Why would the children be punished for the father's mistake? Do you realize the kind of trauma they must have experienced all their life? Imagine everyone thinking of you as a freak! And the wife too must have suffered immensely bringing up children that society saw as freaks. If that's the law of nature then nature needs therapy.
If nature was so upset over the accidental death of the snake then the father should have turned into a Ramsay Brothers type monster (with snake-like characteristics).

Plus it was a genuine mistake: he is described as a kind-hearted and pious man who was very concerned for his pregnant wife and in his hurry to get back to her, he made a miscalculation, a mistake that is all. He did not knowingly kill the snake in cold-blood. Why should he be punished for this and not just him but his innocent wife and children...for a lifetime?!

Once again, if this is nature's law then I think nature itself has gone psycho!

I think it's some kind of a genetic disorder. The rest of the story is probably just a coincidence or fiction made up over time.
