Regardless of how they act or what they say...they have personally suffered the loss of Caylee at most-certainly their own daughter's hand. And are now they're facing the loss of - regardless of how you may feel about her - their daughter.
Who knows what goes on behind the curtain. I am certain though that nothing they say or do can possibly change the hellish reality they awake to each day. I wouldn't wish it on anyone.
After reading your post, I had to re-think what I was going to type. I surely wouldn't want to find out how I would feel and I do have some empathy left for the Anthony's. They will definitely suffer for the rest of their lives.
That being said. I will probably watch the show, but I have a feeling I will feel like I just got off the Tea Cups at Disneyland.
