Othello slept with Iago’s wife. 

Desdemona was attracted to Othello for his grand history, and all the dangers he had escaped.

Iago is extremely chauvinistic (sexist) towards women.

While Desdemona was faithful to Othello until the end, with her final words she betrayed his trust by telling Emilia that he has smothered her.

System feedback mechanisms are used to:

According to Iago, what is the “immediate jewel of soul”?

When Iago tells Cassio that “Our general’s wife is now the general,” what is he implying? 

What is Lodovico shocked to see when he arrives on Cyprus?

Which aspect is not typically covered under system governance?

According to Desdemona, she cannot conceive of a situation in which she would ever be unfaithful to Othello.
