His over-sensitivity becomes in this story the ultimate cause of his obsession with the old man's eye, which in turn causes him to murder the old man. His sensitivities allow him to hear and sense things in heaven, hell, and on earth that other people are not even aware of. This type is found throughout all of Poe's fiction, particularly in the over-wrought, hyper-sensitive Roderick Usher in 'The Fall of the House of Usher.' As with Usher, the narrator here believes that his nervousness has 'sharpened my senses - not destroyed - not dulled them.' Thus, he begins by stating that he is not mad, yet he will continue his story and will reveal not only that he is mad, but that he is terribly mad. The story begins with the narrator admitting that he is a 'very dreadfully nervous' type.

And as noted in the introduction to this section, this story shows the narrator's attempt to rationalize his irrational behavior. In a sense, the narrator is worse than a beast only a human being could so completely terrorize his victim before finally killing it, as, for example, the narrator deliberately terrorizes the old man before killing him. The story gains its intensity by the manner in which it portrays how the narrator stalks his victim - as though he were a beast of prey yet, at the same time, elevated by human intelligence to a higher level of human endeavor, Poe's 'murderer' is created into a type of grotesque anomaly. Even though this is one of Poe's shortest stories, it is nevertheless a profound and, at times, ambiguous investigation of a man's paranoia.
