A schocking report in the Guardian made me think. In Ghania a 72 year old woman was burnt as a witch;

This terrible inicedent was carried out by several people including a Christian pastor and several apparently otherwise ordinary people.
This just goes to show that if you believe in a paranormal deity and supernatural evil you are a very short step away from this type of behaviour. Most liberal theists might try to disagree with me, but if they do hold such beliefs all it takes is a change in their personal or social circumstances or a charismatic leader and their god and religious beliefs will be invoked to explain it and drive their actions to rectify it. It matters not how liberal the theist is, how westernised or civilised they think they are, if they truly believe evil is affecting their lives they will take the actions they believe to defeat it.
To paraphrase something I've heard; Good people will do good things and evil people will do evil things but for good people to do evil things, it takes religion.
