What is the character of lady Macbeth in Macbeth?
Lady Macbeth is one of Shakespeare's most interesting female characters. Her personality and ambition rivals that of Shakespeare's male characters. She is fully aware of how her personality can be used to achieve her own goals. Lady Macbeth plots to kill Duncan and is able to bring Macbeth into her scheme.
She uses her femininity to manipulate people and push them into doing tasks that can be considered masculine. The act of murder is one of these male oriented acts. Women are thought to not possess the ambition and tendency toward such inclinations. They are gentler, if not weaker, gender so to have a woman with such lofty goals and determination to put her thoughts into action is noteworthy. It helps to explain why Shakespeare chose to create a character like Lady Macbeth.
However, at the end of Macbeth, she becomes a shell of her former self. She is weakened by guilt from her part in the murder of Duncan. She wanders about trying to remove the stigma of her sin. Lady Macbeth can not get the blood off of her hands. This weakened state she finds herself in is why she ultimately kills herself. Her guilt and pain is too great to endure any longer.
