most of what you say is true..however i’ve seen men that would rather face a charging grizzly bear unarmed than their own wives...
The burden is on those who assert that he did this for financial or marital relations to provide some evidence of problems in that area.
I don’t think he faked it, although I guess I could become suspicious. I can come up with a million reasons why he might fake it. He became insane. Aliens from outer space convinced him to do it.
None of that is the least bit evidentiary. Those that think his death was faked will have to do more than come up with possibilities backed by no evidence at all.
