Free will vs fate is one of the biggest concerns of Shakespeare's plays
Explanation:
Shakespeare's heroes are often found compromised in ways that one would wonder if they are really in control of their lives as a fabric of witches, ghosts and soothsayers always surround the actions they make.
In Macbeth, the witches tell Macbeth that he will be king even before he starts conspiring and by extension this helps him think that it is his destiny. At the same time, it induces guilt.
