So of course any "professional" can make mistakes or have bad judgement, the same way that non-experts can. The question really comes down... in what situations do you believe the individual has the right to choose, and in what situations do you believe that an expert should step in and decide? For example, I don't think people would say that individuals should decide if something is a crime, and that the determination therefore is the realm of police, lawyers, and investigators. In the case of abortion, there are people on both sides of the fence - some believe that it's always up to the individual, others belief that their personal belief that the fetus is alive should mean it HAS to be protected at all costs. In the case of child marriages, some believe that children under the age of majority should never be allowed to marry, others believe that as parents and religious leaders, they should be able to marry a 12 year old girl to a 35 year old man. ~ In THIS case, there is even a finer line. Even if you believe the parents should be able to choose, generally, do you believe that the parents should be able to choose ANY treatment whatsoever? Or do you believe that SOME forms of "treatment" should not be allowed? And should parents also be allowed to WITH-HOLD treatment, even against medical advice? When is it time for the state to say, "No, you can't do this."? Is the answer never? If so, how do we protect the rights of children from parents who (malicious or otherwise) do not act with the best interests of their child in mind? Or is that not a goal society should pursue?
