Meanwhile, the gullible Roderigo has abandoned all hope of Desdemona, but Iago urges him to kill Cassio and rekindle his hopes. Late that night, they attack Cassio in the street, but it is Cassio who wounds Roderigo. Iago rushes out and stabs Cassio in the leg. Othello, hearing Cassio's cries for help, believes that half of the revenge is completed and hastens to fulfil his undertaking.
Desdemona is in bed when Othello enters. He tells her to pray a last prayer as he has no wish to kill her soul. Realizing that he plans to murder her, Desdemona protests her innocence of any wrongdoing. Knowing that he doesn't believe her, she begs him to let her live just a little longer, but he smothers her with a pillow.
Emilia, Desdemona's servant and Iago's wife, upon discovering the ruse, raises the alarm and declares Iago a liar before Montano and Gratiano. She explains how Desdemona's handkerchief came into Cassio's possession, and when she refuses to be quiet, Iago stabs her. Cassio, wounded, confirms Emilia's story. A soldier to the last, Othello stands on his honor. Knowing that this is the end, he asks to be remembered as "one that loved not wisely but too well." Then he stabs himself and falls on the bed beside his wife, where he dies.
