If you aren't an idiot, the difference is perfectly clear. The death penalty is for the guilty, not the innocent. Only a deeply evil person reverses that equation.
I would rather trust God to administer the ultimate punishment. But what do I know? I'm just a freal'in idiot. BTW, how many people over the last five years or so have been released from prison after DNA testing established that the jury who convicted the person had erred?
