I know it is hard to understand opinions very different from the PC norm.  You miss the point completely about mitigating the murder.  Murder is the most heinous crime that exists.  Far worse than anything else (IMHO).  So what am I trying to say.  Nothing can excuse the murder, but the factors that preceded it can definitely provide insight as to behavior patterns that should be avoided if murders are to be avoided.  Do you want to end such murders or not.  Forget nonsense like who is to blame.  Do you want to eliminate the murders???  If you do, you must examine the pathway that led to the tragedy.  Unfortunately, lots of woman can't do that today because to them it implies responsibility which is unacceptable.  Recently, I raised the mulcher affixed to my skid steer on my farm.  On a hill.  To my surprise, I quickly found myself trapped in the machine rolling down the long hill.  If I had not raised the mulcher, the machine would not be a shambles.  So hard to see cause and effect?
