I agree JWs preached (if that's what you call it) door to door to save their own necks not out of love/care but for their own elevation/promotion in the group. They're jealous/haters for the most part. I use to hear a narcissistic-sociopathic JW boast continually to her daughter that other beautiful young teenage girls weren't getting eternal life as she was -- like bummer for them - they're pretty or prettier (and had dedicated, responsible, parents, who drove them to ballet, whatever), but they'd be destroyed. Made me sick.
Gotta love religion and the inflated egos/arrogance it promotes.
