Most people that join a cult don’t even think about them in that way, and that’s what makes these groups dangerous. They rely on charismatic leaders that sway the minds of people on a low point in their lives, promising answers to every question and doubt, even the ones humanity has none to offer.
What they ask in return is absolute devotion, often monetary compensation, and putting the group, its leader, and their ideals above your own dignity. These are some of the most dangerous cults that have appeared throughout history, and what made them so dangerous.
