"You loved me, John proctor, and whatever sin it is, you love me yet! John, pity me, pity me! ( act 1 scene 2 ) this shows she can be weak. She wants pity from John she just wants someone to love her and killing goody proctor is the only way she can have John.
"I want to open myself!..... I want the light of God, I want the sweet love of Jesus! I danced for the devil; I saw him, I wrote in his book; I go back to Jesus; I kiss his hand.

She is willing to put people's lives at risk to save her self.
