So it's okay with you to starve a woman who has become disabled. How do you suggest we treat people who are born disabled? Should there be a panel to decide which lives are worthy of being lived? And then what?
She is a vegetable, her brain does not function and has turned in a liquid state. And to top it off it was her wish (as decided by numerous courts) that she not live like this.
Stop forcing your views and morality on this poor women and let her die as she wanted.
