Final answer:
Huck is horrified by Tom's plan to saw off Jim's leg in chapter 35 as a part of helping Jim escape in The Adventures of Huckleberry Finn.
Step-by-step explanation:
In chapter 35 of The Adventures of Huckleberry Finn, Huck is horrified by Tom's proposed plan to saw off Jim's leg as part of helping Jim escape. Tom's outlandish schemes for Jim's escape are influenced by the adventure novels he has read, and they reflect his disconnection from the reality and seriousness of Jim's plight as an escaped slave. Huck, despite his own initial moral uncertainties, is shocked by Tom's callousness and perceives the absurd cruelty of the suggestion.
