"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 hurts my hand. Oh, the word hath not a sweeter creature! She might lie by an emperor's side and command him tasks." ( 117)

In this passage, Othello is extremely angry at his wife. He's telling Iago that he doesn't care for her anymore, that his 'heart is turned to stone'. He also mentions that she is going to die, and after this they begin plotting how he will kill her. This passage is important because it shows the extreme contrasts between love and jealousy. Othello would rather have his wife dead than be jealous.

Comment: This is an important passage, I agree. It's insane that Othello would go to such an extreme case due to his jealousy.
