The admission Fred Franz made at the Walsh trial has always stuck with me...
...that the WTS was, indeed, fallible and had made egregious mistakes, but that the R&F still were required to accept whatever the Org said, as though it were infallible...
...and what's more, if they didn't, they were - for all intents and purposes - deserving of death, simply because the leadership believed (i.e. convinced themselves without actual proof) that they were acting as God's agency.
Deconstruct it down to that core description - without all the religious syllogism - and quite frankly, I doubt there's a single reasoning person on the planet who wouldn't think it sounds f**king insane.
