Macbeth was written and performed for King James. Shakespeare wanted to please the king, so he wrote a fairly short play (James liked short plays). King James himself had written a book on witches and how to detect them. For this, Shakespeare decided to add a supernatural twist to his play, as to please the king. Basically the King wrote a book about witches so Shakespeare thought putting witches in his play would please the king. Source: http://home.flash.net/~manniac/macb.htm
The witches in Macbeth refer to themselves as the "weird sisters."
MacBeth meets the three witches with lady MacBeth
Macbeth.
The witches only gave Macbeth prophecies. It was his decision to do so after Lady Macbeth persuaded him. Although the witches' intentions was probably to cause this murder, the witches did not make Macbeth muder Duncan.
Macbeth did not like what the witches had told him.
No, the witches are proclaiming and predicting that Macbeth will be king and they are praising Macbeth.
Lady Macbeth echoes the words of the witches when she says "All hail, Macbeth, that shalt be king hereafter!". This echoes the witches' prophecy that Macbeth will become king.
Macbeth does.
Banquo and Macbeth. And the other witches, of course.
I think that Macbeth was at first not as "worried" about the witches and their curses as then on in the play he finds out that every thing that the witches has been tellin him are true.
Macbeth did not like what the witches had told him.
the cursed of macbeth was that she will curse witches
