Tell-Tale Heart

This story in particular was very crazy, because how come you are going to kill somebody and stay just calm as if nothing happened. Definetly, I can characterize the narrator in Poe's story by being an evil man. He must have psycological problem because it is impossible that you can commit such a crime and later you act as if nothing had happened. He was insane by the fact he planned everything and give details of how he was going to kill the old man. A good example of showing that he is mentally ill , is when he was trying to convince the reader that he wasn't mad but sane.At the end of the story, when he finally killed the old man, he still heard the old man's heart beat. Later, he confess that he killed him.
