Maybe you know the type. Alpha male overachievers whose mission in life is to reproduce. They only need money to play the game, and they only play the game to get the money to play the game. You know, the “play to spray” guys.

Play to spray the DNA. In any way.

Everything else you try to project onto Joseph doesn’t stick because he couldn’t operate outside of that realm. It was only by the grace of God, Dr Bennett, and a lot of long suffering saints that none of his little bastards made it.

Or, maybe the whole polygamy thing was a way to hide his ED.
Look at everything else he achieved in life- all of his successes were made by other people's work. So get polygamy going under his guidance and everyone will think he's the Alpha Bonerman. I'm sure he took women to bed, but how do we know he didn't blame them for his performance issues? Everyone thinks they are keeping one kind of secret, but it is a different secret. Meanwhile, it works out beneficially for both parties.
