Conversion is a slow process of brainwashing, as words take on new meanings, and previous religious views or hopes are seen as erroneous. Though cults which fit this pattern may seem to continue on indefinitely, even growing at alarming rates, their structure is slowly crumbling at the foundations. Because of their scholastic dishonesty and their treatment of dissenters, they never lose their reputation as a cult unless they make radical changes, which would result in loss of many members. Since members are their source of power and income, this simply will not happen to any notable extent, other than their admitting to being imperfect and subject to mistakes. Such organizations are, in effect, sealed in a course of history.
All cults seem to go down the same road.
In the end, the persecuted, if they grow, will become the persecutors. As the quest for power rears its ugly head, thousands will be discarded alongside the road, bringing great bloodguilt on the organization. The author can certainly vouch for that, having spent eight years in such a group. Former cultists may blame God or their parents for allowing them to get involved in a cult, and this has to be dealt with by others who are in a position to help, such as a support group for ex-cultists. The local church is often in a position to help, if the person can actually bring himself to inquire.
