Not really. He's incredibly mentally ill. He'd probably be heavily medicated and not even know he was in the world most of the time.
Note, I am not advocating the death penalty. I laid out in another thread why I believed that isn't much of a punishment for him either (short version: he doesn't care if he dies. He forfeited his life, either by getting shot or the death sentence afterwards, the second he made a choice to do what he did. And he knew it. The threat of death holds no punishment for him.).
And therein lies the problem: When a person is so crazy that basic humanity no longer factors into their thought processes, our concepts of punishment are rendered fully impotent. It's like Charles Manson. That dude doesn't give a **** he'll spend the rest of his life in jail. He's completely insane.
