" ...she may be a witch, as it usually goes..." Based on what exactly? Nothing in the link to suggest she's anything like a "witch".
"...she did to choose to behave in a way that would anger her unstable husband" You're blaming the victim. Quite possibly (or should that be probably), he would have picked on any other "excuse" to do the same thing. Think about it. The guy does this because he didn't get included on a picnic list???? Gimme a break. How the hell can this woman NOT anger her husband? Wrong coloured socks? Food not ready on time???? Kids crying???? Any excuse will do.
"I am guessing those kids are actually adults, they may have inherited the defective mental conditions that afflict their parents, but they still have the energy of youth. The mother may be able to live with one of them." They may be adults or maybe they're adopted. Neither of us knows. But what makes you think they have inherited any mental conditions? And you're saying the mother also had problems???? Based on what? Women stay with violent husbands because they see no alternative.
"Your position is that outside forces caused her suffering, while he is responsible for his? Yes, but I am saying while his action caused the disaster, he didn't act in a vacuum." Outside forces???????? It was her bloody husband!!!!! You can't get less "outside" than that. Yes, there may be "demons" loose in his brain, but he is responsible. You seem to be doing a few extra yards to imply she's in some sense responsible, but from what's been presented, that's a real stretch.
And I have experience. My father was a bit like this guy. I wish to hell I had kicked the crap out of him 40 years ago. it was always my mother's fault, no matter what she did or didn't do.
Sorry, if this comes across as a bit of a shotgun approach. Nothing personal. But I hate domestic violence.
