I will give her the benefit of the doubt for her actions. She was a victim of domestic abuse and she might have suffered from postnatal depression. And she showed remorse over what she had done and tried to do the right thing once she got help. I really don't see much of a double standard here - i.e. in this episode. (I'm a historian and I came across similar stories where men did the best to ditch all responsibility putting the blame on the woman, maybe that taints my vision.) In the show as a whole - that's another question that probably deserves its own thread.
