BW, I distinctly recall that QfR, from my "read every WTS publication I could get my hands on" youth. There have occasionally been threads started here about whether JWs would kill if the WTS told them to, and generally the posts have been "no way, impossible, ridiculous." Your quote makes it clear that, at least at one time, the WTS did in fact propose such a scenario. The same subliminal message in the following quote:

The program also included upbuilding music and singing by the student body, the showing of slides by President Knorr in which the missionary accomplishments of the Society thus far were depicted, and finally an excellent dramatic presentation by the students entitled "Let Us Conform Ourselves to God’s Eternal Principles." At the gate of an Israelite city it showed three judges hearing a case involving the alleged accidental death of a fellow Israelite. God’s laws had been broken. There had been false testimony, bribery, blackmail, bloodguilt. The older men listened to witnesses, sifted the evidence, and brought in a judgment against the wrongdoers—death by stoning for two of them.
As those judges of Israel conscientiously administered God’s righteous requirements for his congregation, so congregation committees of our day have to do. The backdrop provided by artists and the realistic costumes worn by the student actors served to make this powerful drama live. The same deep-lying and eternal principles of God apply in our day. Only by conforming our lives to Jehovah’s will can we gain peace and happiness.
"Kill them all, and let God sort them out."
