What is Betty Parris' motivation in The Crucible?

In "The Crucible," Betty Parris' primary motivation revolves around seeking attention and avoiding responsibility. As the daughter of Reverend Parris, her behavior directly reflects both her fear of the repercussions from her father's authority and the societal expectations placed upon her. Her initial fainting and subsequent fits can be seen as a way to divert attention away from her potential culpability in dancing in the forest, which is viewed as taboo.

By claiming illness and later participating in the accusations against others, she garners significant attention, both from her father and the larger community, who rush to her side, anxious to protect her. This attention ultimately provides her an escape from the consequences of her actions, as shifting blame onto others eases her own burden of guilt and fear. Thus, her motivations are rooted in self-preservation through the manipulation of her circumstances, rather than any desire for revenge or material gains.
