Macbeth¡¦s ambition changed his personality greatly. He used to be loyal to Duncan, the King of Scotland: ¡§The service and the loyalty I owe / In doing it pays itself.¡¨ (I, iv, 25-26) Also, he was well-known and respected for his bravery on war fields. However, the witches¡¦ prophecies made him ambitious. Macbeth betrayed the beloved King Duncan, who deeply trusted him, by making plans to kill Duncan: ¡§I am settled and bend up / Each corporal agent to this terrible feat.¡¨ (I, vii, 92-93) Ambitious had turned him from an honest man to a villain. It was the first step of Macbeth¡¦s fall.
Macbeth¡¦s ambition deteriorated his relationship with his friends. King Duncan and Macbeth used to be good friends. Nevertheless, Macbeth¡¦s ambition filled his mind and blinded him. He began to see Duncan as an obstacle on his way of being king, and he just wanted to get rid of him: ¡§Hear it not, Duncan, for it is a knell / That summons thee to heaven or to hell.¡¨ (II, I, 76-77) Banquo was Macbeth¡¦s old friend, who had fought with Macbeth in countless wars. Nonetheless, Macbeth was afraid that the witches¡¦ prophecy about Banquo, which indicated that Banquo¡¦s descendents would be kings, would come true. Thus, Macbeth saw Banquo and Fleance as enemies: ¡§So is [Banquo] mine [enemy], and in such bloody distance that every minute of his being thrusts / Against my near¡¦st of life.¡¨ (III, I, 132-134) Macbeth hired murderers to kill Banquo and Fleance. His ambition lost him two of his intimate friends,.
