Casey is also suffering from dementia and has sepsis from infected bed sores. He is old and dying and unable to take sustenance on his own. Let him pass from this life in peace.
That's going to be 80% of us someday. That's grounds to euthanize him? Keep him comfortable and let him die a natural death from the dementia or the sepsis if he really is dying, but why take away his water and food? That's euthanasia, that's not "letting him die."
Amen to that. My father passed from this very diagnosis. It is a horrible end. There is no “cure” and all these “heroic” efforts only prolong suffering.
