1. Accusations of Witchcraft: Abigail initiates the play's conflict by accusing innocent individuals of witchcraft. Specifically, she accuses Tituba, a slave in the household of Reverend Parris, of practicing dark magic. This accusation sets the stage for further false allegations and the spread of paranoia within the community.
2. Manipulation of Others: Abigail uses her charm, charisma, and cunning to manipulate those around her, particularly the young women in the town. She convinces the girls to join her in performing a strange dance in the forest, which is viewed as a satanic ritual. By leading them astray, she gains control over their behavior and thoughts.
3. Feigning Affliction: Abigail pretends to be afflicted by an unknown supernatural force. She displays strange fits, screaming, and contorting her body, convincing the community that she is bewitched. This pretense fuels the hysteria and fear among the townspeople.
4. Power Dynamics: Abigail recognizes that accusing others of witchcraft gives her a newfound sense of power and authority. By wielding these accusations, she can influence the town's decisions, influence the outcome of personal conflicts, and even shape the course of people's lives.
5. Rivalry and Desire: Abigail's desire for John Proctor, a married man, drives her actions and fuels her determination to eliminate anyone who stands in her way, including John's wife, Elizabeth Proctor. She uses the accusations of witchcraft as a means of getting rid of her rivals and securing her desired relationship.
Through her actions and motives, Abigail Williams sets in motion a series of events that spiral out of control, leading to the tragic consequences depicted in "The Crucible."
