Half of the Sermon on the Mount is basically Christ saying: "Mind your own business, and leave the judging to God." But the antidote to ISIS is a matter of economic stability and good governance. I am not convinced that this is a cultural movement or a matter of religious perspective. IMO it has much more to do with a lack of opportunity. People get ugly when they have no hope.
Yeah. ISIS is a globalized version of the inner city gang/drug wars that peaked in the late 1980's and 90's. Folks with severely limited resources are abandoned with no hope in a careless system. Their chosen religion is the glue that binds their anger in to a cohesive mass that provides their power. Sort of a modern day Mongol Horde that is able to coalesce by via social media rather than horseback.
