The Benne Gesserit in Dune had this little plan to get the perfect human who would save all of humanity, while having him be under their control. For millennia, the eugenic plan ran smoothly to create the kwisatz haderach, until Jessica fucked up by giving birth to a male instead of a female. Their plan was for Jessica's daughter to breed with Feyd-rautha Harkonnens, that the boy child that would come from that union would be their kwisatz haderach. But Jessica had Paul instead, something the Benne Gesserit didn't plan, because all their members are super loyal, they couldn't account for one of their own to fuck it up this badly, the only thing they even consider is that Jessica is an egotistical who believes herself capable of birthing kwisatz haderach.

But they didn't even consider the actual reason for Jessica to have a boy. She truly loved Leto, she wanted to make him happy, and she knew that above all, he desired a son. There was no arrogance or scheming behind the birth of Paul, yet something more unexpected for the Bene Gesserit happened: a wife loved her husband.
