What is the moral problem confronting Huck in this chapter?

Jim’s capture significantly matures Huck, for it convinces him to break with the con men for good and leads him to a second moment of moral reckoning. Huck searches the social and religious belief systems that white society has taught him for a way out of his predicament about turning Jim in. In the end, Huck is unable to pray because he cannot truly believe in these systems, for he cares too much about Jim to deny Jim’s existence and humanity.
