Its a means to retain members, apply fear guilt and obligation.
The reality is people who are JWs are Witnesses for the WTS and its leaders FDSL (GB) by their own creation and doing.
The JWS organization is game for men to empower themselves ( God channels his holy spirit to ) and make money which they live and languish in.
Simply really but the consequences are extremely dangerous and harmful to those involved and maybe toward humanity in the end.
You might say its a self made Kingdom of their own devise.
