My brain made me do it?

Good article over at CNN about how brain differences that correlate with psychopathic behavior can be seen in children as young as three.

The article gives me hope, but as usual, the comments do not:

I swear I didnt kill that person.. My brain made me do it...

Ah, snideness. The easiest way to bury your head in the sand while trying to look clever.

Then there's no way that you can be rehabilitated. We'll have to remove you from society....permanently.

Armchair neurology: if it's in your brain, then there's no way to change it! And then a scary threat... punctuated by a scary... ellipsis.

There was, however, one comment that I am glad to have read:

I know I'm one of these people. My lack of guilt and fear of consequences have led me to make some huge mistakes. I've had to work very, very hard to make some major changes in the way I live my life and make decisions. This is a very interesting study. I hope that good things come from it.

What do you know? Sociopaths are people too! Of all the things I'm glad for, high on the list should be my acute sense of guilt, remorse, shame, and the host of other social emotions that keep me both from causing harm and being vilified.

Do you punish your child differently depending on how intentional you deem his act to be? Would you label him a monster if you were to learn that you passed on genes that made it painfully difficult for him to act in accordance with most of society? Or would you do your damnedest to make sure he stops hurting himself and other people?
