When one thinks about it this is how JWS gain their spirituality and show their spiritual strength by being more involving and assertive in their activity within the religion.
The WTS created many dubious doctrines intentionally to attract attention to the literature the WTS published, such Christ has returned and mankind is living in the last days etc.
The WTS even went as far as setting specific dates to further enhance expectations to its followers (1975) there were devised lies and unsupported calculations, nevertheless they accomplished toward their original intent of literature circulation.
You could say the WTS exploited people's insecurities and ignorance commercially, socially creating a cult of followers drawing up free labor and money.
Unfortunately this fraud with its exploitation and mental manipulation still continues to this day.
