Othello Act 4 Scene 1 Key Passage Analysis

The passage that I decided to analyze was:
"OTHELLO:
She is protectress of her honor too.
May she give that?
IAGO:
Her honor is an essence that's not seen;
They have it very oft that have it not.
But, for the handkerchief -
OTHELLO:
By heaven, I would most gladly have forgot it.
Thou said'st - Oh, it comes o'er my memory
As doth the raven o'er the infectious house,
Boding to all - he had my handkerchief.
IAGO:
Ay, what of that?
OTHELLO:
That's not so good now" (Othello 4.1 14-24).

Analysis:

Here, Othello is talking with Iago. Othello is saying that with the handerkerchief, Desdemona gave away her honor and loyalty to him. Othello is using a metaphor for the fact that he feels horrible and angry and like the fact that Iago brought it up is like the last straw. Othello is also saying that he wishes he could forget it. I think that this will prove to be important later on, because it show's how Othello is changing both emotionally and mentally. He is starting to let his jealousy get the best of him.
