I agree. Getting the knowledge out there that if you drive drunk and kill someone you will go to jail for a long time will help people with their decision making process. And I agree that understanding addiction does not remove responsibility. But many people do try to use addiction knowledge for escaping the consequences. The judge in this story didn't buy it.
Finally. And yes, I agree with the judge for the sentencing decision, but not the reasons he gave.
Now, follow me here: supposing you are an alcoholic walking around doing your alcoholic thing and decide, "This has gotten pretty old. I lost the wife, the kids, my job, all the money and they kicked me off the bowling team. I gotta quit this." Should the guy rely on will power alone or seek help through AA or the medical community?
