There is no reason to claim Montresor is insane except the element in his disclosure. He says that fortunato injured him a thousand times but doesn't give any example on how and why.Some readers conclude that he hasn't been injured and that he is delusional <span>If Montresor has not been injured, then he is insane. But Poe could not have left the question of his sanity or insanity to hinge on a few words in the opening sentence of his story: "The thousand injuries of Fortunato I had borne as best I could, etc." If Poe wanted the reader to believe Montresor is insane, his creator would have given further evidence throughout the story. </span><span />
