This desperate act of self-preservation soon becomes Abigail's avenue of power. Abigail represents the repressed desires — sexual and material — that all of the Puritans possess.
The difference is that Abigail does not suppress her desires.
Her strategy includes establishing her credibility with the court and then eliminating Elizabeth.
The achievement of her plot requires cold calculation, and so Abigail carefully selects the individuals that she accuses in order to increase her credibility.
This vicious antagonist will stop at nothing to attain her demented goals.
Although, in the end, Abigail’s persuasive lies do not get her what she really wants, her actions throughout the play influence many events and make her the most compelling character of The Crucible.
Her decision to wait until the court sees her as irrefutable before she accuses Elizabeth reveals her determination and obsession with Proctor.
Abigail thinks nothing of the fact that she condemns innocent people to die; those people merely serve as necessary instruments for her use in the fulfillment of her plan.
Abigail Williams is the vehicle that drives the play.
She bears most of the responsibility for the girls meeting with Tituba in the woods, and once Parris discovers them, she attempts to conceal her behavior because it will reveal her affair with Proctor if she confesses to casting a spell on Elizabeth Proctor.
