Maybe this sutta can be useful? AN 10. 104
Case 3
The grandmother had a bad view about what is wholesome for the baby, so the results (kidney failure) are very bad, suffering. Her intention is questionable. I think it is guided by carelessness, she is not cautious. Why is she not cautious? Does that really show concern with the welbeing of the baby? I think one can question that. She thinks and acts uncritical and that is dangerous and i think also blameful. At least when she is not sick.
In my opinion the grandmothers intentions are guided by carelessless and therefor cannot really be designated as good. In some sense it is quit immoral to act as such a daredevil with a baby.
