Questions revolving act 1

So I have 5 questions that need to be answered and supported by evidence such as quotes or a refrence to a scene/ event

1. What is Macbeth like at the start of the play?

2. How does Macbeth read to the witches predictions and what does his reaction tell us about him?

3. Why does Macbeth belive the witches?

4. Why might Macbeth be reluctant to kill the king?

5. How does Lady Macbeth persuade Macbetch to kill Duncan?

These questions revolve around act 1 only
