Mary's motive in giving the poppet to Elizabeth in The Crucible by Arthur Miller?

In Arthur Miller's The Crucible, Mary Warren gives Elizabeth Proctor a poppet as a gift to show her goodwill and to indicate her newfound independence and assertiveness as a member of the court. However, the poppet inadvertently becomes a symbol of betrayal, as Abigail Williams uses it to falsely accuse Elizabeth of witchcraft. Mary's gesture, initially intended to be innocent and supportive, ultimately contributes to the tragic consequences of the witch trials. This act reflects the themes of manipulation and the fragility of trust in the play.
