In India, it’s important for a guy to get married and have a male heir. I mean, really important. So important, in fact, that he could suffer eternal consequences if he doesn’t.
The key thing is that the male heir performs a key role in the burial ritual, and a guy who doesn’t have a son risks not having someone to perform the ritual properly. Such a person comes back as a Gayal and attacks the males of his family for failing to perform their duties. He can also attack other males in the area.
