This case followed closely on one in Minnesota, where Matthew Niedere murdered his parents. He was enrolled in a private Christian school, and he actually recruited two other guys to assist in the crime whom he met at that religious school and another he had attended. Supposedly his biggest argument with his parents concerned his choice of churches. It's really hard to see festering evil like this, I think, but the rest of us want to know how such a thing could happen when parents try hard to do everything right.
I wonder why life is perceived as so cheap?
No, I don't.
One of the best Christian movies I ever saw was Hard Core starring George C. Scott as the Calvinist father who thought he was doing everything right. The theologically astute will recognize it as a remake of the "prodigal son" tale, with a nod to all five points of TULIP calvinism. Parenting can be a white-knuckle ride at times, and it is only God's grace, not our controls, that eventually leads to successful outcomes.
