I think that Shakespeare has shown Macbeth as a over the top caricature who is always being extravagant even when he is being sad or scared. I think this is done by making Shakespeare reference religion, mostly Christianity, and have Macbeth question or challenge God.
In the play Macbeth says “both worlds suffer” this, I think refers to heaven and hell. This shows that Macbeth believes that his actions, multiple counts of murder, may shake both the place of good and the place of evil. In the times of Shakespeare religion was very strong and if a person was referring to the place of the Lord and place Devil in one word is a very symbolic thing to say as it could show that Macbeth’s good side and his evil side are now almost identical.
