That was actually a very inspiring story, about two people who took a child who everyone, including her own mother, said would never rise from a near comatose state. Compared to other severe deprivation cases, Dani's story is a legitimate miracle. Those first 5 years are impossibly and astoundingly crucial for development, physically, morally, and intelligence-wise. Having a child come far enough to understand right and wrong and begin to take care of themselves is amazing. I think Bernie and Diane are two of the most caring and blessed individuals I've ever heard of.
Also, I'm gonna refrain from passing judgment on the original mother because I think she's one of the few people who are simply too stupid to be hated. Like the author of the article stated, she seems like a person who can't or won't take any kind of responsibility for her actions nor for her own well-being, instead relying on outside events to intervene and force her to act. Just seeing the state of her house, she doesn't even care enough to try to improve her own situation by killing the pests or fixing the damages. Ironically, I think she may have also been neglected as a child, though not nearly as severely as Dani, because most moral and ethical development comes from the parents, and the mother's pattern of latching onto new boyfriends confirms that she has a fear of being alone.
