But Mrs. Finn, you can bet your last dollar, would not have removed the feeding tube of one of the children, if one of them had not recovered from the accident. She would not have done that to her "blood" relative. She did it to her husband without blinking for the $! She let it ride until HE became a financial liability.
Do you know some facts beyond those in the story or are you just putting your spin on it? Even though the story is written from the 'physical life at all costs' perspective, I don't see that in the story.
I have always found it difficult to predict what people 'would' do in other circumstances. Moreover, you ascribe motivations that would be hard to know. Are you sure your a priori position in favor of extending physical life isn't coloring your view here?
