Montresor’s hatred for Fortunato stems from a series of perceived wrongs and insults that Fortunato has inflicted upon him. Though the exact nature of these grievances is not fully detailed in the story, Montresor feels deeply wronged and believes that Fortunato has repeatedly humiliated him in society. This festering resentment drives Montresor to seek revenge.
Montresor details his family motto, ‘Nemo me impune lacessit,’ which translates to ‘No one attacks me with impunity.’ This highlights his belief that he must avenge the perceived wrongs done to him. Fortunato’s arrogance and disregard for Montresor’s feelings contribute to Montresor’s desire for vengeance. Therefore, Montresor lures Fortunato into the catacombs under the pretense of tasting a rare wine, symbolizing not just a physical journey but also the descent into Montresor’s intricate plans for revenge.
