Montresor hates Fortunato because somewhere in the past, he insulted Montresor and his family, and the Montresor's family motto is that no one can hurt the family and get away with it.
Montresor feels sick at the end due to the guilt and remorse he experiences after he walls up Fortunato in the catacombs to die. This overwhelming guilt weighs heavy on him, causing physical and emotional distress.
There are only two characters: Montresor and Fortunato the only other people named in the story are Luchresi and Lady Fortunato, who takes no active part in the plot.
Montresor feels that he's gotten well-deserved revenge. Fortunato wronged him in the past, and Montresor even tells him that his family motto is, basically, that no one gets away with wronging anyone in his family. So, he feels justified in that Fortunato deserves the damage done.
Fortunato first realizes that Montresor plans to harm him when he is being led deep into the catacombs and notices Montresor's silence and unusual behavior. At that point, he starts to feel uneasy and senses that something is amiss.
Because he felt that he should be the one to kill Fortunato after the fact that he was bullied by Fortunato
In Edgar Allan Poeâ??s â??The Cask of Amontilladoâ??, the narrator Montresor never reveals the egregious affront that Fortunato committed against him. Details are provided on the conditions in which the revenge must be carried out. However, even when Fortunato is being walled up, Montresor does not reveal the reason and Fortunato does not ask.
Not knowing what Fortunato did to Montresor heightens the horror of the story because the reader is never certain if Fortunato ever did anything wrong against Montresor that was deserving of such revenge. If Fortunato's so-called injuries and insults had been laid out for the reader to see, the reader would either sympathize with Montresor or with Fortunato depending on the reader's own point of view. Not knowing what was ever done, in deed if anything had even been done, leaves every reader wondering if Fortunato's death is just a terrible mistake by a madman.
Luchesi is another wine expert.He was never ''in'' the story,but his name was used to lure Fortunato into the catacombs. Basically he is a wine merchant to make Fortunato jealous and feel undermined. Luchesi served as a tool of manipulation for Montresor. Montresor knew that Fortunato was very proud and would not appreciate a different wine connoisseur's wisdom being esteemed more. Montresor mentioned the Amontillado wine, which he wanted examined, and then prompted Fortunato into coming with him by mentioning Luchesi.
Some people may feel remorse or guilt about killing bugs, while others may not. It ultimately depends on individual beliefs and values.
