Many members of the audience may say that Miller has presented Abigail in a manner that shows her character to be wholly evil however I do not think this is the case.
I think this because she is not incapable of showing love or passion. Though the audience sees near the beginning of the play, Abigail has been hardened, this is due to witnessing Indians murdering her parents, "I saw Indians smash my dear parents' heads on the pillow next to mine," she is not emotionless (the use of dear is an indicator of this). This is clearly shown in the scene with Proctor as she is desperately trying to win him back through stage directions, "she clutches him desperately", as well as dialogue "I look for John Proctor that took me from my sleep and put knowledge in my heart."
Here you see her at her weakest, she is begging him to return to her and showing no signs of the harsh exterior the audience gets to see later on in the play.
I believe that if a person is wholly evil they will not harm another person due to being fuelled by jealousy or hate but purely because they wanted to. This is not the case for Abigail; at the beginning of the play Abigail was presented as being truly in love with John Proctor and this love is what drew her to accusing Elizabeth Proctor of witchery. As well as causing her to drink "a charm to kill Goody Proctor" so that she could be able to run away with John and have him to herself.
This is not to say that I do not believe that her character is evil in many respects. Her ability to control...
