Final answer:
The episode of attempting to free Jim in Huckleberry Finn contributes to Twain's theme of moral ambiguity by exploring the conflict between societal norms and personal values, as well as the complexity of Huck's own moral compass.
Step-by-step explanation:
The episode of attempting to free Jim in the chapter of Huckleberry Finn contributes to Twain's theme of moral ambiguity in several ways. Firstly, it highlights the conflict between societal norms and personal values. Huck's decision to help Jim escape goes against the prevailing belief that slavery is acceptable, forcing readers to question the morality of the institution. Secondly, it explores the complexity of Huck's own moral compass.

This nuanced portrayal of Huck's internal struggle adds to the moral ambiguity of the story.
