Does Macbeth really have control of his fate?

Macbeth has always had control of his own fate, his hunger for power soon turned against him. The weird sisters put thoughts and predictions into his head, ones that made him crazy. He felt insecure and felt that he HAD to kill King Duncan to become King. In some way, the weird sisters were part of this 'fate'. But he created his own fate by letting his own greed for power rule his decisions and actions.
