With a sort of fixatation on proximate causality, Your worries about "... promoting conflict" are rather circular, are they not?  The conditions that assure conflict stem from conflicts of interests which are inherent in the economies of life.  Organisms are not interchangeable, not even humans or human societies.  

I promise, Islamists do not share your confusion.  The demand of Allah is the triumph of his law - fidelity to which vast swaths of the population sincerely mean to keep.  Psychology really doesn't come into it.  There is order it's law has always implied.  The same applies to all  inheritance: All the noble intentions in the world will not yield the fruits of our civilization if the way of life is left to decay. To living things, among which I count civilizations, equilibrium and death are one and the same.

Small wonder our "experts" are perennially lead about by the nose by Islamists. Small wonder fewer and fewer trust the wisdom of their deracinated 'intellectualism'.
