So, there you go...this info was released last night. By all means this doesn't excuse anything, but rather gives us a clearer motive of what happened in the mind of this killer...
There's still a bunch of coulda-shoulda-woulda questions that come after I saw this (like, why weren't the weapons secured before informing the kid he was about to be committed?), but hindsight is always 20/20.
A particular passage in Matthew 18 continues to come to mind in the wake of this horrific event:
Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven. And whoso shall receive one such little child in my name receiveth me. But whoso shall offend one of these little ones which believe in me, it were better for him that a millstone were hanged about his neck, and that he were drowned in the depth of the sea.
