This sounds so animal somehow – like Hamlet is a lion dragging his kill to his lair. There’s something about calling Polonius “the body” and the action of “drawing apart” that has that effect. I know drawing apart means removing but it SOUNDS like a combination of drawing and quartering and ripping apart. It isn’t delicate language.
Maybe this is why the Queens adds the lie about Hamlet weeping over his deed – because she has gone too far in describing his kill.
