If Chapter 18 is the end of the first segment of the novel, Chapter 31 is the end of the second segment and one of the most important chapters in Adventures of Huckleberry Finn. Up until this point, the novel has wavered back and forth between the river and the shore, with humorous and cruel events constantly bombarding the reader. The conflicts of individual versus society, freedom versus civilization, and sentimentalism versus realism, as well as Huck's struggle between right and wrong, are all revealed in Huck and Jim's journey. And all come to a head in Huck's eventual decision. In the midst of these events rests Huck's inner struggle to ignore his conscience and transcend his environment.
The catalyst for Huck's action is the sale of Jim back into slavery. Ironically, Huck believes he will be shunned by his community and doom himself to literal hell if he aids Jim. Despite this realization, Huck's proclamation "All right, then, I'll go to hell," ends his struggle in a concise and powerful moment, which is the climax of the novel.
