Macbeth gives a last attempt at bravery by saying that he will die fighting.
In the time of Macbeth witches were not thought to be supernatural beings themselves, but supposedly gained their powers by selling their souls to Satan.
If Macbeth did not have any influence from the witches than he probably would not be thinking about killing Duncan to become King. They could predict the future, bring on night in daytime, cause fogs and tempests and kill animals.
The weird sisters set Macbeth's fate into motion. He knows he can never be defeated until the forest moves and he believes that he is secure.
At this point the witches have been a catalyst for the evil in Macbeth because this is partly due to the prophecies as they did not say anything about killing the king but only make Macbeth stir up the thoughts in his head.
He will only use his sword against Macbeth.
The scene in which Macbeth goes to the witches of his own accord is an important one because it sets the mood for his approach to the rest of the play. Consider the role of the witches and suggest how they can be made as successful for a modern audience as they would have been for a contemporary audience.
The witches portray many themes in Macbeth, such as the theme of fate, and the way that they are supposed to have the power of changing someone's fate, and the way they can control people using their power.
Whose actions led to Macbeth's demise? Shakespeare's Age-Old Question By writing the Macbeth witches as he did, Shakespeare is asking an age-old question: Are our lives already mapped out for us, or do we have a hand in what happens?
But with the witches help this idea was thrust to the front of his mind and he thinks that he should kill Duncan because the witches say that it is his destiny. Macbeth builds up an argument in his head to help him decide what to do using imagery, as he has strong opinions of right and wrong.
