I think it's silly to take the stance that she looked "beautiful" or the same after the episode that started her on the road that lead to her death. If one believes that life is precious, it's about the inside, the soul of a person if you will, not their outward appearance. This is why it's become harder and harder for me to support so-called "abortion rights" and the "right-to-die." How can anyone argue that the soul of a person ever is, or becomes irrelevant? If in a rational moment someone expresses to a relative, or their doctor, the wish to die rather than be kept alive by extraordinary measures, I have to respect that. But short of that rock-solid evidence of a person's intent, I think it becomes dicey. In this case, it all looked too much like a fed up caregiver ready to move on, whatever the cost. Schaivo's refusal to turn over care of Terri to her family was shocking IMO. He was hell-bent on ending his own agony, not Terri's. And he continually, even after her death, stuck a shiv in the backs of the Schindler family, happy to inflict whatever pain he could. A truly odious person, he is.
I saw beauty in her before, after, and even at the end because I saw beauty in her soul.
He always had the option of moving on, simply by divorcing Terri. The family begged him to. There was something more evil here than him being "fed up" or "ending his own agony." He had been cruel to Terri and hateful to the Schindlers over the years. You see the same evil when you say, "he continually, even after her death, stuck a shiv in the backs of the Schindler family, happy to inflict whatever pain he could." Michael was -- beyond a reasonable doubt -- moved by hatred when he killed Terri.
Money was also a motive. He wouldn't divorce her because her estate might be worth millions in book and movie and TV rights. Michael has always been a hound for easy money and if it's dishonest or if it profits from his wife's blood, why, so much the better.
