Lots of folks brought up the Clinton era, and this will be where I draw my rationale. By Michael verbalizing his wishes for Terri's death so as to get rich, he was covering up his true motive: fear of her recovering well enough to talk and tell about the abuse he gave her then and now.
Use a bad thing to cover up a worse thing. It worked then and is working now.
I seem to remember one of the Communists (might have been Lenin) to have observed, "If you want to hide a knife, put a fork and spoon beside it."
Please never ever apologize for typos or grammar; it makes the rest of us who screw things up and don't atone look like schlubs ;-)
That said, I hadn't considered that reasoning . . . that at the time he might have been trying to bring folks minds away from murder. But then again, these statements bring people's minds closer to murder, don't they?
I noticed some folks talking about their own experiences and how they either make them thing the affadavits are bogus or real. I did work as a medical assistant in a public health clinic when I was in college (the unlicensed peon type of assistant.) And we had to document everything, and god forbid we scratch something out so that it couldn't be read. Any changes could only be one line through the error and then our initials next to it. Otherwise, if we were ever sued, we would look guilty no matter what the facts were.
