Well done Anna ,
JWS are not witnesses for Jehovah, they are witnesses for the Watchtower Corporation and its version of Jesus's gospel of a new Kingdom order.
The leading men of the WTS (GB) were apostate false prophet sinners, as they still are to this day.
Jesus said no one knows of time not even he, more than 500 years after the fall of ancient Jerusalem, just to add and confirm that its scripturaly immoral for humanity to set a date on their own appealing discretion.
Being opposed to Jesus's instructions for preaching his Gospel is never going to make an individual or an organization righteous in his eyes.
