This play is written in a very clever fashion which leaves a lot of different factors undecided. This means that there are many different viewpoints which one could take on whether or not Lady Macbeth was responsible for the murder of King Duncan. There is a lot of evidence suggesting that she either was or was not responsible. So it is necessary that I take all of the different points into consideration.
We are given the impression that Lady Macbeth is a powerful woman who's sex appeal gives her influential properties over a lot of her husbands decisions. She is also a woman of great ambition and with the idea of her husband becoming king being presented she will do everything in her power to make him bring that about.
"Thou"dst have, great Glamis, That witch cries, "Thus thou must do if thou have it"; And that which rather thou dost fear to do, Than wishest should be undone.".
At the beginning of the play there is a scene which has Macbeth and Banquo returning from a victorious battle. They are riding on horseback, when they spot three witches. The witches are frail, old hags with beards and withered limbs. Upon questioning the first witch replies:.
"All hail, Macbeth! Hail to thee, thane of Glamis!".
Then the second witch continues:.
"All hail, Macbeth! Hail to thee, thane of Cawdor!".
Then the third and final witch makes her reply:.
"All hail, Macbeth! That shalt be King hereafter.".
(This event have been more potent in Shakespearian times because most of the audience in the theatre would have believed in witches. Unfortunately people have become more and more sceptical of legends and myths, which eventually led to the belief of witches and the such to die out.) .
Macbeth was utterly astonished at these events for many reasons. First he could hardly believe his eyes when he sees three witches before him and somehow they knew that he was thane of Glamis but then on top of that they prophesised that he would first become thane of Cawdor and then King of Scotland.
