When determining who should narrate the novel, Twain first considered the popular character, Tom Sawyer. Tom, after all, had garnered an enormous following from his own tale, The Adventures of Tom Sawyer. But Twain felt that Tom's romantic personality would not be right for the novel, and so he chose Tom's counterpart, Huckleberry Finn. Huck is the most important figure in Huck Finn. It is his literal, pragmatic approach to his surroundings and his inner struggle with his conscience that make him one of the most important and recognizable figures in American literature.
As a coming of age character in the late nineteenth century, Huck views his surroundings with a practical and logical lens. His observations are not filled with judgments; instead, Huck observes his environment and gives realistic descriptions of the Mississippi River and the culture that dominates the towns that dot its shoreline from Missouri south.
Huck's practical and often socially naive views and perceptions provide much of the satirical humor of the novel. It is important to note, however, that Huck himself never laughs at the incongruities he describes. For example, Huck simply accepts, at face value, the abstract social and religious tenets pressed upon him by Miss Watson until his experiences cause him to make decisions in which his learned values and his natural feelings come in conflict. When Huck is unable to conform to the rules, he accepts that it is his own deficiency, not the rule, that is bad. Abstractly, he does not recognize the contradiction of "loving thy neighbor" and enforcing slavery at the same time. He observes the racist and anti-government rants of his ignorant father but does not condemn him because it is the "accepted" view in his world. Huck simply reports what he sees, and the deadpan narration allows Twain to depict a realistic view of common ignorance, slavery, and the inhumanity that follows.
As with several of the frontier literary characters that came before him, Huck possesses the ability to adapt to almost any situation through deceit. He is playful but practical, inventive but logical, compassionate but realistic, and these traits allow him to survive the abuse of Pap, the violence of a feud, and the wiles of river con men. To persevere in these situations, Huck lies, cheats, steals, and defrauds his way down the river. These traits are part of the reason that Huck Finn was viewed as a book not acceptable for children, yet they are also traits that allow Huck to survive his surroundings and, in the conclusion, make the right decision.
Because Huck believes that the laws of society are just, he condemns himself as a traitor and a villain for acting against them and aiding Jim. More important, Huck believes that he will lose his chance at Providence by helping a slave. When Huck declares, "All right, then, I'll go to hell," he refuses his place in society and heaven, and the magnitude of his decision is what solidifies his role as a heroic figure.
