I'm not sure how you would know his motivation for doing what he did.
I didn't know Mike Rinder back at that time (or presently). But if he was a true believer, and he committed crimes, I would think he did it because it was part of the "scriptures", and it was the "greatest good".
It's possible that the fear of being disconnected from his family was a motivation, but again, how would you know that?
I simply repeated Rinder's reason for staying. It's in the part that you snipped. Here it is again:
Earlier I said:Also from the Aftermath transcript, above, Rinder states: "And the reason that I had stayed, was because of my children, my wife, my mother, my brother, my sister. And that if I left, I would lose all of them."
During the years Rinder had "stayed," he committed crimes against persons for the unlawful purpose of silencing or destroying them. The "reason" he stayed and committed crimes against such persons was not, as some people argue, because he was brainwashed, but because he was extorted. Relevantly, he had to know what he was doing.
