In Shakespeare's Macbeth, there is a question as to whether or not Macbeth is driven by fate or free will. The three weird sisters approach Macbeth with prophecies that will all come true in the end. It would appear that Macbeth is just following destiny at first. However, Macbeth always had a choice throughout the play to choose his own fate. Macbeth journeyed to his murderous doom through his own free choice. In Act I, the three witches visit Macbeth and Banquo on the heath. The witches make three predictions; Macbeth will be the Thane of Cawdor, he will be...
lived on account of the prophecies, not the reverse.

Macbeth's downward spiral of events was created through his own free will. The witches did foretell his future but they never directly controlled his actions. The sisters did not cast a spell to make Macbeth go crazy. He was engulfed in his lust for power and his battle with his conscience. This led to his insomnia and ultimate downfall. In the end his false sense of security created the atmosphere for the battle in which he was to be killed in. The witches influenced Macbeth's tragedy but he condemned himself.
