Macbeth (2006) (ATOM Study Guide)

I am in blood
Stepped in so far, that, should I wade no more,
Returning were as tedious as go o'er.

Those are the lines that spring to my mind whenever I think of Macbeth. For one thing, 'blood' is perhaps the motif which colours the whole play for me, and, for another, in the weary self-knowledge of that dreadful image speaks a man who is very far from being the 'butcher' Malcolm calls him at the end.
