This personage is known as Iago the honest somewhat contradictory one because Iago is the cause of all the problems in the play. The subaltern of Othello and is a very intelligent personage and he knows to manipulate the people in such a way that he can obtain the confidence of his “victims” Othello and Rodrigo. Iago causes lights up in the person honest and good friend before Othello but in the fund is not this. Iago causes jealousy and hatred in Othello toward Desdemona. Iago is one of most sophisticated villain in Shakespeare play. Iago reveals a great capacity to dissemble to all the people around him. In my opinion all this badness and very villainous of Iago is on account of the jealousy senses toward the love that has Othello feels to its wife Desdemona. This personage has many negative feelings wrapped as is it the envy principally, the hatred, racism and many other that do that the audience can realize its wickedness since early beginnings of the play when Rodrigo is influenced for Iago to try to conquer Desdemona. Then begin the conflict to can be the governor. Something that impresses me a lot because of all these tragedies occurred in the play in anyone is seen affected the personage of Iago because in the end he continues alive and although with his dead wife but by hand of himself. This plays is a tragic actuation but have many teachings to the audience learning.
