No, he wasn't insane, just very revengeful.
It is possible to interpret Montresor from Edgar Allan Poe's "The Cask of Amontillado" as suffering from a psychological disorder that led him to commit murder. His meticulous planning and lack of remorse suggest a disturbed mental state, which could be considered as a form of insanity. However, others may argue that Montresor's actions were driven by a desire for revenge and a calculated plan rather than true insanity.
No. Quite the contrary in fact - which promotes the reader to suspect that the narrator is insane.
It is suggested in Edgar Allan Poe's story "The Cask of Amontillado" that Fortunato insulted or wronged Montresor in some way, although the specific details of the offense are not explicitly stated. This offense likely involved a significant betrayal or humiliation that fueled Montresor's desire for revenge.
The best evidence to support the claim that Montresor is insane is his meticulous planning and execution of Fortunato's murder without showing any remorse or guilt. Additionally, his enjoyment of inflicting pain and suffering on Fortunato further indicates his mental instability. Finally, his delusional belief that the murder was justified and necessary demonstrates a clear disconnect from reality.
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.
Poe omits details in order to suggest that there are no details, which would mean that Montresor is somewhat insane for plotting a murder of someone who has done nothing to him.
Montresor is not a dynamic character in "The Cask of Amontillado" because he does not undergo any significant change or growth throughout the story. He remains focused on his revenge against Fortunato and does not show any inner conflicts or development in his personality or beliefs. His motivations and behavior remain constant from beginning to end.
