It isn't a matter of making the perpetrator the victim.
It's just that I can imagine a number of scenarios that might have led to the outcome in the news story, and none of them require the demonisation, or dehumanisation of the woman involved.
That the child died is a tragedy, but attempting depict the mother as some kind of lower life form is unhelpful and extraordinarily shortsighted.
It's the sort of knee jerk reactionism that allows everyone else to absolve themselves of guilt, safe in the knowledge that 'normal' people wouldn't ever sink to such depths.
But shit happens, and it can happen to anyone.
