Whereas Banquo remained a good man, let the prophecies slide and only worried about trying to keep Macbeth from indulging himself into what the witches had said. Immediately following the witches first prophecy, Banquo feels nervous as to what Macbeth is thinking so he begins to try and keep Macbeth's mind on the good side, and as far away from the evil side of things. " And oftentimes, to win us to our harm, The instruments of darkness tell us truths, Win us with honest trifles, to betray's In deepest consequence. Cousins, a word, I pray you" (1.3. 123-127). As this scene continued, Banquo fought to keep Macbeth from dwelling on the witches prophecies. No matter Banquo's effort, Macbeth was slipping and crossing over from the good side to the dark side. Macbeth is the main character in this play, we see him change both socially, mentally and physically throughout. Previous to him entering the door of evil, he posed as a tough, masculine, heroic warrior, who was very well respected and a man who had a loving relationship with his wife; they were best friends. All around, Macbeth truly represented a "good man", fighting for his country in battle, and carrying the two titles; Thane of Cawdor and Thane of Glamis. During the play, we begin to see his dark side creeping out when he is considering killing King Duncan to fulfil the witch's prophecy of Macbeth becoming King. In Act 1, Scene 7 Macbeth's conscience speaks, of all good words, which leaves the audience still loving him and now hoping he will remain on the good side of the play. " He's here in double trust: First, as I am his kinsman and his subject, strong both against the deed; then as his host, who should against his murderer Shut the door, Not bear the knife myself" (1.7. 11-15). Through this scene, Macbeth faces the fact that there is no reason to kill the King other than his own ambition, which he realizes is an unreliable guide.
