According to Elizabeth, what is Abigail’s true objective in court?

Elizabeth is well aware of the interactions between
Abigail and her husband, but she could never have predicted what Abigail would do to get
her way.  Once Abigail learns how easy it is to accuse women in the village of
witchcraft, she points her finger towards Elizabeth.  Stabbed by Elizabeth's ghost,
Abigail is seen with a needle stuck into her stomach.  Elizabeth knows that she has not
sent her spirit out and certainly has not bewitched Abigail.  Outraged, Elizabeth
declares that Abigail means to kill her and dance on her grave.  Elizabeth realizes that
Abigail's ultimate plan is to charge and kill under the guise of witchcraft, and then
move in on her newly single husband, John Proctor.
