I agree with you...and I think at the heart of it that's one reason she murdered her children. If she killed herself, he'd get them...if she left, he'd get them, at least part of the time and full-time if she was hospitalized again.
There have been plenty of cases of husbands or ex-husbands killing their own kids to keep the woman from having custody...Women don't do this as often, but I'm sure Andrea's is not the first case. Even with her bizarre mind-set, I can't help but feel this was part of her motive for murder...to keep Russell from getting them (if she died) or taking them away from her.
Believe me, Appy (may I call you Appy?), I'm not defending her one bit. What she did was evil, whether she was in the grip of mental illness or not, it was evil...I'm just suggesting that Russell's self-centeredness and lack of empathy may have contributed to his wife's hateful decision.
Face it. There is little good in Russell and any that exists will NOT be exposed by the media. They are in full witch hunt mode. By the time this is over, every homeschooling family is going to be led by a Russell clone
