What can you infer about Lady Macbeth based on her soliloquy?

From the text, we can infer that Lady Macbeth is ambitious, centered, and strong willed. Her ruthlessness is also apparent in the fact she knows she may have to take drastic measures in order for her husband to kill Duncan.

According to the psychoanalysis theory, Lady Macbeth is the other part of King Macbeth so that Like good angel and evil angel Lady Macbeth tries to provoke Macbeth to kill Duncan.

From the soliloquies it is very clear that Lady had a sharp tongue and complex mind and knows how and why to provoke Macbeth but later in Sleep walking scene she has a guilt conscious mind and knows "what is done couldn't be undone".
