Macbeth’s second visit to the witches and the predictions he hears make him more cautious and thoughtful. more bold and cruel. more afraid of lady macbeth. more willing to kill duncan. of what duality does lady macduff become aware before she is murdered? that doing harm is “often laudable,” but doing good may be “the surest way to anger macbeth” that doing harm is “often laudable,” but doing good may be “more laudable” that doing harm is “often laudable,” but doing good may,

The predictions make him more bold and cruel, as Hecate is trying to make him overconfident. He becomes especially bold when the final apparition says that 
'Macbeth shall never vanquish'd be until
Great Birnam wood to high Dunsinane hill
Shall come against him.'

Lady Macduff becomes aware that doing harm is often laudable, and doing good can lead to 'dangerous folly,' meaning that sometimes bad deeds are done by bad people and go unpunished, regardless of our intentions.
