Obsession is the state of being obsessed with someone or something. Crazy means you are mentally ill and crazy. In my opinion, obsession and madness correspond to completely different situations. Obsession does not necessarily mean insanity, as it depends on the situation. Edgar Allan Poe is known for his short stories and are told by reliable narrators, but "The Tell-Tale Heart", the anonymous narrator is crazy and suffers from mental illness and there are many reasons why he is crazy with evidence to prove it. . He claims he's not crazy but he's very nervous. Even though he tries to convince that he is very careful while murdering the old man. A reliable narrator would not be in a hurry to justify his act, but only to tell it simply and without embellishment. We can clearly see that the narrator is a man obsessed with the active senses, the narrator is not crazy, he is said to be extremely intelligent and to suffer from mental illness. A madman cannot think and argue like the narrator. So we can't say he's crazy or obsessed with murder, we know the narrator is unreliable just by reading the first sentence. The narrator's obsessions are: the old man's evil eye and the old man's heartbeat. The narrator is an example of an unreliable narrator because he tells the entire story himself and there is no objective narration to support his claims. Since this narrator cannot explain his actions without constantly explaining himself, he cannot be completely trusted. Poe says of the unreliable narrator: “It's true! - nervous - very, very terribly nervous, I had been and am; but why do you say I'm crazy? The illness had sharpened my senses, without destroying or dulling them. Above all, the sense of hearing was acute” (Poe 691). Obviously, the narrator is me... middle of paper ... In conclusion, the narrator was obsessive, and he denied his madness, and he claims that he was not crazy. At the end of the story, it's a mind game over a question of his own choosing that lets him down from a near-perfect murder. His unreliability comes directly from this first paragraph of the short story, when he swears about his clarity of mind. But little does he know that he starts to lose his mind when he talks to the cops and reveals the game on his own. He imagines the heart of the old man who gives the game under the ground as he becomes stronger. It is impossible that the heart could have beaten; he literally tore the body into pieces. This side can cause a person to do bad things that they would never normally think of doing. It's insane that he had to kill the old man just because he didn't like his pale blue eye and to ease his pain..
