“This girl’s condition obviously hindered that process and it’s likely that the lack of seratonin and oxycontin did inhibit bonding. The mother isn’t really at fault for failing to produce the typical mammalian response.”
And? Does that excuse holding a kid at a distance and verbally and emotionally abusing ehr own daughter?
We aren't perfect. I can't blame the woman for being unable to get closer to her daughter. What you perceive as a moral failing, I perceive as just one example of human frailty out of billions of possible examples. It's something of a sad story, although with an apparently happy ending. However, I can't fault the mother for failing to mimic biological reactions that in her case never occurred.
There are countless that are not good parents to a child or all of their children. At least this person seems to have come to some awarness, recognition and honesty about that failing. She isn’t due applause, but she is a long way from condemnation.
