Not only that, but I can easily add that it's not limited to a diety at all. There are cults that use the same tactics and what they are based is on recovery from drugs and alcohol. There are other ways of using the same tactics, using political causes or self-help, for example, that can harm as much as using a god or diety.
By Jove, I'd say that absolute power corrupts absolutely! Yep, you have political cults, cults of personality, new age cults around some funky bestselling book, recovery programs that depower rather than empower the self...
Critical thinking is the enemy of all of this.
