Isn't it ironic?

Dramatic irony can be defined as irony occurring when the implications of a situation are understood by the audience but not the characters of the play itself. Shakespeare used dramatic irony in Othello by allowing the audience to see the innocence of Desdemona and the deceitfulness of Iago. Why did Shakespeare use this approach to write Othello? Shakespeare wanted the audience to see Iago damage the marriage of Desdemona and Othello, but if the other characters knew of Iago's plan to sabotage the newlyweds, Iago's plans would be ruined. Shakespeare also used dramatic irony to allow the audience to feel sympathy for Desdemona when they see Iago “poison” Othello's mind with thoughts of Desdemona's unfaithfulness. Shakespeare did not want to portray Desdemona as a “whore” to which she is referred to many times by Iago and Othello towards the ending of the play. Shakespeare wanted the audience to see Desdemona as her true self, which was pure and innocent. Shakespeare needed to show the audience the deceitfulness of Iago in order to build his suspense throughout the play. Othello would not be the same if the audience did not know the true sides of Desdemona and Iago.
