If I believed in a Religion that was pushing me to kill, I shall become an atheist, I would not think: "I am forced to kill."
Moreover, according to the Christian Religion, many things would be prohibited, as fornicate if you are not married: how many believers follow these directions?
Luca,
The text do exist in all religions.. but Europeans got themselves free from religious influence on social life long time ago, and confined it to churches.. (Man and his God)-- while in the mideast they didn't.
Muslims today have a real challange.. they either renew their religion in light of modern humanity's achievements of equality and human rights.. etc, or simply will take the first exit from history.
There are honest people regardless of religions. There are criminals regardless of religions.
Religions, all, are human inventions.
Nobody can be so vile to say: "I kill in the name of God." And if God were to exist... then he should justify his actions.
I give you bad news: in a few centuries humanity will become immortal; thus any Gods will have to appear on Earth
