Blame it All on the Devil
During this turmoil, religion reigned over the people of Salem. Embedded deeply into religion was that of the Devil. While it was said that the Devil would most likely take over weak women and children, it was all of mankind that was at risk.
According to the ministers at the time, the Devil was recruiting members to complete his work and bringing them away from the Church and word of God. When bad things arose in Salem, it was easy for those things to be blamed on the Devil himself.
