When people are confronted with something beyond their control, they tend to turn to the supernatural.
For instance, ancient Egyptian civilization was completely depended on annual floods of the Nile; This had to happen on the right time, and in the right amount. The outcome would determine the difference between prosperity or misery, order or chaos, life or death. When the river didn’t do what was expected, people asked why; What is the meaning and intention of this? What did we do wrong? Why are we punished? They wanted to negotiate with the greater powers to make up for their wrongdoing. Here religion comes in; It gave them the feeling that by rituals and sacrifice they could do that…
Judaism has 630 rules. Follow them (for Hebrews), and the world will run smoothly (?). Violate one, and something bad will happen. This archaic conviction is still practiced by (some) orthodox Jews. To sin, to offend one (or more) of those 630 rules is the disturbing factor that will result in punishment.
What about Islam? What is the main disturbing factor in this religion? In the Koran one thing stands out regarding this issue: Infidels. Could it be that (regarding to Islam) as long as there are infidels, the world will be punished by disasters, diseases,...,corruption, injustice, etc…?
The main disturbing factor in Islam is different factions of the Faith: the Muslim world isn’t in a fight against the Infidels, it is in a fight to determine who gets to fight against the infidels, with the rest of the faith united behind.
Wars in the Middle East, terrorism, sponsoring religious schools and enforcing Sharia Law - it is all just a pissing contest to prove to other Muslims how worthy of becoming Caliph you are.
