Answer:
Three words used in Edgar Allan Poe's "The Cask of Amontillado" that impact the story and describe the mood are "revenge," "deception," and "murder." The word "revenge" sets the tone for the story and creates a sense of foreboding. The word "deception" creates a sense of unease and suspicion, as the reader is unsure of Montresor's true intentions. The word "murder" creates a sense of horror and dread, as the reader realizes the true nature of Montresor's plan.
It is difficult to know exactly how Fortunato felt as Montresor put the last brick into place, as the story is told from Montresor's perspective. However, it can be inferred that Fortunato felt a sense of fear and confusion as he realized that he had been tricked and trapped. He may have also felt a sense of betrayal, as he believed that Montresor was his friend.
It is not explicitly stated in the story what Fortunato did to offend Montresor. However, it can be hypothesized that Fortunato may have insulted or wronged Montresor in some way, leading Montresor to seek revenge. The fact that Montresor's revenge is so elaborate and calculated suggests that the offense was significant and deeply personal.
