No, Fortunato never fully understands why Montresor hates him. He is lured into the catacombs on the pretext of tasting wine, only to be betrayed and killed by Montresor in Edgar Allan Poe's short story "The Cask of Amontillado."
The story does not say why Fortunato insulted Montresor. In fact, there is doubt that there ever were any insults at all. They might have simply been a product of Montresor's imagination
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.
Montresor is an unreliable narrator because there are indications that he is either insane or the possessor of an overactive imagination. The indications come from Montresor's words and Fortunato's actions. Montresor begins the story by telling that he has suffered a thousand injuries at the hand of Fortunato , but now Fortunato has also insulted him. For that, Montresor seeks revenge and plans to murder Fortunato. The problem is that Montresor gives no details of these injuries or insults, leaving the reader to wonder if he is imagining all of it. Another indication that no such behavior ever occurred is found in Fortunato's behavior when he runs into Montresor at the carnival. Fortunato is friendly and gracious. He offers to leave the carnival to help Montresor test this Amontillado Montresor says he might have. In the cellar Fortunato suspects nothing untoward from Montresor even though they discuss Montresor's family motto which is that they will not allow anyone to insult the family. Surely, if Fortunato had acted so badly toward Montresor he would not have offered his help and would not have been so blind to the possibility that Montresor would uphold the family honor deep down in the cellar where Montresor could exact revenge with no one knowing about it. And that is just what happens.
In the opening line, Montresor states that he has suffered a thousand injuries at the hand of Fortunato but now Fortunato has also insulted him and this is too much to take, so Montresor plots revenge. There is an indication that Montresor is insane because there is doubt that Fortunato has ever injured or insulted Montresor at all. Montresor does not describe a single incident of injury nor does he describe the insult that supposedly has pushed him over the edge. Why would Montresor suffer a thousand injuries but plot revenge after only an insult? Aren't injuries more serious than insults? Wouldn't sticks and stones break Montresor's bones but words can never hurt him? Why plan to murder someone after an insult but not after all those injuries? Later when they meet at the carnival, Fortunato is very friendly toward Montresor. He hardly acts toward Montresor like he has injured him a thousand times and has just recently insulted him. Wouldn't Fortunato have said something to Montresor about the insult or about all those injuries he has laid on him in the past? Darn right, he would have, but he doesn't. Fortunato acts like they are the best of friends. Not only does Fortunato act friendly, but then volunteers to leave the carnival to go with Montresor to his home to test the Amontillado. Sure, Fortunato's vanity in being a connoisseur is part of that willingness, but surely, he would not have been so cheerful in doing Montresor such a favor. Finally, Fortunato, this supposed enemy of Montreesor goes down into Montresor's cellar without the slightest bit of trepidation about being all alone in the dark cellar with someone he has supposedly injured and insulted. Fortunato's action completely belie the idea that he is an enemy of Montresor. The one conclusion the reader can draw from the contradiction between Montresor's words and Fortunato's actions is that the injuries and insults Montresor mentioned are all in his head and that he is quite insane.
The hook is knowing that Montresor plans on exacting the perfect revenge on Fortunato and reading further to see if he actually does it. Montresor states in the opening that a wrong is not avenged unless the avenger is not caught and that the person who committed the offense must know he is now paying for that offense. The reader gets hooked into continuing into the story to see if Montresor will actually commit the perfect crime and how he will do it.
The resolution in 'The Cask of Amontillado' occurs when Montresor has finished bricking up the niche in which Fortunato is chained and leaves with the salutation "In pace resquiescat." This is where the conflict between Montresor and Fortunato is settled for good and it is clear that Montresor has achieved his plan to exact the perfect revenge on Fortunato.
Montresor states that he has suffered a thousand insults and injuries from Fortunato and that he must have vengeance against him, so he planned Fortunato's murder. No details of these insults and injuries are ever given, leading the reader to wonder if they are all in Montresor's mind. Perhaps they never happened at all. This is reinforced by the fact that Fortunato greets Montresor in a very friendly way, offers to help Montresor decide if the wine is a true Amontillado and persists in going through the catacombs despite the dankness of the passageway. Even though Fortunato is driven by his own conceit as a connoisseur of wine, these actions are hardly the actions of a person who has committed thousands of insults and injuries.
It is about a man named Montressor, who was insulted by another man named Fortunato, who is equally as rich as he is. He decides to take revenge on Fortunato by using Fortunato's weakness ---- his pride in being an expert on wine. He tells Fortunato he has a bottle of Amontillado but isn't sure if it's real or a fraud. Montressor brings Fortunato into his basement where all of his dead ancestors are buried and where his wine cellar is. Montressor repeatedly says that Fortunato is too sick to go into the basement and insists that another friend can go down into the basement to check if the Amontillado is real. Fortunato refuses and is tricked into a corner deep in the basement. Montressor chains Fortunato to the wall and builds a brick wall sealing Fortunato in the basement. Montressor's code of arms says says "We will not be without revenge." Fortunato dies behind the wall and is never found again. Supposedly it is a partially true story because during Poe's era, they found a body chained to a wall in a wine cellar in the same area this story took place.
Fortunato is deceived into entering a small room in the catacomb-like cellar in Montresor's house, where he is chained to a wall and sealed in when Montresor builds a brick wall across the entrance to the room. According to Montresor, Fortunato has rested in peace there for the past 50 years.
Montresor walls up Fortunato alive in a niche in the catacombs. Just before Montresor finishes the wall he tosses a burning torch through the gap. It ends with the revelation it has been 50 yrs since the incident and he has never been caught and Fortunato still hangs from the chains in the niche where he left him.
Yes, it is heavily implied that Fortunado dies at the end of "The Cask of Amontillado." After being walled up in the Montresor family catacombs by the narrator, Montresor, there is no indication that Fortunado is able to escape.
His motive is revenge. In the short story "The Cask of Amontillado' by Edgar Allan Poe, Montresor explains his motive for revenge against Fortunato thus: THE thousand injuries of Fortunato I had borne as I best could, but when he ventured upon insult I vowed revenge. You, who so well know the nature of my soul, will not suppose, however, that I gave utterance to a threat. At length I would be avenged; this was a point definitively settled - but the very definitiveness with which it was resolved precluded the idea of risk. I must not only punish but punish with impunity. A wrong is unredressed when retribution overtakes its redresser. It is equally unredressed when the avenger fails to make himself felt as such to him who has done the wrong.
