Evil Cults actually have a definition. First, they need to be a group, with characteristics such as having a sole leader, fixed beliefs, and exaggerated creeds. Next, they must promote doctrines that are anti-science, anti-humanity, and anti-society; otherwise, they could very well become public welfare organizations. Of course, some public welfare organizations might eventually evolve into cults, like radical animal rights groups. Lastly, they inevitably aim to achieve certain goals and will offer some benefits to potential active members in the early stages.
As long as you grasp these three points, you can accurately identify an Evil Cult every time.
