PS. And might I add that my own view on execution is 100% consistent with that of the Catholic Church.
For the record, I don't agree with Catholic Church teachings on this matter. I am more into old testament "justice," and retribution, and balancing the scales. I favor the death penalty, even if it is not a deterrent; indeed, that would be my view, even if it were not a deterrent if the executions were far swifter than they are now, the delays attending which may enervate the deterrent effect. That is just my personal point of view.
I never said it was inconsistent with the Church because you certainly have a right to oppose the death penalty. However, here's what then Cardinal Ratzinger said in a memo about denying communion to pro-abortion politicians to US bishops during the 2004 presidential campaign.
"Not all moral issues have the same moral weight as abortion and euthanasia ... There may be a legitimate diversity of opinion even among Catholics about waging war and applying the death penalty, but not however with regard to abortion and euthanasia."
This statement carries weight because Ratzinger is now Pope Benedict XVI.
