Abstract: Perhaps there is no subject more exciting than sexual Jealousy rising to the pitch of passion; and there can hardly be any spectacle at once so engrossing and so painfull as that of a great nature suffering the forment of this passion. William Shakespeare knew it as being a master of reading and presenting human natures. So, he projects a character absolutely evil unified with supreme intellectually power. Driven by an over powering lust for evil rivaled only by Satan, Iago is titled as worst Shakespearian Villain hands-down.
