Wow! I heard of this case several years ago, but had no idea it was still ongoing. Glad it appears to be settled now except for the sentencing. I don't know if Australia has the death penalty, but being locked up for life will at least keep him from doing something similar again.
I do well and truly hate this cult for what it does to otherwise perfectly wonderful people and their families, but violence is not the answer. Far better to keep exposing the evil chicanery its leadership uses to keep their mind-control victims under their thumb. Especially in Australia, there's a chance their self-serving policies may cost them any government protections they now enjoy, especially their precious tax status. I hope the penalties and taxes finally make them go bankrupt. They're already morally bankrupt.
Note: To be clear, my disdain and rancor is for the organization itself and the policies of its leadership, not the individual members. Many of the rank and file followers are true believers who are trapped in the Borg, for one reason or another. It's just too bad they can't or won't open their eyes to what is happening all around them.
