That paragraph you quoted reminded me of my conversations with die hard JWs. I have tried reasoning with the most stubborn of JWs (no heated name calling or anything silly), and in some cases, made me wonder if they were "on the spectrum". One particular JW was so absurd in his ability to (cold-heartedly) reason through WT goggles it just makes you shake your head in disbelief.
The recurring theme being that extreme indoctrination = love. Anything beyond that is "unloving". They literally redefine words, as per cult practice. There was no sense of basic human compassion/empathy unless they were a "repentant JW" (read: submitted to current WT counsel).
WT says that the Pharisees were cruel, and this translated = "they did not teach what the we teach about God (trinity, hellfire, soul, last days etc).". Human ethics/morality doesn't come into the equation because in a cult doctrine is more important than the person (although they rarely see it). The so called greater good = WT propaganda.
Simple examples of WT "morality":
A bad person - someone who tells you to take some time off meetings and not worry about underlining your WT
A good person - someone who tries to "support" you on field service by making you feel guilty over not going out.
