Step-by-step explanation:
The story you are referring to is "The Cask of Amontillado" by Edgar Allan Poe. To answer your questions:
1. As Montresor starts referring to Fortunato by terms such as "the figure," "the chained form," and "the clamorer," it could indicate his psychological distancing from the victim. By objectifying Fortunato, Montresor is able to depersonalize the man he once considered a friend or acquaintance. This allows him to focus on the act of vengeance rather than the person. Moreover, this change in terminology may also serve to emphasize the confinement, isolation, and increasingly desperate state of Fortunato's plight, marking the shift in power dynamics between the two characters.
2. Once his revenge is complete, Montresor displays mixed emotions. On one hand, he feels a sense of satisfaction for successfully executing his well-planned revenge, having lured Fortunato into the depths of the catacombs and sealing him behind a brick wall. On the other hand, Montresor seems to be left with an unsettling feeling, possibly due to the gravity of his actions or a sense of guilt that arises from it. This ambivalence is seen in the line, "My heart grew sick; it was the dampness of the catacombs..."; it suggests that Montresor is denying his guilt and attributing his unease to something else.
3. Montresor may feel this way because, although he has achieved his long-desired vengeance, he has also committed an inhumane and evil act. It raises questions about his own morality and the idea of justice that he has pursued. Additionally, the satisfaction of vengeance is often short-lived, as people tend to eventually recognize the gravity of their actions and the irreversibility of the situation. Montresor's conflicting emotions imply that even in carrying out his carefully planned revenge, he cannot fully escape the consequences of his deeds on his own conscience.
