Willard concluded his entries with a final four points in which he gave his final opinions about the validity of the possession case. In the first point he stated that Knapp's distemper in no way can be counterfeit on the grounds that it was physically impossible to fake such actions. The second point refers to whether or not her temper was natural or diabolical, in which he stated, because of the length of her convulsions and the strength of her fits, he believed them to be diabolical. In the third point he concluded that even though many were skeptical of the fact that the devil talked through the girl, he was convinced. He stated on several occasions she spoke with her mouth closed, her throat would swell up like a balloon, and the voices that he heard were not her own. However, in the fourth point he said he has strong doubts about Knapp making a pact with the Devil. This is because she is so contradictory about the facts, and what happened in her supposed meetings with the Devil. Willard went on to give several powerful sermons in the village of Salem during the Salem Witch Trials in 1692, as well as discredited evidence of conviction for several women during the trials, stating that the trials should be held in a "fair and legal way". After Willard stopped entries into his journal it has been a historical mystery what happened to Knapp. However her case has been cited and used as examples by various historians.
