Unfortunately the media let out just enough information for people like you, who have obviously not lived with alcoholism and in domestic violence and are completely uneducated about both, to reply to this tragedy as simply as "Everyone have choices...She could have left the marriage long time ago...(improper grammar by the way)."
If you knew anything about the subject you'd realize that yes, almost every time a woman kills a man in a domestic situation, it is because she feared for her life because they do fear for their life and are about to be killed themselves.
My family has lived in total "hell" with an alcoholic and physically and emotionally abusive husband and father for 41 years. We, the four dauthers, have witnessed the abuse and been involved in the abuse. However, we loved our father and we love our mother and guess what? Our mother loved her husband! She did get help at various points in her life but HE didn't and wouldn't because he wouldn't even admit he had a problem. Alcoholism is a disease, just like drug addiction.
We have always and will always be around for our mother though we are adults and married, with our own children. We couldn't be there 24 hours a day. This tragic event occurred as my father planned it-when it was just the two of them and their beloved dog in the house.
I hope you make it a point to do a little research on alcoholism and domestic violence in an effort to educate yourself and those around you that are experiencing this because I guarantee you there is someone close to you who lives in the same "hell" as my family.
Everyone have choices. I am not saying what the deceased did was right but, we all have choices. She could have left the marriage long time ago. What is sad to me is "almost" every time a woman kills a man in a domestic situation the reasoning is "she feared for her life".... this seem to be excuses and/or copycat killers. Again, she like "most women" have choices to leave before the situation esculates
Where were/are all these so-called friends and family members when this "abused" woman needed them. Nowhere to be found. But, as soon as tragedy strikes... they all appear, and have voices. Just like our government... nothing is never done until it is to late.
