"Now, whether he kill Cassio, Or Cassio him, or each do kill the other; Every way makes my gain. Live Roderigo, He calls me to a restitution large Of gold and jewels that I bobbed from him As gifts to Desdemona. It must not be. If Cassio do remain, He hath a daily beauty in his life That makes me ugly."
"That thrust had been mine enemy indeed But that my coat is better than thou know'st I will make proof of thine"
"O, I am Slain!"
"Thats one of them"
"O damned Iago! O inhuman dog!
O murd'rous slave! O villain!
Iago is alone and explaining that if Roderigo lives he will want him to give the jewels he gave him to Desdemona and if Cassio lives then eveyone will see Iago as evil. So its better if both die.
"O, who hath done this deed?"
"Out, and alas, that was my lady's voice! Help! Help ho! Help! o lady, speak again! Sweet Desdemona, O sweet mistress, speak!"
"Nobody. I myself. Farewell. Commend me to my kind lord. O, farewell"
Roderigo tries to stab Cassio but he misses and Cassio stabs him. Iago comes back and stabs Cassio in the leg then leaves.
"By heaven, I do not, I do not, gentlemen! O murd'rous coxcomb, what should such a fool Do with so good a wife?
"Are there no stones in heaven But what serves for the thunder?- Precious villain!"
"The woman falls! O, lay me by my mistress' side"
"Cassio points out Roderigo saying he stabbed him. Iago acts like he doesn't know him and stabs him acting like the hero"
"I took by th' throat the circumcised dog, And smote him, thus"
"O bloody period!"
"Emilia finds out Desdemona is dead but doesn't know who killed her. Desdemona says she killed herself even though it was Othello."
Emilia exposes Iago saying that she took the handkerchief and that Cassio never had it. Iago got mad and stabbed her and ran away.
Othello can't deal with killing Desdemona because he now knows she was innocent so he decides to kill himself
