Warning: This one is a real downer.
I am a Catholic, and my Church speaks out against the Death Penalty. I am proud to be a Catholic because of that stand. I have said my peace on this before, that I see the Church as a moral compass within world. That compass can help us learn the right ways to live. But their view of the world is a utopian one, and I'll say again that we don't live anywhere near "Perfect."
This is why there is a duality in being both an American and a Catholic, and why we must have a seperation of government and Church. Sometimes, what we do can not line up with what we believe.
The only acceptable number of Death Penalties is zero, but because stuff like this happens, that zero number will always be a goal and not a reality. This man and this woman are the reasons I believe we must always have that option on the table. Society must sometimes take lives, in spite of our desire to give a chance at redemption. Sometimes the nature of the crime makes the criminals un-redeemable: not to God, but to Man. We may not judge their souls, but their crimes and their bodies fall within our jurisdiciton.
Even if they are crazy.
To quote Ron White: "[they] should have eaten crayons and rolled their s*** into little balls; the penalty is much less severe."
Sometimes it can't be about rehabilitation or witnessing, it must be about Justice for the dead, and the protection of the living.
