Well not to be totally heartless (And don't take too much into this) but parenting is a bit subjective, based on religion, background, herritage, living conditions, etc. and what one person might considered bad parenting, it goes both ways in the fact that you or someone else might be doing something they may consider as bad parenting.
Abusive/Neglectful is a given for all situations, I'm just focusing on the term "Bad Parenting" or "Good Parents" as it was put.
It is, but in this case no one could say they weren't bad parents. They just weren't abusive enough or neglectful enough for DCFS to take the kids away. They'll just monitor them instead to make sure they didn't wind up dead or really sick for the next year or so.
