I do agree they indulged in what is to me sickening behavior. It is disgusting to me to think they would have sex with other partners, in front of each no less, for instance!
They were undeniably careless and made some terrible decisions i.e. leaving Danielle in the dressing room at Mervyn's.
I do think on the other hand they also had the kids involved in the normal activities kids that age are, and I don't think the kids were outright neglected.
I'm hoping they realize the sick and empty path they were on, acting on base impulses and indulging themselves as if they were still carefree teens without adult obligations.
On this, we agree. When one is in the depths of and gripped by of such a depraved habit, it is hard to climb out. I pray that they can somehow turn their lives around.
