The entire village bases its belief system on the conflict between good vs. evil, or Satan vs. God. Over and over, as people are accused of witchcraft, this paradigm gets dragged out. When Tituba confesses, she claims she wants to be a good Christian now and stop hurting people. She must renounce the Devil. When Mary Warren can’t handle the girls’ accusations, she accuses Proctor of making her sign the Devil’s book and claims she is now with God. The world in The Crucible is clearly divided into these two camps. Unfortunately, everybody’s confused about which side is actually good, and which side is actually evil, though it’s abundantly clear to the reader. It may seem like evil is winning, as one innocent person after another is put to death, but we also see that there is power in martyrdom. The innocent people who confessed are beginning to rebel, and both ministers have recognized their mistakes by the end of the play. Above all, the religion of Salem is incredibly bleak and tends to focus on human frailty and sin to the exclusion of the good things in the world.
God has no positive presence for the people of Salem; only Satan is an active force in the world.
