With respect, that is a somewhat simplistic viewpoint. I lost my father to a sudden heart attack. The problem with the 'bombing out' idea is that there suddenly a huge gap where a person used to. Now, I'm sure you're seeing from the perspective of the person who dies, nice and quick like, surely better than long and drawn out. But it's the living the suffer most from a death and being denied the opportunity to come to terms with it to some degree before it happens is very hard to deal with.
