Hello everyone... just got done reading thru the whole thread *shew*.
It seems to me when anyone expresses a belief that the Anthony family dynamic had anything to do with how Casey turned out, or Caylee's murder, there are some that automatically think you are 'making excuses' for Casey's behaviour, or implying that you don't think Casey should be punished, etc. So, let me get these things straight before I comment on what I believe the psychological makeup of this family to be.
1) I don't think there is any excuse for Casey's behaviour. I don't think there is any excuse for Casey murdering her daughter. I do NOT blame anyone but Casey for what happened.
2) Being as that I believe Casey murdered her child, I think she should be prosecuted to the full extent of the law.
With that said, I will tell you that I am the type of person who loves to figure out what makes people tick and I'm highly interested in abnormal psych/personality disorders/mood disorders, and personality typology. When someone says "who cares WHY someone did what they did?".... I must disagree whole-heartedly, because I love to learn and try to figure out the "why's". To some, that might seem like a waste of time... but it is not to me. I have also seen a tendency for some people to misconstrue what some of us mean when we say we are trying to 'understand'. When I say I am trying to 'understand' Casey and why she murdered her precious little girl, I am saying that I'm trying to figure out what makes her tick, what disorders she might have (if any), and possibly get some insight on what creates a child-murderer. I am NOT saying that I am trying to 'BE understanding' of Casey as in 'poor Casey she had all these problems, it's not her fault, she couldn't help it', etc. In any case, I hope I have made the distinctions clear. With all that out of the way, here are my OPINIONS on the psychology of the Anthonys:
Cindy -- I think Cindy has Histrionic Personality Disorder, as described by the DSM. After going over everything that is available, thanks to the sunshine law in Florida, I see nothing that leads me to believe that Cindy is Borderline, a Psychopath/ASPD, or Bipolar. In my opinion, HPD covers pretty much everything about her bizarre behaviours. I also think Cindy may have NPD as well, but I'm not as sure about that one.
Casey - This one will be short and sweet -- I think Casey fits under "Antisocial Personality Disorder" quite well. Some professionals differentiate between ASPD and Psychopath/Sociopath, and some do not. I think ASPD fits Casey according to the criteria set forth by the DSM.
George -- I don't think George has any sort of major psychological disorder. I think he's lazy; I think he'd rather live off someone else than work to make his own money; I think he's weak and a pushover... but I don't think he's mentally disordered in any way. If I HAD to choose something for George, I'd say Dependent Personality Disorder.
Lee - Lee is eccentric, no doubt. But does he have some sort of mental disorder? I don't think so. I believe he might have a bit of anxiety that causes him to laugh at very inappropriate times and he has a completely misguided loyalty to his murderous sister (IMO), but I don't think there are any major psychological issues with him.
Now, the question of nature vs nurture when it comes to Casey... I think it's a little of both. I think people may be born with a tendency to ASPD (or some other disorder; I'm just using ASPD as an example because I think that is what fits Casey), but that it can be aggravated and maximised or minimised and blunted (for lack of a better word). Not all of those that are dx'd ASPD or even psychopathic are murderers. It is my belief that IF Casey had been forced to face consequences and punishments, and not constantly let off the hook by Cindy -- this murder MAY have not happened. I think that Casey would STILL have had issues... perhaps she would have still been a thief, a liar, and sexually promiscuous, BUT... maybe, just maybe... she would not have turned out to be a murderess. Do I blame Cindy for Caylee's murder? NO. Casey killed her daughter. But, as I've mentioned before, I think there is value in trying to ascertain WHY people do what the do, make the decisions they do, etc.
So those are my ideas, take'em or leave'em. When it comes to abnormal psych, I have read a lot, studied a lot, and researched a lot (psych was my major in college) BUT... I am NOT a professional, and these are only my humble opinions. Thanks for reading!
