These are people who don't value life, not even their own. Unstable is not a problem to them, as long as they can go out with a big bang. These are intelligent but not rational individuals driven by religious hate. Dying to advance the cause is among the greatest honors members of that cult can achieve. Given that this culture has already delivered to us the child suicide bomber, this is not particularly outrageous in the scope of activities that our enemies engage in.
The course of the world is such that either the world will become rational or that all the people of the world will become casualties of the devout; a critical mass is a principle of aggregate instability.
While some religions have a history of non-aggression, many have a history of intolerance; the two shall always meet and contend.
