Compare the Reactions of Macbeth and Banquo to the Witches’ Prophecies

At scene three, Macbeth and Banquo both are shocked by the appearance of the witches. They greet Macbeth and inform him that he will become Thane of Cawdor and also King of Scotland.

Banquo still could not believe the witches that ‘tis strange-and often, to win us to our harm’ and is worried about Macbeth. Eventually, he...
