Who Is To Blame In Shakespeare's Macbeth?

Who is responsible for Macbeth’s downfall, the witches, or Macbeth? Who is responsible for the scorpions in Macbeth’s mind, the savage killing of several people in cold blood, the conception near the end of the play that Macbeth grasps of nihilism, and Macbeth getting so shielded in the prophecies that he can barely see straight? Is it Macbeth... or the witches? The play by William Shakespeare, Macbeth, has many motifs and famous quotes. However, it raises a lot of questions. One of which is the question mentioned earlier, who is responsible for what happened? Who’s fault is it that Macbeth is so mad he says, “Oh, full of scorpions is my mind, dear wife!” (3.2.38).

But hush, no more.” (3.1.9-10). This means that Banquo will not act upon what the witches are telling him. What the witches are telling Macbeth would also never be coming true if he hadn’t acted upon it. As Banquo puts it in the play, “The instruments of darkness tell us truths,/Win us with honest trifles, to betray ’s/In deepest consequence.” (1.3.126-128). To reinforce what Banquo says, Macbeth already knows that he is thane of Glamis. There is a battle going on, and the thane of Cawdor died, but Macbeth has yet to hear wind about it. The witches could have knowledge about this, and just told him what he wants to hear about being king
