Yeah but I doubt it caused him to do this.
Like most kids I suffered concussions as a child and I never had any desire to kill doctors and their families. Turn a couple of them upside down and shake until answers fell out, yes, but not kill them.
Murder suicides are generally people who are upset that there are happy normal people in the world. And they must be punished.
I agree. The question was asked, and I had seen the information. That was all.
