Did Motresor commit the perfect crime ON Fortunato?

Montresor's actions against Fortunato in Edgar Allan Poe's "The Cask of Amontillado" can be seen as a meticulously planned crime, but whether it is "perfect" is debatable. He successfully lures Fortunato into the catacombs, ensuring that no one will hear his cries for help, and he leaves no evidence of murder. However, the crime is not without its flaws; Montresor’s confession years later suggests an underlying guilt, indicating that the psychological burden of his actions may never allow it to be truly perfect. Thus, while he may have executed his plan flawlessly, the moral implications and consequences complicate the notion of perfection.
