The idea of power corrupts

My passage is from Act 1, Scene 7:

What beast was't, then,
That made you break this enterprise to me?
When you durst do it, then you were a man;
And, to be more than what you were, you would
Be so much more the man. Nor time nor place
Did then adhere, and yet you would make both:
They have made themselves, and that their fitness now
Does unmake you. I have given suck, and know
How tender 'tis to love the babe that milks me:
I would, while it was smiling in my face,
Have pluck'd my nipple from his boneless gums,
And dash'd the brains out, had I so sworn as you
Have done to this.

This passage connects with the essential question "How does power corrupt?"

I selected this passage because I feel that it really shows how for Lady Macbeth the idea of power totally corrupted her to want to kill the King without thinking twice. I think it is a powerful passage because she is trying to convince/guilt Macbeth into agreeing with the plan. This passage drew me in because it reminded me of peer pressure. Lady Macbeth has been corrupted by the thought of power so now she is trying to do anything to gain that power. But to gain power, she must convince Macbeth to kill the king, therefore, she uses peer pressure to do to so. I don't really think that it connects to me, but it connects to teenagers as a whole because of the whole peer pressure idea. I think it is very relevant to the play because this shows how all of the conflict in the play starts. It shows the start of Macbeth's need for power and how his is corrupted by power.
