I don't think anyone MEANT for JB to die.<quoted text>
At least in my theory I provide for what was done to JB with the idea that Patsy was mentally ill. I can see a mentally ill person doing all that but not a normal one.
How do you account for Susan Smith, who planned her boys' deaths and watched them die and was judged perfectly sane? And the other "normal" mothers who did horrible things to their kids and were judged sane?
It's a sad fact - some sane people will do just about anything, commit atrocious acts, even against their own children.
"Man always chooses his highest good," and it's true. After injuring JB, the Ramseys' highest good was to cover their behind and stay out of jail no matter what it took.
