To cause a diversion from all issues and mysterious feuds we continue the study of Macbeth or The Scottish Play:
The theme of the play, according to G.R Elliot is that a "wicked intention must in the end produce wicked action unless it is not merely revoked by the protagonist's better feelings, but entirely eradicated by his inmost will, aided by Divine grace." This is seen most clearly in Act V, Scene 1, where the Doctor says, "More needs she the divine than the physician." It also seen throughout the play in Macbeth's murderous plots.

Also rampant through the play is the idea of "Fair is foul, foul is fair." Basically, this means that appearances can be deceiving. What appears to be good can be bad, and this is seen in such things as the deceptive facade of Lady Macbeth and in the predictions of the witches.

The play as a variety of underlying motifs, such as the supernatural, the temptation of evil.

Shakespeare´s Macbeth THIRD WITCH: A drum, a drum! Macbeth doth come. ALL. The weird sisters, hand in hand, Posters of the sea and land, Thus do go about, about, Thrice to thine, and thrice to mine, And thrice again, to make up nine. Peace! The charm's wound up.

Yes, there are indeed three evil witches.. causing so much sad and worry.

...whereof, as saith Ecclesiastes, "It is our portion under the sun"
