Do Destructive Cults Fail?

I think most cult leaders are kind of like a joseph stallen. They might neutralize that person or take them out, because they want their authority to be absolute and unchallenged. It depends on the group and whether or not the group has assets. For example, when elron hubbard died, the founder of scientology, his estate was estimated at over 600 million dollars. David mesevige took over because he was at the right place at the right time. Why do destructive cults fail? Well i think most commonly they cross a line of criminality. That's what happened to keith reneri.
