Yet still an accident.
There is a clear difference between intentionally abusing a child (where the child is hated and disliked by caregivers) and failing to provide a safe environment (where the child may be in an otherwise good family unit).
Don't see why you can't see the difference. It is important to differentiate between active abuse and accidents because they require different solutions.
If you take your simple approach of lumping all injuries together regardless of intent then you will fail to solve much at all.
The topic is about failure to protect our kids, most accidents are preventable, and intentional harm still falls under failure to protect.
