The other fact to be considered and taken into account is that these evil perpetrators would exploit the two witness rule for themselves as means to escape punishment if they were caught and identified.
There are other evil maligning irresponsible things JWS do under this same premise to be realized.
Or is this obedience so profoundly rooted?
Yes obedience to protect the namesake and image of the organization, lying if it were to be advantageous and necessary.
Example of this can be seen when by one of the GB members A. Morris who recently stated in a JWorg. broadcast that the organization wasn't aware that child sexaul abuse was an illegal and unlawful crime.
That's what I would call deliberate outright lying to protect their own responsibility and moral justification.
