fogman: your example has not much to do with what I wrote. Vinuous_Beret said there are no Turkish extremist. I know, there are one. They did not kill their sisters because of psycho-logic sickness. They did because of their religion. Because they believe a daughter has to marriage the man selected by their father.

Your example is different. I know there are other reasons why people kill other people, why people kill animals and why people kill themselves. But the reason of my post was to discuss an example of extremists.

I am also not a fan of killing people especially since I do Karate sports. It is stupid but still there is the fact, that some of these stupid murders are driven by religious thoughts based in their Islamic belief. And I am absolutely sure the same applies to other religions including some crazy Christians.
