I think you're on the right track, but the part you're missing is that they don't just use kids for fucking.
They need kids to kill in order to traumatize and therefore facilitate the programming of other kids. The kids that 'survive' grow into adults, and are strategically placed in positions of power, or used for other purposes.
Q posted once about what is an Asset.
To them, programmed humans are assets.
I don't think Rachel Chandler is a bimbo, or an idiot. She's one of them. She doesn't think for herself. I would bet the Chandlers are a satanic family.
I think something we are missing behind the scenes is that Q team has managed to either 1) get the program codes, or 2) de-program victims.
