The father should NOT be the blame for the mother's action, she is the one who killed those girls not the father and it really doesn't matter if the father pushed her buttons too far ...she knew what she was doing wrong and obviouly she doesn't care about her daugthers' and it obviously doesn't show a mother's love for them either and If a mother wants to protect her girls, she should have thought of doing the right thing by seeking the police or go thru the court system but killing them don't make it right...
And it did not say anything about the father kept pushing the mother's button, all it say that the father tried to take his daugs, but that's the mother's word against his, he hasn't spoke his side of the story yet, there's always two side of every stories and I care less what the mother say since she is the one who murdered those girls and she thinks she did this to protect them, how is she protecting them? she is the one who harm them not the father...
