Being seriously ill isn't (or at least shouldn't be) the default condition.
I agree...butting into a familys decision should always be discouraged, but when the family makes a decision, that places a seriously ill child in even graver danger, by denying medical help, well, that is something I cannot even fathom...
Which is more important?...preserving the family decision making ability when it comes to medical treatment, even if that decision will harm the child even more, or is the greater obligation to restore the child to health, so that the child can eventually become an adult, and make the decisions for himself?
