Religion is not simply a book. Book's don't say you have to do what I tell you or else you go to hell. If that was the case everyone who was unable to follow the Atkins diet would be going to hell. Religion, especially Islam, professes to be a complete way of life, and we see that the people who follow this are committing suicide bombings in it's name and killing people in it's name. So yes you can blame the religion for its followers behaviour.

"We submit to the majority because we have to. But we are not compelled to call our attitude of subjection a posture of respect." Ambrose Bierce
