Mothers that actually let their partners harm their children, do they suck as mothers?

If the boyfriend or husband has already been abusive towards the child more than once and the mother is just standing there, doing nothing... do you think she sucks as a mother? I'm tired of hearing about those neglectful mothers in the news. Watching someone beating your child and doing nothing is already neglecting your child and enabling it.

As an expecting mother, I can't imagine (not even my parents... no one) watching anyone hurting my child and doing nothing. I picture myself getting in between and fighting like a pitbull till the very end (even if it meant getting hurt in the process) and getting my child to safety first.

I actually have no sympathy towards anyone that watches their child getting hurt and does nothing.

and still keeping the child in that horrible environment is neglecting their safety, the opposite of loving them.
