Question

Mary Warren might be seen as the foil for Abigail. Explain how she is used to bring out Abigail’s traits

Answer 1

Abigail seems to feed on Mary warren's insecurity and fear.
The more Abigail asserts herself, then the same way Mary loses all sense of herself.
They bring out an extreme trait to each other.  

Answer 2

Mary Warren is a character in The Crucible by Arthur Miller. She is the servant at the Proctors house after Abigail was let go. She is aware of the truth, and she knows that there is no witchcraft in Salem. She also knows that both Elizabeth and John are innocent. However, when Mary tries to help, she is too weak to do so. She ends up being dominated by her fear of the girls, and she accuses the innocent of witchcraft. She is Abigail's foil because her insecurity and fears contrasts with Abigail's confidence and decisiveness.
