim escape is breaking the law, but Jim is also his friend. Thus, Huck is trapped in a difficult moral dilemma. After a great deal of reasoning, Huck realizes he will feel possibly even worse if he turned Jim into the authorities, and decides it would be best to let him escape.
