If it really is a disease and people are powerless over it then I object to people being prosecuted for driving under the influence of alcohol and other drugs. It's not their fault.
We had two murderers here years ago who were high at the time of the crime. They robbed and shot a School Principal outside his office when he was working late one night. Both received a death sentence. The Supreme Court overturned the sentences because the jury wasn't instructed to take intoxication into account as a mitigating factor.
They were again sentenced to death at retrial. I think both have been executed. As far as I'm concerned they should have hanged after the first trial. Drunk or sober when you do something like that you are a waste of oxygen. Regardless of my opinion that is the law in death penalty cases, I don't know about other crimes.
