Betty Parris does not accuse people in The Crucible by Arthur Miller. Abigail Williams is the one who begins accusing people of witchcraft, and she is joined by other young women in the town. Betty Parris is Abigail's cousin, and she is one of the first people to be accused. However, Betty does not accuse anyone herself. She is merely used as a pawn by Abigail and the other girls to further their own agendas.
