How is Lady Macbeth opposite to duplicitous cunning and controlled?

I am writing an essay about comparing the presentation of Lady Macbeth in Act 1 and Act 5, scene 1. And i have written a paragraph about how she is represented as duplicitous cunning and controlled but I need a couple of quotations from Act 5 of how she is opposite to how she is represented as at the beginning. Any help would be appreciated.

1. Out, damned spot! out, I say!--One: two: why, then, 'tis time to do't.--Hell is murky!--Fie, my lord, fie! a soldier, and afeard? What need we fear who knows it, when none can call our power to account?--Yet who would have thought the old man to have had so much blood in him. The thane of Fife had a wife: where is she now?-- What, will these hands ne'er be clean?--No more o' that, my lord, no more o' that: you mar all with this starting. Here's the smell of the blood still: all the perfumes of Arabia will not sweeten this little hand. Oh, oh, oh! This is all said by Lady Macbeth after she goes insane.
