One should bare in mind that WTS's doctrines compile one after another in continuous framework of support of another, such when did the Gentile times end according to the WTS theology of 1914.
From that year on what supposed to happened didn't or failed, why because 1914 was wrong obviously.
Its easy to see that the JWS religion was founded upon false teachings, false date setting and not following the guidelines set by Jesus himself in preaching the Gospel as it was written... etc.
They may have been advantageous for literature proliferation in the act of charlatanism but they weren't obedient and loyal to Scripture and to further extent to Jehovah.
This video shows the inherent corruption orchestrated by the WTS and its leaders.
