Why does this girl not value the life of another?

I just watched a very disturbing video on the news, of two teenage girls in Missouri fighting. There were a lot of kids around them with their cameras out and videoing the action, but not in any way stepping in to help stop the fighting. The one girl who prevailed almost killed her opponent. in fact, at this writing, she is in critical condition, may have permanent brain damage, and is in real danger of dying. The girls involved were 15, and the Missouri prosecutors involved, are considering charging the one girl, as an adult, with attempted murder, or murder, if the girl dies. I listened to the talking heads saying how horrible this was, and of course, it was horrible. However, no one acknowledged the cheapening of life, that 51 years of mother’s killing the children in their wombs, and being celebrated for doing so, has had on children and adults alike. We, as a society, just don’t consider the lives of babies, children and older adults, as valued, as we once did. And unfortunately, this is the outcome. Doug
