When you really think about it JWS are indoctrinated to worship the Watchtower Publishing Corporation and everything it states, teaches and proclaims, irregardless of contrary scriptural or even secular support.
In terms of sociological, theological and perhaps psychological what could possibly go wrong with that working associated agenda toward following devoted adherents ?
A whole lot in my opinion.
Commercialization and religious teachings should never be mixed or supported from one another, that combination is sure to always result in a folly of corruption and harm.
