If he wouldn't let them act in motherly roles, say if any of the other male characters fathered children, would Carver let them play a role in their children's lives or try to keep them away from their kids? What about mothers, would he let them raise their own kids? (I mean, for characters besides Rebecca and Alvin because we all know how that turned out.) Is there a specific child-raising process he has planned out for future generations? Would there ever be a 'school' and how would it be run?
Yeah, he’d let parents raise their own children. It’s easiest, for one. Breaking up families would cause way too much tension and disloyalty among the flock, for another.
Carver only barges into the parent/child relationship when he feels there’s a need, like what happened with Carlos and Sarah. He felt Carlos was sheltering her too much and doing her harm, so he intervened.
(I imagine what we saw in EP3 was plan A: realign Carlos’s parenting style to match Carver’s. Plan B would probably be to separate them, and put Sarah in the care of a guardian who could raise her “right.”)
I don’t think he’s planned out super far in advance when it comes to future generations, though. So there’s no “master plan” for child rearing. Right now the only school to speak of is Tisha, with other people chipping in depending on their skillsets. (For example, I’ve just started in on a scene where it’s mentioned that Carver is teaching Maddie’s younger brothers how to shoot properly.) I’m not sure how he plans to expand beyond that.
