Read the passage from "The Tell-Tale Heart.” (WILL GIVE BRAINLIEST)

I think it was his eye! yes, it was this! He had the eye of a vulture–a pale blue eye, with a film over it. Whenever it fell upon me, my blood ran cold; and so by degrees–very gradually–I made up my mind to take the life of the old man, and thus rid myself of the eye forever. Now this is the point. You fancy me mad. Madmen know nothing. But you should have seen me. You should have seen how wisely I proceeded—with what caution—with what foresight—with what dissimulation I went to work! I was never kinder to the old man than during the whole week before I killed him.
