Hm, I think we'll just have to agree to disagree. IMO a doctor's first duty is to present the truth, make his/her recommendation - and then support the patient in whatever he/she decides, even if the doctor doesn't agree. And that last point is where Ree ultimately failed horribly.
I don't mean to come across as an ass, but IMO the third part isn't really an absolute. Hell, I know that if I wouldn't want my doctor to automatically support me in whatever I decide. If the doctor thinks I'm being an idiot, I'd want them to tell me.
As for the Deanna debate, I think part of the problem is that this is a lot more complicated than should she or shouldn't she get an abortion. The most important part of this is the fact that Deanna WILL DIE if she doesn't get the abortion, so it's not really a matter of the baby. As for the baby, as far as they know there is nothing that can be done for it, so to Vale and Ree who have no connection to it, it is pretty much a non-issue, and this is where the problems start, because to Deanna it is.
