Othello

Her honor is an essence that’s not seen;
They have it very oft that have it not. (IV.i.)

Nature would not
invest herself in such shadowing passion without some
instruction. (IV.i.)

Dost thou hear, Iago?
I will be found most cunning in my patience,
But—dost thou hear?—most bloody. (IV.i.)

Ay, let her rot and perish and be damned tonight, for
she shall not live. No, my heart is turned to stone: I
strike it, and it hurst my hand. Oh, the world hath not
a sweeter creature. She might lie by an emperor’s side
and command him tasks. (IV.i.)

I will chop her into messes! Cuckold me? (IV.i.)
