LM is responsible for the tragic downfall of her husband.

I need proof supporting this statement. It is for a persuasive paragraph. Aside from the fact that she was the one who initially persuaded him to kill Duncan, how else is she responsible?

Not many ways else, to be honest, at least insofar as I can see. After the murder of Duncan and the feast that Banquo barely makes (cough cough), Lady Macbeth is mostly out of the picture in relation to her husband. You could make an argument that her madness drives her husband to tyranny, but the exclusivity of that factor is questionable.
