How so? We are executing someone who is so evil, that they essentially forfeit their life. They don't DESERVE to live after murdering a whole family or so. The only justice for the ultimate crime is the ultimate punishment. It does cost more to put someone to death (lawyer / court fees) than to keep 'em alive, but so what? True justice is not always cost-effective.

As I said before - if they made jails especially for these idiots, where they DON'T get 3 big meals a day, gyms to help them beat up prison guards, and they DO have to do hard labor, THEN I would be opposed to the death penalty, since that would be worse than death. Might even cut down on the murders committed.

And yes, there is another thread like this.
