English macbeth

Think about the kind of things she does, e.g. persuading Macbeth to kill Duncan. What does that tell you about her? She's manipulative and persuasive. She selects the correct verbal tools that she knows will further push Macbeth to do what she feels needs to be done. She tries to undermine and question Macbeth's masculinity; she knows that by doing this, he'll want to prove himself, that he's strong, and capable of overcoming any fears to express his masculinity.

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
