I'm not the poster you addressed the question to but would suggest if those variables above were applied, that both or one of them would have more agency, more independence (less codependence), and more of a support network.
Were that to be the case in any direction, this horrific situation would not have unfolded to the proportion it did over the years.
JMO but I also view this situation as a folie-a-deux involving high levels of conspiracy, paranoia and departure from reality sufficient to be called 'delusion' bordering on psychosis and have always said that.
To me, it's remarkable there's been no defence to suggest severe mental health problems that could mean either one or the other were not wholly culpable for their actions. I'm sure the barristers would have wanted to explore this side of a defence.
JMO MOO
Yes indeed, if either of the defendants were suffering from severe mental problems bordering on psychosis one would certainly expect that to have been shown in the evidence, and as far as we know it hasn't been, so what do we conclude? (Although I would caveat that the media reporting of trials is always incomplete except in the extremely few cases where someone publishes the transcripts, so we can't say for sure that certain things haven't been said in evidence.)
I think I read that the defendants accumulated lots of parking fines so it must be possible to trace at least one vehicle. I am looking at this from the point of view of what evidence would help clarify on some points. Perhaps none of the cars went wrong, other than the two we know about. Perhaps they all went wrong. Perhaps only some of them did. The evidence is surely out there.
Napier Marten, CM's father, by the way is a craniosacral practitioner:

He also thinks he has met "many First Nation ‘cetacean’ people". (Same link.)
Cetaceans are an infraorder of mammals that includes whales, dolphins, and porpoises. So he is saying that he has met many indigenous whale or dolphin people. We can make of that what we will. "Cetacean people" seems to mean something different from people who are interested in whales, work with dolphins, etc. - activities that AFAIAA are not known to be especially popular among indigenous people. He is clearly not trying to be insulting or sarcastic when he uses this term. He is not using it in the nasty way that some people use a phrase such as "cat woman". (IMO.) So I wonder what he means by cetacean people.
I haven't had time to investigate what it is that craniosacral practitioners practise, but I've noticed that the phrase "biodynamic" appears close to "craniosacral" quite a lot. "Biodynamic" is a Steinerite word. Is there a connection there?
The self-described meeter of indigenous cetacean people also sent a private investigator after his daughter in 2017 and 2021:

FWIW, CM says she stopped speaking to "one of her family members" two years before she met MG:
Constance Marten described the moment she woke up to find her baby daughter had died, and told the Old Bailey: “I don’t think it’s ever something I will move on from”

She met MG in 2014.
