Actually I don't think the question is entirely applicable to the DP.
IF this man broke into your home and you were alone there with your sleeping child, would you let him walk out the door with your child or would you kill him? No middle choices. He is GOING to walk out with the child unless he is dead - kill him or not?
This question is very applicable to the tenet of:
"All life is sacred, I would never kill anyone for any reason."
However, in regards to the Death Penalty, I don't think it is valid.
The question posits a "battlefield" decision, a "heat of combat" response. It is no different than asking a cop if he would shoot an armed robber, or a self-defense scenario.
These scenarios are emotionally charged, life-or-death situations where fear, adrenaline, anger and nerve influence your decision.
These are "hot" scenarios.
The Death Penalty is very, very different.
In an execution, there is no imminent danger. The defendant is essentially helpless. The psychological factors are different but just as strong. The massive machine of justice, the state is focused on one person. That person is going to die, pitifully, possibly painfully. They are alone, strapped into some device, in a cold, harsh room.
Added to that, is our fear of Death. Everyone fears death to some extent. Deep down inside, everyone imagines themselves in that position and it is truly a horrible one. We are all going to die, sometime, somewhere, and no one wants to die alone and afraid.
The Death Penalty is a "cold" scenario.
It is one thing to kill a man in the heat of battle. There is no time to think. It's do or die.
It is an entirely different thing to calmly and calculatedly activate a device and end a man's life. Both the condemned and those involved with the execution have days, weeks or even months to think about it.

That being said, I'd like to reiterate my stance. I support the Death Penalty. I think it should be administered across the board, regardless of race, religion or social status.
The Death Penalty should apply for crimes from murder, (1st and 2nd degree) some types of rape and child molestation. Any crime comitted with a gun should be elligible for the death penalty. (The logic being that if you pull a gun, you mean to kill someone.)
Ideally I think the condemned should be executed no later than 1 year after being sentenced.
The preferred method of execution should be hanging. The British calculated exact tables involving weight, age, etc. When used properly the chance of a botched execution is fairly small.
"Cruel and Unusual Punishment" does not, in any way, imply or guarantee a pain-free execution.
Hang 'em high.
