in the stoy the crucible what motivates may to bing the poppet into the house

The poppet was supposed to be a gift from Mary but we sense the whole thing was devised by Abigail to bring down Elizabeth. The poppet demonstrates that Abigail Williams is more villainous than earlier indicated. In the first act she behaved solely out of self-interest. She was ready to do harm to others, but only to save herself. However, in this instance she purposely frames Elizabeth Proctor out of revenge, planting the poppet as a means to engineer Elizabeth's murder. This event even breaks the icy exterior of Elizabeth Proctor, who deems that Abigail must be "ripped out of the world."
