who said what's done is done in macbeth
What's done is done One of the first-recorded uses of this phrase was by the character Lady Macbeth in Act 3, Scene 2 of the tragedy play Macbeth (early 17th century), by the English playwright William Shakespeare, who said: "Things without all remedy Should be without regard: what's done, is done"[2] and "Give me your hand. What's done cannot be undone. – To bed, to bed, to bed!"[3]
Macduff (Macbeth) After Macbeth slays the young Siward, Macduff charges into the main castle and confronts Macbeth. Although Macbeth believes that he cannot be killed by any man born of a woman, he soon learns that Macduff was "from his mother's womb / Untimely ripped" (5.10.15–16). The two fight, and Macduff slays Macbeth offstage. Macduff ultimately presents Macbeth's head to Malcolm, hailing him as king and calling on the other thanes to declare their allegiance with him (5.11.20–25).
