The Witches.......

I think the witches are important to the play because they start the play of. They tell Macbeth and Banquo their furtues which sets the play into motion. I think this is important because otherwise if we hadn't heard the prediction and then Macbeth and Lady Macbeth killed the king anyway we wouldn;t feel any sort of sorrow for them at all, where as we can half and half sympathise with them for killing him and then the others. But it also raises the important question, which is " If the witches had never told Macbeth that he would be king, would he of killed the king????" it makes you question Macbeths motives, because Banquo hasn't forced his sons into the king chair he is waiting paitently for it too happen. It makes you question whether you think Macbeth should of left it and fallen into the king's chair by chance or by his own forceful nature.
When "Hecat" then shouts at the witches for telling Macbeth she says "hath been but for a wayward son, spitrful and wrathful, who, as others do, loves for his own ends, not for you" which makes you think that he probably would of done it anyway because he is a spiteful person who only wants to do things for his own self.
this is why i think the witches are important becasue they raise lots of questions for people to think about Macbeth.
