Should Child Protective Services take baby away from mother if she is making jokes about sacrificing it?

If both parents have a history of violence towards humans and animals, criminal records, mental illness and drug abuse/rehab/halfway house, why does CPS let them keep their infant? If these messages were shown in court or a CPS investigation, what would allow Sarah Autumn Beal aka Serah Sbizzle to keep the baby?
