It is morally wrong to deprive anyone of life. It’s really simple.
I do not know the circumstances of your mother’s death; that is between you, her and God. But I do know that it is very odd of you to jump into this discussion which is a clear cut “right and wrong” and pound on me for...??? what I do not know.
It’s normal to remove life support from a dead body. There is no guilt associated with that. The problem comes when someone makes a quality of life judgement against another person, and that person loses their life as a result. That puts them in the position of having to either deny what they did or convince everyone else that what they did was right. There is one other choice, to admit they did something wrong. That can be too painful to consider. I can’t imagine the turmoil of having a hand in the death of another person.
I responded to one person’s post who chose to use the term moral absolutes. It was a response to that. Every response since then has been to folks like you who apparently ant to talk to me rather than comment on the article. So have fun
