If Russell was part of a polygamy cult, they would take a page out of ancient cultures' books and castrate him, then keep him around as the eunuch who tended to the women.
Or maybe they wouldn't even castrate him, since there would be no chance of any of the women wanting to copulate with him, physically capable or not.
Well, no, they wouldn't have castrated him, because none of the LDS-offshoot polygamy cults actually do/did that. As for the women, they tend to themselves (and the children), because those cults aren't royal harems where the women are idle; they're doing all of the domestic labor and child-rearing that would have been handed off to servants in the kinds of environments where eunuchs were created and used. And those women don't need eunuchs around to police the
shit out of each other--snitching on your sister wife who expresses dissatisfaction, or another girl who acts just a bit too familiar with the wrong boy, is a way to gain favor and exact revenge.
Honestly, had Russell been born into such a cult, I think he would have met with some fatal "accident," if not in infancy, then at least once it became apparent that he wasn't going to amount to much. A community that is willing to expel able-bodied boys and young men who are capable of making real contributions to the community's welfare isn't going to get all tender-hearted over someone like Russell, who is a liability.
And in societies that did practice castration, Russell wouldn't have lived long enough to become a eunuch. Either he would have been exposed or suffocated at birth, or he would have died of slow starvation (because Moebius babies can't latch on to a breast to nurse). But even had he survived, he would have been unlikely to have been made a eunuch because he just wouldn't have been worth the effort. He would have ended up doing low-status, low-skill, low-paid work, as he could get it, and perhaps alternating that with beggary, all while remaining unmarried, being the butt of constant, open ridicule and physical abuse, and not having the means to hire prostitutes (who would reject him, anyway).
