Shakespeare presents her as "crazy" with the blood on her hands. After she kills Duncan, she hallucinates.Lady Macbeth makes fun of Macbeth for not having the courage to kill Duncan – but when it comes to it, she can't kill him herself, and Macbeth has to do it. ... She starts sleep-walking and talking about Duncan's murder in her sleep. In the end, she kills herself.
Shakespeare definitely doesn't preset her as the "ideal" woman. We can see Macbeth listens to LMB even though it should be the other way. She is more cunning than Macbeth
So it's clear that she's controlling, manipulative, and with that comes ambition. She has high hopes for their future, and she's willing to do whatever it takes to get there. She exhibits many masculine features herself, and in some ways, she wants the spirits to "unsex' her, so perhaps she feels her being a woman holds her back, hence she attempts to persuade Macbeth to complete the murder. She's the brains, the cunning mind behind it, he's just the weapon.
She's cruel, powerful, and conniving. Have a Google and you'll come across a lot of resources and quotes that back up these points. This is just a very brief overview and summary of her, more detail is needed of course
