Consider This

I watched the documentary because a recent spate of wrong-way interstate fatalities have taken place in my area. One collision killed six members of an immigrant Indian family traveling in a small sedan. "There's Something Wrong with Aunt Diane" puts the sick idea of going out in a blaze of glory in an imminent suicide's head. This woman was evil incarnate, so--yes, I do think it would be a good thing for the documentary never to have been made. Particularly such a sensationalized, Dear Zachary-over-the-top narrative does harm. This film glorified a madwoman and (apparently very successfully) humanized her.

I'd be interested to know if the documentarians were, for lack of a better word, friends. I say "for lack of a better word" because it's presumptuous to believe a psychopath is capable of having friends. Not surprising at all, the significant people who refused to have anything to do with their work.

Look up the word "absolute", if you are not familiar with it.

You chose the word, not me.

Also, stop with the hyperbole.

If you have to resort to exaggerations, it indicates that you have a weak argument or a weak position to begin with (i.e., one that needs exaggeration).

Plus:

You are side-stepping the real issue.

If you have "absolute" evidence, I am quite sure that the investigators on the case would love to have it.

Or is it the case that you -- sitting at your computer in your basement (and probably with no law enforcement/investigatory training and/or experience) -- know more about the specific details of the case than the investigators who have studied every detail and pored hundreds, if not thousands, of hours into the case?

Enlighten us all. With your expertise on this specific case.

Absolutely!
