The current state of these religions is far from static, however, and future charismatic leaders will alter the status quo, for better or worse. Even religions originally established on simple moral principles, such as Buddhism, have evolved into belief systems populated by mystical entities, and therefore have become susceptible to further negative change. There is nothing seriously wrong with the vast majority of religious movements at this point in time, and people who are sustained by a particular belief should not have their faith disturbed. We occasionally encounter people with a fanatical, even psychotic, devotion to a particular sect. Consider, that without the structured existence imposed upon them by their faith, these people could pose a direct threat to others.
Religion succeeds in many areas where psychiatry has failed.
Numerous faiths teach that other belief systems are evil, and are the enemies of God. In fact, religions will continue to fracture into more and more groups, as has been the case for thousands of years. In reality, there are six billion different beliefs on earth, since every individual interprets life in their own way. Groups are formed due to similarity of ideas, not because of identical doctrine. Gathering into clans is more an aspect of human behavior, and primate behavior in general, than it has to do with spirituality.
