Why are conservatives so opposed to abortion but so supportive of the death penalty?
Probably because the fetus didn't commit pre-medidated murder.
You know, forcibly closing the door on all possible future hope of redemption in this world by killing somebody really doesn't carry the same moral character or significance that people inflamed with blood-lust seem to think that it does.
My feeling on this (for the 1000th time) is that the death penalty is the price society has determined will be paid for certain acts of pre-meditated murder and I agree that should be the price. I want anyone sentenced to that to have DNA tests if DNA was a part of establishing their guilt and subsequent sentence, assuming such testing wasn't used initially. Executing someone who has even the slightest possibility of being innocent is unacceptable, and although there probably is no 100% certainty that will never happen, we need to be as diligent as possible in ensuring it doesn't.
I reject your characterization of blood lust, though you're not the first, or last, to make it.
