Sally did kill her husband so the title is accurate. How and why she killed him is the debate of the series. By the end it seems the filmmakers took her side which is fair but in the end nobody won regardless of who was right. In my opinion she had one fight too many and killed him to end it once and for all. The 'if I can't have you nobody can' may play a part but the element of PTSD in battered women was the main cause. Even if I don't find Sally as innocent as she makes herself appear I don't believe she deserved to spend as long as she did in prison for it. At least she's out now and can make up for the time taken away from her.
