Identify the similarities and differences between Abigail Williams and Macbeth.

Abigail Williams is a teenage girl living in Salem, Massachusetts during the late 1600s, while Macbeth is an older Scottish soldier living during the Middle Ages who gets promoted to Thane of Cawdor and eventually becomes king. Abigail is an oppressed girl, who is initially overlooked by the members of Salem's community because of her age and gender. In contrast, Macbeth is revered by King Duncan and the Scottish lords for his exploits on the battlefield. Abigail's accusations are driven by revenge as she attempts to get rid of Elizabeth in order to have John Proctor to herself. Macbeth's violent nature is a result of his ambition and hopes to secure his authority.
Despite their many differences, Abigail and Macbeth share several similarities. Both characters are portrayed as selfish, callous, and violent. Abigail doesn't think twice about ruining the lives of innocent citizens, and Macbeth murders several characters throughout the play in order to attain and secure his title as king. Both characters participate in the dark arts and are involved in sorcery of some sort. Abigail drinks blood in hopes of cursing Elizabeth, and Macbeth consults the three witches about his future. Also, both characters' actions turn their communities into hostile, dangerous environments.
