Although Abigail does not work she the devil, she still is motivated by her own demons of jealousy. The Salem Witch Trials are a product of theocratic repression that spawned an ideology in which if something wasn’t good, it was automatically evil.

This cockiness was another reason she was so confident in her own jealousy of Elizabeth.
