In a play that is abundant in evil occurrences, Lady Macbeth is the overriding source of evil in the first act. Lady Macbeth persuades Macbeth to kill Duncan, despite Macbeth listing reasons against the murder. When Macbeth is alone, we discover that he is a loyal thane to Duncan, not a murdering savage. When Duncan is in his house at Inverness, Macbeth comes to a decision not to kill Duncan. Lady Macbeth convinces Macbeth, who decided strongly against murdering Duncan, to go ahead with their plan to murder Duncan. Lady Macbeth is very successful at persuading him to do things that he knows are wrong. Macbeth is not an evil person, but when he is allowed to be influenced by Lady Macbeth, he is vulnerable to committing deeds he knows are wrong. After Macbeth writes home telling of his murderous plans, Lady Macbeth begins talking to evil spirits. Because women often lack the ruthlessness to kill someone, Lady Macbeth asks the spirits to make her male. One of the most vivid descriptions of Lady Macbeth's wickedness is directly after Macbeth announces to her he does not want to kill Duncan.This speech epitomizes Lady Macbeth's evilness. She is ruthless, and her evil accounts for the murders that occur throughout the play Macbeth.
Lady Macbeth is far more savage and ambitious than her husband, yet she convinces Macbeth to commit the murders that will make them king and queen. Macbeth is without his wife's cruel and uncompassionate attitude towards life. Lady Macbeth is aware that her husband is genuinely a gentle person. However, she is able to manipulate Macbeth into committing evil deeds in order to achieve her desires. Lady Macbeth fears that Macbeth lacks enough courage and killer instinct to murder Duncan. Lady Macbeth might be a more vicious individual, but she is more afraid than Macbeth about killing Duncan. She never mentions herself committing the murder, and she always insists upon Macbeth.
