Iago has convinced Othello that his wife, Desdemona is cheating on Othello with Cassio. This has left Othello contemplating over Desdemona's faithfulness. At first Othello did not believe a word Iago said about Desdemona, but as soon as there was the slightest amount of evidence. Othello started believing and eating all the words that Iago said. During Othello's soliloquy, he doesn't appear to be the same self-confident General he was formerly portrayed as. Instead, indecision over his wife's infidelity has caused him to explore his flaws as a human being. Showing signs of appearance versus reality.
This fellow's of exceeding honesty,
And knows all qualities, with a learned spirit,
Of human dealings. If I do prove her haggard,
Though that her jesses were my dear heart-strings,
I'd whistle her off, and let her down the wind
To prey at fortune. Haply for I am black
And have not those soft parts of conversation
That chamberers have; or for I am declined
Into the vale of years-yet that's not much-
She's gone: I am abused, and my relief
Must be to loathe her.
O curse of marriage,
That we can call these delicate creatures ours
And not their appetites! I had rather be a toad
And live upon the vapour of a dungeon
Than keep a corner in the thing I love
For others' uses. Yet 'tis the plague of great ones;
Prerogatived are they less than the base.
'Tis destiny unshunnable, like death:
Even this forked plague is fated to us
When we do quicken. Desdemona comes!
If she be false, O then heaven mocks itself!
I'll not believe't.
The conniving Iago has unquestionably caused Othello to be suspicious of Desdemona's fidelity. Othello, like every one of the other characters, is duped...
