You are incorrect in this statement. Judge Greer has ruled that she is to be starved- no food or water is allowed. Now you tell me how that is humane.
No, I believe you are incorrect. Judge Greer did not substitute his judgment for that of the husband. Rather, he decided that the husband could properly make that decision. If tonight, the husband had (what I suspect you would think was) a "Damascus Road experience" and decided to continue food and water, Judge Greer's order would not interfere.
Your real objection here is to the decision-maker not the decision. You (and others here) don't think the husband should be the one to make the decision (because you don't like him, suspect him of ulterior motives, etc). Those, however, are precisely the matters Judge Greer has ruled upon. He has now ruled that the hospitals, etc must follow the instructions of the husband which he (Judge Greer) and the appellate judges have approved.
My argument is simply that the husband's instructions, once the evidence against him has been reviewed and found wanting, should be respected.
