About 100 - 200 ad the bible was put together to empower the church. To maintain this, as the world has become more educated, the church continues to amend the tenets.
When Mohammed put the Koran together is was designed to empower himself, unfortunately when he died the Koran can be picked up by any individual, who presents it any way he wants and thus he becomes empowered. To the point that slaughter and mayhem can be contrived especially where there is no law or justice to curb these acts. Thus we have terrorism at the most violent extreme.
