When Ideology Goes Wrong discusses the darkest corners of human behaviour that lead to extreme violence from delusional killers controlled by a twisted fantasy in their own minds.They need to satisfy some desperate urge in killing random victims. Then to the spree killers who come out of nowhere and strike when least expected with a hail of bullets in a public gathering, and on to the witnessing of the religious insanities of 9/11.Discussing when ideology that goes wrong is the unwanted excess of the three main faiths and how other ideologies get overtaken by misguided warped logic that leads to extreme murder.Of course history and politics play an essential role in that evaluation.
