Yeah, also it was the way it happened, we should not judge those times with our vision of things, different times, different values. All religions are a form of control over the peasants, Islam grew and evolved in an area with a set of political and social characteristics and Christianity the same but different ones and that's why you find the differences and the same reason that Islam and Christianity split in several branches. And you can see east Europe went Orthodox, South Europe went Catholic and North went Protestant, add to that the fights for the power.
