Act IV of Macbeth

In the beginning of Act IV, Macbeth meets with the witches once more while they are making a potion to get an update on his future. This time, he speaks with more arrogance, calling the witches "hags" and other curses. The king is exposed to three aparrations that state three different dangers. He will not be dethroned until the Birnam Woods move towards the castle of Dunsinane, a man born of woman can not hurt him, and to fear Macduff. Macbeth believes he is safe because no man is not born of a woman, and woods cannot move. But he hears about Macduff and becomes cautious about him. After recieving news from Lennox that Macduff has traveled to England in search for Malcolm, Macbeth is enraged and decides to take it out on his family. He hires murderers again to do his dirty work and go and kill his wife and children. It is clear that Macbeth does not think twice or contemplate his decisions anymore because he wasted no time in trying to get at Macduff for 'betraying' him. While this is happening Macduff finds Malcom in England. He is persuading Malcolm to come back, but Malcolm feels he is being set up, so he tests Macduff's loyalty-- claiming he would be a much worse king than Macbeth. Shortly after, Macduff tells Malcolm they must stand up and fight for their homeland back, so they plan to build an army of rebels and attack Macbeth. Ross the messenger of the story, informs Macduff that his family has been murdered and Macduff loses it. Macbeth has clearly become a cold blooded monster who is only concerned about his own safety and power which reveals the irony of what he was at the beginning of the story.
