Quotes from Macbeth who says and let the angel whom thou?

"And pity, like a naked newborn babe/ Striding the blast, or heaven's cherubins, hors'd/ Upon the sightless couriers of the air,/ Shall blow the horrid deed in every eye,/ That tears shall drown the wind. I have no spur/ To prick the sides of my intent, but only/ Vaulting ambition, which o'erleaps itself/ And falls on the other.'"-Macbeth
