I need help with finding a good title for my essay...My essay is about how supernatural events drive Macbeth to rely on his ambition and neglect...

As you have said that your subject matter is all about the
influence of the supernatural on Macbeth which distracts him through instigation, I
would suggest you two titles. These are as follows:

1.
Evaluation of the role the supernatural plays in
Macbeth

or,

2.
How far the supernatural is responsible for the tragic consequence in
Macbeth?

You can, now,
choose either. Just make sure the thesis statement does contain the key phrases of your
title.

Good luck!
