There is enormous attention paid to the crimes of advanced sociopaths (which is good).
But this is where sociopaths are born, and grow up.
I think the boys who did this should be horsewhipped.
Not because it would delight me (it would), but because it MIGHT make it possible that the course of their character development that led them to this place could be interrupted.
And it might make it possible for the other childen to grow up believeing that justice can be done.
