What is lady macduff like?

She was a very kind lady with a loving heart who cared after Macbeth. Why, she even agreed to go into Duncan's bedroom with the bloody knives and smear blood all over Duncan's servants, so that they would be blamed for the murder and hanged for it. Wasn't that a nice thing to do? She is shown praying for the success of her enterprise, too. What a pious woman! She says, "Come to my woman's breasts and take my milk for gall, you murdering ministers." And she is so kind and nice that when Macbeth had decided not to murder Duncan after all she calls him a coward and nags at him until he agrees to do the murder. And when Macbeth is nearly scared out of his mind by the appearance of his friend's ghost, she cheers him up with these loving Words: "Shame itself! Why do you make such faces? When all's done, you look but on a stool."

Actually she is ambitious, cowardly, uncaring and shallow, and most dangerous of all, has no conception of the long-term consequences of her acts.
