Macbeth's Fate

As I was trying to come up with an idea as to what to write for this blogpost, I couldn't help but wonder that if the witches never told Macbeth his fate, would he have become so obsessed with having it all play out? This thought then led me remember the Fates from Greek Mythology. Like the witches, the Fates were described as ugly hags, and were magical, you could say, deities who determined your fate. While they were not gods, they were powerful in the sense that even gods were powerless to stop them for their actions, such as ending one's life. Considering that even gods were unable to change their fate, it leads me to believe that, while Macbeth's path was not the cleanest one,  there was no way for him to go against his destiny.
