Paranoia

Are Macbeth’s paranoia due to his own weakness or a consequence of what he did?

             Macbeth's paranoia could be due to both his weakness and the consequence to what he did. I believe so because he could be weak from knowing what he did. Also, since everything started with the witches, it could be them that is showing Macbeth that something is going to happen to him after everything is done. Since Baquo was his closest friend, he might also feel guilty that he killed him only for power. Basically, it could have happen because of three reasons. It could happen because Macbeth feels guilty for killing his best friend or he believes that it is too much to take with all these murders or it could also be the witches that are trying to play a trick on him. But when I think of it, it could of been all of the above.
