Proctor assumes that since Marry is a member of the court her testimony that the Abigail has lied and the proceedings are false will change the course of the convictions. His goal is to stop the proceedings and free Elizabeth, his wife. Proctor, however, does not realize the power Abigail holds over the girls and the court. When Mary Warren accuses her in front of the court, Abigail becomes angry and pretends that Mary is sending her spirit out to harm her. Mary becomes frightened and is unable to stand up against Abigail. Out of fear, Mary soon joins in with Abigail and the girls and eventually turns on Proctor to save her own life.
Proctor's goal in bringing Mary Warren to court is to get the truth out, end the witchcraft madnes, and clear his wife, Elizabeth, of the accusations. He does not even care that his adultery may come out in the open, just as long as everyone knows the character of Abigail and can see that her accusations are false. Mary knows that Abigail and the other girls are faking their supposed attacks by witches. Mary is the one who made the poppet and gave it to Elizabeth as directed to set her up for a witchcraft charge. Unfortunately Mary is not strong enough for the task. She begins to tell her story at the court and the others begin to call her a witch. Then she recants of her story and begins to accuse Proctor of witchcraft.
