"Kiddie fiddler uncle/neighbor/cub scout leader molests young boys...at adolescence young boys start molesting little brother/sister/neighbor kid..."
This is a story as old as the hills, and as predictable. The sad thing is when we catch it, that we don't lock up the adult offenders (and some of the juvenile offenders depending on the severity)forever. And so the cycle continues. We know when we release these people that they are broken beyond fixing, and yet release them anyway knowing that they will, sooner or later, destroy another child's life.
Matthew 18 is for those who believe the "Christian" way to treat predatory criminals is with lax penalties.
"6But if anyone causes one of these little ones who believe in me to sin, it would be better for him to have a large millstone hung around his neck and to be drowned in the depths of the sea.
7"Woe to the world because of the things that cause people to sin! Such things must come, but woe to the man through whom they come! 8If your hand or your foot causes you to sin, cut it off and throw it away. It is better for you to enter life maimed or crippled than to have two hands or two feet and be thrown into eternal fire. 9And if your eye causes you to sin, gouge it out and throw it away. It is better for you to enter life with one eye than to have two eyes and be thrown into the fire of hell."
