Iago Is an Eeeeeeevil Man

So, I have come to the conclusion that Iago has to be one of the most villainous characters that I have ever read about. He is a horrible person who justifies his actions by saying that because he is witty, it makes it all okay. From reading the play, I understand him to think that just because he is a "smart" person, it is okay to take advantage of those, according to him, to fall for his act. Also, I understand that Iago is angry because he was not promoted, and somebody with no experience was promoted ahead of him, but most people would get over it or discuss the act with their superiors. Iago, instead, decided to act on his anger and jealousy to dispose Cassio of his position and ruin his reputation. However, even further, Iago decided to drive it home by turning Othello against Cassio and his wife, Desdemona. Ultimately, Iago's plan ends in the death of Othello and Desdemona. Therefore, I think I have enough reason to conclude that Iago is an awful man who succumbed to the pressures of anger and jealousy, but did not stop until his lack of promotion was fully "avenged" in his mind with the death of Othello.
