If you don't think you are supposed to defend your wife and children from murders then I suggest that you discuss that view with your wife and get her opinion as to whether she expects you to defend her and her children from thugs.
And your views are between you and God as are mine.
I believe it is my responsibility to defend the defenseless to the extent of my ability to do so even if it might result in my death. I believe that is the ultimate act of love.
Jhn 15:13 Greater love has no one than this, than to lay down one's life for his friends.
