Having listened to all the material posted I think Matthew's fate was sealed the moment he accused Ronnie Hunter of slander. Matthew refused to play the role of the cowed Witness in the face of the elders interfering with his family but took them on at their own rhetorical game. Faced with the claim that they had acted improperly Ronnie Hunter decided Matthew simply had to go in order to uphold his own righteousness and he did everything in his power to accomplish that end.
You're probably right re. Ron's involvement. I know for a fact that my parents had been pestering the elders in Matt's congregation to get something done about him (and cardboard ninja). They'd been gathering evidence against him based on his on-going friendship with my wife and I, as alluded to in the recordings; they'd gone on holiday with us, a holiday that had originally been planned with one of the elders on the original judicial committee.
That being said, Matt had moved house and hadn't been to a meeting for around 6 months. They actively pursued him very quickly after his 25th December encounter with Ron in the Bishopbriggs Kingdom Hall.
Ron likes to play Mr Meek and Mild, but it should be apparent to even the most pro-JW listeners that the guy had an agenda and could barely contain his ire at Matt's audacious questioning. Notice how, when seemingly backed into a corner regarding his own allged slander, he started asking Matt theological questions. Matt's replies gave Ron the ammunition to relaunch their investigation against him.
That's where the lack of ethics come in;
- Ron was one of two elders who had "shepherded" Matt and his wife
- information disclosed by the couple at these visits where re-visited by Ron during his confrontation with Matt
- Ron became the chief accuser against Matt
- Ron was the chief witness to the accusations against Matt
- the other witness to the accusations was the other elder who had "shepherded" them
