To be a man is to stand up and do what you say your going to do and not consider the concequnces with out thinking about it.  Yes becuase she believes that macbeth is not a real man because the job would have been done by now and you  do not have to think about why should i do it? or jut sitting there and letting it go as planned and wait for something to happen. i believe lady macbeth is more manly because she planned how the process is suppose to happen.
