If not, he will one day die like crazy L. Ron did and unless he repents of his cult and comes to saving faith in Christ I wouldn't want to be in his proverbial shoes when he stands before the Lord Jesus Christ in judgment.
I have little faith in that ever happening. No state Attorney General wants to tangle with Scientology. They have a well earned reputation for being the most litigious religious group in the country, and can marshal an army of shark toothed lawyers in an instant.
Miscavige is also protected by a cloak of religious cover. He can get away with things that would send any CEO to prison - or at least, the unemployment line.
His pockets are deep enough to keep the lights on until the cash registers finally stop ringing, at which point he'll begin liquidating the carcass and bones of the organization he destroyed.
