Or how religion becomes deadly

The author here the study of Mormonism. And goes even further, seeking what led to murder two brothers in the guise of the most extreme branch of this religion.
Brilliantly written, we understand in the first part that religion which for us French, we are almost foreign. Full of subtleties and with a rich history of surprises, with a complex culture, it is not only the religion of polygamistes as often can be the shortcut.
She is a very young religion is now very powerful, very rich product via its own university including notables in politics and the US economy through a system and a culture of excellence running smoothly.

In the second part, little by little we understand how two lost souls can cling to beliefs, as crazy as they are, to give meaning to their lives and come to the unthinkable. A study of extremism that can apply to all religions and that explains in part the crazy and irrational behavior of these extremists.
Exciting and rewarding!
