"The question is not whether he has a conflict it's whether he may have a conflict."
It all depends on what the definition of "is" is.
FL$: It all depends on what the definition of "is" is.
No, Judge Greer resolved that question (and in the manner you urge) long ago. He found that both the husband and the parents might have a conflict. That's why the withdrawal of the feeding tube was by order of the Court and not by order of the husband.
The husband (because of the possible conflict) then petitioned the Court to act as Terri's surrogate to make the decision granted her under her right to privacy under the Florida constitution. The Court did that, after the lengthy trial and concluded -- by clear and convincing evidence (which is an evidenciary standard, not a descriptive term) -- that Terri did not wish to be kept alive artificially. Thus, in ordering the removal of the feeding tube, the Court is merely honoring Terri's wishes.
What is seemingly lost on so many of the 'physical-life-at-all-costs' types is that many of us, particularly those of us who are Christians and on our way to a much better life, simply don't agree with that premise. Terri, the Court found by overwhelming evidence, was one of those who did not share the physical-life-at-all-costs premise.
What is tragic is some Republican (!) politicians would now override her wishes to cater to those harboring this premise.
