There are numerous crucial issues related to this horrible story. Certainly this couple is highly disturbed. As a society, we do need to understand how people like this become so disturbed. Likely they were subjected to child abuse as well, though this cannot be taken as an excuse. We also need to understand what it is about our society that families like this can go unnoticed and unreported for decades. Our whole society is becoming increasingly fractured, with lip service being paid to "mental illness", but almost nothing done to prevent child abuse. Institutions, and individuals often turn a blind eye to evidence of abuse. As a society, we are all responsible for the occurrence of situations like this. All abuse of children needs to grab our attention and be stopped.
