Firstly, this doc is very good. Though I'd argue that there could have been more said - i.e. The other theories regarding the night the DeFeos died. That aside, Origins does prove my own personal belief of the matter. I do, in fact, think that the Lutzs experienced a residual haunting due to the horrific murders. Like an echo - it lingered, waiting to be heard. And George, feeding into this energy - be that by drugs or his own personal demons - made it worse. And perhaps the narrator is right - maybe 112 Ocean Avenue needs a certain type of person to reawaken that trauma. Or maybe getting rid of George Lutz saved not only those children, but the home itself.
