And by the way, my family is originally from PA and I visited Lancaster and the "Amish country" just about every year until I was 14. I've also bought and had furniture made by them and have had dealings with them. So, I am familiar with them. I feel terrible for these people. But I feel terrible for any child who witnesses such evil, Amish or not.
You are right, no child should witness such evil. May God bless and give strength these victimized children, their families, and their community. And may God also be gracious to this monster's own innocent children and family, who will carry the burden of his horrible and cowardly act for the rest of their days.
