This family is middle range dysfunctional. I've heard much more hideous things regarding other families throughout my career thus the Anthony's are nothing in terms of sick families.
Big issue in the family was/is CA having a personality disorder. We don't know her diagnosis but she appears partially responsible for who her daughter became. If CA had married a man who had a different personality from GA then Casey might have at least had some boundaries and discipline.
CA is avoiding and denying that her precious baby was responsible for Caylee's death. I'm not even denying that the death could have been an accident but still, CA isn't seeing her daughter's level of emotional disturbance (the immaturity, troubling defense mechanisms, signs of psychological issues). CA wants to reuinite with her child. She loves her but isn't aware that parental love also includes boundaries and limits.
GA is a man who gave his wife all the power because it was easier for him somehow. I feel empathy for him. He likely doesn't want to ever see his daughter. He knows that she's responsible. GA is suppressing his rage b/c he's trying to keep his marriage at 'peace'.
LA was a bystander. He gave info to the cops and helped out tremendously. He gave as much as could given his role in the family (i.e. clean up man, ignored parentified child, mediator). I've read all his depositions. He did not lie on the stand. He presented his current feelings and I can't blame him. He was trapped and I completely understood why he didn't want to deal with the prosecutors before the trial. It was unfortunate that the SA was so clueless as to human nature as to not see LA's huge conflict. Even with it he gave damaging testimony to her case ('spiteful b', her purposely avoiding him, her demeanor during the 911 calls, etc).
LA probably lost his job b/c of this case. He's probably not happy that she got away scotfree. He likely was hoping for a 15year sentence or so. Even though LA sees her for what she is, b/c he sees his role as 'protective older brother' he's the one who'll likely fall into her trap in the future and give her another chance or not (GA had testified to FBI that LA's relationship with his sis soured b/c she lied about pregnancy). The one way she'll get LA back to a semblence of relationship is by telling him everything that happened with Caylee in the last few moments. LA likely won't 'forgive' but he'll give her a chance b/c of their former close bond. He's her bro, he loved her all his life, it's not a bond that will be easy to break (especially as he likely views CA as partially responsible for his disturbed sister's behavior along with considering FCA's immaturity and ability to be 'led' by others as part of her issues).
