I have been concerned about JWs starting to think like this for a very long time.
The GB has been priming the JWs with messages that Loyalty™ to the Organization™/Jehovah™ (in other words, doing whatever the GB says and following written instructions in the Publications™) is more important than any relationship. They've published statements to the effect that "even if what we tell you to do goes against your values, you should do it anyway." Ignore all your ethical boundaries. Do things that make normal people shake their heads and wonder "WTF is wrong with you?"
They have already convinced the vast majority of JWs to cut all ties with Disfellowshipped™, Disassociated™, and more recently Inactive™ people, including their own children, including children who were never Baptized™ as JWs. It's emotional and psychological torture, fully endorsed by Watchtower. They have said, in the past, that only the laws of the land prevent them from endorsing a Theocratic™ solution that would have been utilized in Bible Times - when "cutting off" someone (including your unruly child) meant taking them to the public square and stoning them to death. They have not retracted this statement but maybe the "new light" has somewhat modified their position on it - maybe it wouldn't be too much of a stretch for someone to take the Loyalty™ statement to the very extreme.
*** Nov 15, 1952 Watchtower ***
We are not living today among theocratic nations where such members of our fleshly family relationship could be exterminated for apostasy from God and his theocratic organization, as was possible and was ordered in the nation of Israel in the wilderness of Sinai and in the land of Palestine. "Thou shalt surely kill him; thy hand shall be first upon him to put him to death, and afterwards the hand of all the people. And thou shalt stone him to death with stones, because he hath sought to draw thee away from Jehovah thy God, . . . And all Israel shall hear, and fear, and shall do no more any such wickedness as this is in the midst of thee."-Deut. 13:6-11, AS.
Being limited by the laws of the worldly nation in which we live and also by the laws of God through Jesus Christ, we can take action against apostates only to a certain extent, that is, consistent with both sets of laws. The law of the land and God's law through Christ forbid us to kill apostates, even though they be members of our own flesh-and-blood family relationship.
