There are statistics gathered on this kind of thing . Child murders don ' t often go unreported . So no , it is not more common than I think . It is exactly as common as I think . And what you are trying to say is that the whole reason men don ' t seek custody as often is because the mothers would kill the children if they did . That is just patently false . You are trying to paint the average woman as evil . But the average mother would never harm her children . This is the work of a mentallyunstable woman and , as truly awful as it is , it is NOT a common occurrence . Does it happen ? Well clearly . But fathers kill their children over divorce too and I wouldn ' t dream of claiming that it is a common thing for them to do .
