Huck’s youth is an important factor in his moral education over the course of the novel, for we sense that only a child is open-minded enough to undergo the kind of development that Huck does.

Huckleberry Finn is full of malicious lies and scams, many of them coming from the duke and the dauphin. It is clear that these con men0s liues are bad, for the hurt a number of innocent people. Yet Huick himself tells a number of lies and even cons a few people, most notably the slave-hunters, to whom he makes up a story about a smallpox outbreak in order to protect Jim. 

Jim spouts a wide range of superstitions and folktales. Whereas Jim initially appears foolish to believe so unwaveringly in these kinds of signs and omens, it turns out, seriously, that many of his beliefs do indeed have some basis in reality or presage events to come. 

Huckleberry Finn is full of people who base their lives on romantic literary models and stereotypes of various kinds. Tom Sawyer, the most obvious example, bases his life and actions on adventure novels.
