What arguments does Emilia make about the nature of revenge and infidelity (84-101)?

Emilia pronounces what seems like a theme of the play, up until this point; "let husbands know, their wives have sense like them Šthey see, and smell, and have their palates both for sweet and sour, just as their husbands have" (IV.iii.96-99). Indeed, this is one of the reasons why Othello is so angry with Desdemona; the thought that she could have desire in her, just as he does, bewilders and angers him. That she could have opinions and ideas independent of his own, especially about Cassio and his rightful place, also upset him.
