The Society already has "community responsibility" as a rationale against assuming that a witness must be given to all before Armageddon:
*** w52 6/1 p. 345 Fixing Destinies in This Judgment Period ***
Nations operate according to the principle of community responsibility. Rulers may start wars, but the people fight them. It is upon the people generally, young and old, male and female, that the enemy nation rains destruction, and not upon the wicked rulers. The nations in their wars sow death on the basis of community responsibility. Will it not be just for them to reap it on the same basis at Armageddon? Can they rightly complain if they reap as they sow, are judged as they judged, are shown the same mercy they showed? If the people either actively or passively support what is corrupt and immoral and murderous, do they not bear some responsibility therefor?... Actually, the majority of the people today lack a love for right and hate for wrong. They know the world is corrupt to the core. Yet they are apparently satisfied with it. At least they stick with it, and scoff when Jehovah’s witnesses expose it....The world is full of Bibles, in more than 1,125 languages, and a glance at its pages is sufficient to convict the world’s conduct. But the masses of people remain ignorant "according to their wish". (2 Pet. 3:5, NW) .... If ignorance during this present judgment period is an excuse and is going to mean a resurrection for ignorant ones in the millennial reign, would it not be advantageous to let all remain ignorant now? If all those not personally preached to now and who are slain by Jehovah at Armageddon are going to return in the resurrection of mankind, why preach now at all? ... Whether it is done on the basis of personal or family or community responsibility, the peoples of all nations are going to be separated into "sheep" and "goat" classes, for Jehovah says so. Those whom he slays at Armageddon will remain forever dead, for his prophetic pictures made at the time of the Flood and at the time of Sodom and Gomorrah’s destruction say so, along with the parable of the sheep and goats. Some argue that ignorance is an excuse that will gain a resurrection for many of Armageddon’s slain, such as those perishing because of community responsibility...
*** km 11/85 pp. 3-4 Meeting the Challenge of Apartment Witnessing ***
So we have to face the fact that there are some apartment building owners who have incorporated stipulations in their leases that allow them to determine who shall or who shall not call on their tenants. If the tenants are willing to let their landlords make such important decisions for them, then they place themselves under "community responsibility," and we will not insist on making calls on them. This does not mean, however, that we stop trying to give a thorough witness in such cases.
*** re chap. 32 pp. 223-224 God’s Anger Brought to a Finish ***
The pouring out of the second bowl of God’s anger reveals that all of mankind who inhabit this sea are dead in Jehovah’s eyes. By reason of community responsibility, mankind is guilty of gross shedding of innocent blood. When Jehovah’s day of anger arrives, they will literally die at the hands of his executional forces.
