When Billy kills himself, Carrie tells Julie that she is better off now (with Billy dead), and asks Julie "am i right?", and Julie answers her "you're right, Carrie". The character herself finally realizes that she is better off with her husband dead, even with a baby on the way. It's hard for the show or the character to be much more against abuse than recognizing that the wife is better off after the abusive husband has killed himself.
