Happy she found happiness in the end as it seemed she was never loved by anyone. I believe she and Ray were a toxic couple and both were abusive, but it didn't have to end in murder. Sad about her kids going to live with her parents (who berated her for dating "n-word") although the kids said they were well cared for by the grandparents, and then they went on to experience more violence, abuse, and substance abuse as adults, just like their parents, from joining the marines.
She shouldn't have taken the second shot though so I agree with the guilty SDM verdict, but I don't agree with the lengthy sentence.
