Abigail is also motivated by her desire for power. She wants to be the most powerful person in Salem, and she believes that accusing others of witchcraft will help her to achieve this goal. By making herself the center of attention, she can control the course of the trials and use them to her own advantage.
Finally, Abigail is motivated by her hatred of John Proctor. She wants to destroy him because he has rejected her, and she believes that accusing him of witchcraft is the best way to do this. She knows that if she can get John to confess, then he will be hanged and she will be free to marry his wife, Elizabeth.
