Act 1 Scene 5,According to Lady Macbeth's prayer to the evil spirits,what character traits must she possess if she helps Macbeth gain the crown?Has...

First she calls upon them to unsex her.  As a women, she
feels vulnerable and although she may want to kill the king and thus make her husband
the new king, she doesn't feel that she is strong
enough.

She asks them to empty her of all tender emotions
and fill her up instead with direst cruelty.  She asks them to shield her against
feeling remorse.

She asks them the keep her focused on her
"fell purpose" and let nothing get in the way.  Her fell purpose, of course, is the
death of Duncan.

Instead of the nurturing milk of a mother,
she asks that they fill her breast with poison.

In other
words, she asks them to give her the strength she feels that she needs to push her
husband into killing the king and helping, if necessary.   She knows that as a women,
her feminine sensibilities would interfere.  She feels that only the forces of evil can
help her.

Reality is something else entirely as she later
learns.
