I completely understand the point of your post and I admire your knowledge and skills, practical skills that should be taught in school, to all of us (as I think we should be taught in school many other important things for our lives). At the same time, I am amazed at the local traditions, and if we are going to compare Nigeria with Bulgaria again - no, we diverge on this point. In Bulgaria, people turn to doctors, of course, when they can afford it financially. But now I think of that case of my GP who died last year while still of working age and her colleagues said that if she was lucky enough to be driven to the next big city where there were really good doctors she would have been saved. But unfortunately she was taken to another city where there are not very good doctors. I.e. the problem here is that the doctors are not good, so even if you turn to a doctor in such a situation, the odds are not entirely on your side.
On the other hand, however, every incident has its rational and its irrational side. When a man dies in such an absurd manner as the actor you speak of, I have nothing else to say except that it was fate. And what if those superstitious and not so educated people around you are talking about, maybe felt it, because educated people, those who have knowledge and believe science unconditionally, sometimes lose touch with other forces that are rather felt, than are understood. They may have felt that this was the fate of this person and therefore nothing could be done. 🤔
This is just some guesswork, just to ease your frustration. 🙃
