That's not the point at all. The dying people described here were just more honest in their last moments. The lady who couldn't have one friend among her family because of her wealth, the old bitter man who couldn't process losing his wife - they suffered for decades. Possibly because of their own decisions. They did not have some bad last minutes, they had some bad last decades, and then minutes of reckoning.
