What do Emilia's comments about men and jealousy in Scene IV of Othello say about her character?

In Act 4, Scene 3, Emilia demonstrates her disillusionment
with men and marriage as she speaks to Desdemona. The idealistic Desdemona cannot fathom
her husband's suspicion of her because she finds it difficult to believe that a woman
would be false to her husband. However, Emilia's experience with Iago--a husband who
belittles her in public and who has proved that his opinion of women's value is
abysmal--has jaded her. When Desdemona asks Emilia about women cheating or engendering
jealousy in their husbands, Emilia not only admits that she would cuckold her husband if
it would gain power for him, but she also tells Desdemona that it would be the man's
fault if the woman cheats. She explains that men's jealousy causes women to get revenge,
that women have lustful desires just as do men, and that men cheat on their wives which
justifies a woman's desire to cheat. Emilia's worldly perspective illustrates her
experience as a wife and serves as a foil to Desdemona's innocence and
purity.
