I am very sorry about your condition, Coldwater Creek and I will pray not only for you but your family. Unlike you, however, it seems that the woman and the husband were completely alone during their illnesses. Yes... the family did speak out at the trial; however, it was very unclear if any sort of care/support was given during her downward health slide. No... of course your daughter shouldn’t put a pillow over your head. You have obviously made your wishes very clear to your family and for that.. I completely applaud you. They fully know where you stand and what your belief system is all about. In this article, it sounds like the wife begged her husband to end her misery. That is where everything becomes more traumatic and lines seem to blur. It is one thing to take care of an obvious terminal person. However, it is another thing to take care of them yourself with failing health and the person begging you to end their life. I feel so sorry for this man for many reasons... the main one being that it didn’t seem he had any sort of outside help that could clear his mind or assist with a terminal issue. God Bless.
If the basis for belief is compassion, then lines indeed get blurry, because that is emotionally driven. If the basis includes "don't do murder" - well that is an unblurable line.
The question of the man's mental and physical ability is a separate matter.
