After reading books like Sapiens (Harari) and other evolutionary psychology books, it seems humans will always form religious frameworks in order to collaborate in large numbers. Combine this with the void left behind by the increasing secularization of civilization, and you get a fertile ground for any large organization to sprout their own religion, which in its initial form looks like a cult.
Nietzsche has been proven right in this regard, getting rid of God (or monotheism) just gave way to a void that is now being filled in by pantheism and paganism, in which civilizations become fragmented by a multiplicity of gods. Perhaps the solution is to have explicit religions that are designed with explicit goals in mind... however I feel this is what the ancient civilizations have already done, and the oldest religions that have survived the "natural selection" of history are the ones that have been perfected and do not lead to a cult-like dystopia.
