Here's the thing though. If a human being, was mentally and emotionally able to to torture and assault numerous innocent newborn babies, secretly and repeatedly, all while pretending everything was normal, life was good----what kind of human are they?
I think that means they have no compassion, no feelings, no conscience, no humanity, no shame, no love, no shred of decency---they would have to be total sociopaths, psychopaths, totally heartless and cruel.
So in my mind, she does fit the mood of a female serial killer. Truly one of the worst humans of all time, imo.
Newborn babies are the most vulnerable, most innocent beings in the human kingdom. Only the biggest most vile COWARDS would kill random newborns for a thrill.
