I've seen plenty of patients die. I've seen some go like I'd like to go...And I've seen too many go...in a way I wouldn't wish.
Many families..and Doctor's end up torturing their loved ones/patients. And I don't use the word "torturing" lightly.
The lead up to death can be horrible...but it doesn't have to be. I can totally understand a spouse that can't stand the sight and sound of their loved one being tortured...to make it all stop.
Was a gun the right way? Probably not. Will God punish him? I don't know.
Is God a loving God...that knows the hearts of all men and women? Yes!!
Let's say a patient is gravely weakened, in irreversible decline, and has an underlying medical condition which is basically untreatable at this point. That person should not be tormented with futile treatments, "heroic" interventions, chemo, radiation, surgeries, etc. which they can't tolerate and are just burdensome for no purpose.
That's when the focus of treatment has to shift to comfort-care: meds to control pain, agitation, nausea and the other symptoms of untreatable illness. Adequate food and water to keep comfortable; clean, hygienic, pleasant surroundings. Counseling and assistance needed for the main care-giver, too (like this poor husband) who may well be suffering from depression, stress, emotional trauma.
This was a bad death. Being shot to death by one's husband is bad. Why didn't both the wife and the husband have appropriate help? Who was the doctor? WHO LET IT GET TO THIS POINT?
