The Tell Tale Heart

Is the man crazy, or not? In an instant I dragged him to the floor, and pulled the heavy bed over him. I then smiled gaily, to find the deed so far done. But, for many minutes, the heart beat on with a muffled sound. This, however, did not vex me; it would not be heard through the wall. At length it ceased. The old man was dead. Wow this guy is nuts. He killed the man for what reason? An eye. He definitely is crazy because no one in their right mind would ever think about that.
One reason that this man is crazy, is because of the way that every night he would hide in the mans bedroom every night for hours. I don't know if anyone in their right mind would ever think about doing that. He did this just because of the old mans eye. Couldn’t he just leave his job and the man and go somewhere else? If he would have done that, then he wouldn't have had to kill someone, and wouldn't get caught by the police. Also at the end of the story when the police are in the house, and he starts hearing the ringing in his head. He thinks that it is the old mans heart, but that's not possible at all. He is crazy if that's what he thinks it was.
Although it seems that this guy is completely insane, there are some reasons that make it seem like he is a perfectly normal person in every aspect. For example could a mad person think of this plan? Probably not. It was not a perfect plan, seeing as he got arrested, but it almost worked. A crazy person could not possibly think of that.
While it seems that this guy could be both normal or insane, I think that he is absolutely crazy. A normal person would not deliberately kill someone just because they didn't like the eye of that man. Also, doing the same thing every night for hours seems just weird. This story was almost scary by the way that he planned out what he was going to do. The person in this short story was definitely insane because of how he planned and killed the man.
