The witches also known as the “weird sisters” are one of the most evil characters in Macbeth. In part, the mischief they cause comes from their supernatural powers, but mainly it is the result of their understanding of the weaknesses of their victims. They play upon Macbeth’s ambition like puppeteers. The witches’ beards, bizarre potions, and rhymed speech make them seem slightly strange and supernatural. Shakespeare has them speak in rhyming couplets throughout, which separates them from the other characters, who mostly speak in blank verse. “Double, double, toil and trouble, / Fire burn and cauldron bubble” The three witches are one of the most evil characters because they are the ones who tell Macbeth he will be the successor to King Duncan, which makes him commit murder so he will become King more quickly. “All hail Macbeth that shalt be King hereafter.”
Macbeth is a Scottish general and the thane of Glamis who is led to wicked thoughts by the prophecies of the three witches, especially after their prophecy that he will be become thane of Cawdor comes true. “The Thane of Cawdor lives. Why do you dress me in borrowed robes…but treasons, confessed and proved, have overthrown him.” Macbeth is a brave soldier and a powerful man. He is easily tempted into murder to fulfil his ambitions to the throne, and once he commits his first crime and is crowned King of Scotland, he embarks on further crimes with increasing ease. Macbeth is one of the most evil characters because he commits treason and murders many other people.
Lady Macbeth is one of Shakespeare’s most famous and frightening female characters. When we first see her, she is already plotting Duncan’s murder, and she is stronger, more ruthless, and more ambitious than her husband. She seems fully aware of this and knows that she will have to push Macbeth into committing murder. “Yet do I fear thy nature, It is too full o’th’milk of human kindness to catch the nearest way.” At one point, she wishes that she were not a woman so that she could do it herself. Lady Macbeth manipulates her husband with remarkable effectiveness, overriding all his objections; when he hesitates to murder, she repeatedly questions his manhood until he feels that he must commit murder to prove himself. Afterward, however, she begins to go insane. Towards the end of the play, she has been reduced to sleepwalking through the castle, desperately trying to wash away an invisible bloodstain. “Here’s the smell of blood still: all the perfumes of Arabia will not sweeten this little hand.” Once the guilt has set in, Lady Macbeth’s sensitivity becomes a weakness, and she is unable to cope. She kills herself, showing us that she is unable to cope with guilt of King Duncan’s murder hanging over her head. Lady Macbeth is one of the most evil characters because she is responsible for the making Macbeth kill King Duncan.
In Conclusion I believe all 3 of these characters are evil but Lady Macbeth is clearly the most evil character in the play because she is so desperate for royalty that she manipulates her husband into committing treason and many other murders.
