Othello

Othello

That Cassio loves her, I do well believe ’t.
That she loves him, ’tis apt and of great credit.
The Moor, howbeit that I endure him not,
Is of a constant, loving, noble nature,
And I dare think he’ll prove to Desdemona
A most dear husband. Now, I do love her too,
Not out of absolute lust—though peradventure
I stand accountant for as great a sin—
But partly led to diet my revenge,
For that I do suspect the lusty Moor
Hath leaped into my seat. The thought whereof
Doth, like a poisonous mineral, gnaw my inwards,
And nothing can or shall content my soul
Till I am evened with him, wife for wife.
Or, failing so, yet that I put the Moor
At least into a jealousy so strong
That judgment cannot cure. Which thing to do,
If this poor trash of Venice, whom I trace
For his quick hunting, stand the putting on,
I’ll have our Michael Cassio on the hip,
Abuse him to the Moor in the right garb
(For I fear Cassio with my night-cape too)
Make the Moor thank me, love me, and reward me
For making him egregiously an ass
And practicing upon his peace and quiet
Even to madness. 'Tis here, but yet confused.
Knavery’s plain face is never seen till used.

This soliloquy is the foundation of the plot and the tragedy of this story. It revolves around the concept of revenge. Iago hatred is derived from Othello who passed the position of lieutenant to Michael Cassio, who, in his eyes seem like an unexperienced young man.  
This particular soliloquy foreshadows the great deception Iago will engineer. ‘for that I do supposed the lusty Moor hath leapt into my seat...’ during the Elizabethan period black men is said to have an animal...
