I wonder about that stuff too, but only as much as sanity permits. Madness lies in that direction.

The most disturbing practice I've heard of, coming from the reports of generational Satanists, is where women bear and raise children specifically for sacrifice. I'm not talking about some sort of slavery/forced breeding scenario, it's voluntary.

Try to get into that headspace. You can't. It's so far beyond the pale of anything a normal person would understand as human morality it simply cannot be conceptualized. So underground human livestock farms? Regrettably, I don't doubt it for a second.
