You know there is a theory that the hysteria of the Salem trials was caused by Rye bread, or more specifically the fungus that grows in the bread and contains Ergotamine and Lysergic Acid. If that was the case then it would not matter what religious belief the followed or whether they followed one or not; the hysteria would still have occurred but might have taken a different form. But, from what I have read it was not just confined to one area, Salem was the catalyst and the focal point but it was not limited to that area, many who were accused came from surrounding towns and villages and unless there was a widespread outbreak of rotting Rye bread I doubt that this was the cause of all of the accusations.
While they may not have instigated the accusations there were those who used the opportunity to exact revenge on other individuals or to benefit financially from the downfall of neighbors who were accused and imprisoned whether or not they were hung, burned or, as I mentioned in another post, crushed to death.
