One couple punishes a misbehaving child by withholding food, and she dies. They go to prison for murder. Another couple withholds medical treatment from their child and she dies. The wife gets off scot-free, and the husband goes to jail (not prison) for just sixty days. Why no prison? Because they're Christians.
Was it lack of intent? No, in fact, the parents, Carl and Raylene Worthington, knew exactly what they were doing, and did it deliberately.
Were they ignorant? No, in fact the Christ Church to which they belong has a long history of children dying from medical neglect. Christ Church is such a problem that the Oregon Legislature has passed laws specifically aimed at the church's practices. The Worthingtons knew their daughter might die from their neglect.
The simple fact is that the Worthingtons knew exactly what they were doing. They knew full well their daughter could die, because other children in their church have died from easily cured illnesses. The Worthingtons killed their daughter, deliberately and with forethought. Their only excuse is that they believe God told them to do it.
So as far as I can tell, the only difference between the Worthingtons' murder of their daughter, and the couple convicted of murder for withholding food, is that one couple claims God is on their side, and the other couple claims the child was being punished. Both couples thought they were doing the right thing. Both couples were grossly, horrifyingly wrong.
What difference does that make to the dead children? Both suffered, both died for no reason, and either could have been saved by their parents.
The only argument you can make that would get the Worthingtons off the hook is if you believe that parents have a right to kill their children, so long as God says it's OK. That's what Abraham tried to do to his son Isaac, so some Christians might see why it's OK to kill your children: If God says it's OK, then it's OK.
As for me, if God told me to kill my children, I'd tell him to go to Hell where he belongs.
