Q: Who is responsible for the murder of Duncan? The weird sisters? Macbeth? Lady Macbeth?
I feel as though Lady Macbeth is responsible for the murder of Duncan. Macbeth was a kind, loyal man before the murder occured. He was rewarded from King Duncan for his courage and successful battle, and promoted to Thane of Cawdor. Lady Macbeth is a major contributer to the death of Duncan as she influenced and pressured Macbeth to kill him. Lady Macbeth purposes the plan of killing Duncan and continues to carry it out. Macbeth begins to second guess the plan, and decides not to kill Duncan as he says "We will proceed no further in this business" (Shakespeare I, ii, 31). Shocked by his agruement, Lady Macbeth calls him a coward, insults his manliness and declares she would have killed her own baby "and dash'd the brains out" (I,ii, 58) than break a promise to not kill Duncan. Macbeth is then defeated and gives into her plan to prove his manliness. Lady Macbeth is also indirectly influenced by the weird sisters prophesies because without knowing Macbeth would become King she wouldn't have had the mindset to kill Duncan. Therefore, Lady Macbeth is responsible for the death of Duncan because she persuades and encourages Macbeth by insulting and demeaning him.
