I have wondered for the past 20 years or so whether the WTS would ever cross the line. This was published in the Watchtower in 1957:
*** 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.
Yes, I do feel that the day may come when the WTS will "suggest" that the time has come for True Christians™ to act out their Theocratic™ fantasies of wiping out Apostates™. It wouldn't take much. They've already laid the groundwork by saying that they were going to tell JWs to do things that they may not understand or find hard to accept. The WTS already expect JWs to allow beloved spouses, children and other family members to die for lack of blood transfusions. That, in itself, is beyond comprehension and hard to accept because it is a passive form of homicide. Yet, when faced with this Test of Integrity™ how many JWs have gone along with it? It would be exactly the same with active forms of homicide. All the WTS has to do is say it is a Test of Integrity™ or a Test of Loyalty™, and there would be lots of JWs who would be more than willing to comply.
