A few final thoughts;
This issue is NOT the same as the Susan Smith or other recent high profile cases. This woman is clearly a lost soul and had no obvious self-serving motivations which led her to this unthinkable act.
There is actually much compassion for this woman, horrible as her deeds were. There are a few angry people calling for exceution and/or torture (witness a comment or two above) but many more address the extreme sadness of the event, and recognize the utter madness of the murders and the woman who committed them. The press may have hyped the volume of death penalty calls - but I think it is clear that most people (even Texans) are simply shocked and saddened by the event - and willing to the let the legal process work throuh in its own time.
Standing by his wife? Yes, this is a good thing, but I can't help wonder where he was standing before this ... and why he didn't see it coming. I cannot help but wonder how he can so easily talk to the press about his feelings and why he doesn't just act his support for her without explaining his position to the inquiring world ... but I cannot know the details. Maybe there's more there then I can see.
And if somehow the death penalty is the result of the legal process, I expect its application would be a mercy, and her husband and family could continue their support of her through this end. I would. But it doesn't look like that will be the direction this one goes.
