I'm not trying to be snarky, but does this mean you don't think they loved Caylee? Because I disagree. I think they loved her very much.
I don't have a problem with them seeking immunity, if it means the truth finally comes out. I really don't think either GA or CA had anything to do with Caylee's death at all, and I don't think they had anything to do with the disposal of the body, either. But, the way I see it, I think that this whole time, the Anthonys have been coddling up to Casey, because they felt that Casey held the key to getting their granddaughter back. They let her tell her lies, and they followed along. Sure, I don't think they wanted anything bad to happen to Casey, because she is their daughter. But, I think it was more about the remote chance that Casey was telling the truth and that this so-called nanny had taken Caylee and if they wanted to get Caylee back alive, they needed to protect Casey. The body farm evidence and hits by cadaver dogs weren't enough, but now that they have full-on proof that Caylee is gone, I think they are coming to realize that they've been duped. I'm sure hearing that Caylee's body had been found was probably the lowest moment of their lives, and now that they know they lost Caylee, reality will be sinking in, and with all hope, they will soon realize the great extent Casey is involved. I think they, especially CA, harbor alot of guilt, too. Not because they hurt Caylee, but because they didn't protect her from her mother.
