Frances, I want to tell you that I appreciate the respectful conversation.  I know that matters such as these involve deeply held beliefs, and the fact that we don't agree does not in any way reflect any sort of animosity.  I have a lot to say on the subject, which will take more than one post, so I will add them in order.

Post 1:
You say you side with God.  Yet the teaching of the Church, found in the writings of the Doctors of the Church (Aquinas, Liguori and others), the catechism of the Council of Trent, and papal bulls and encyclicals throughout the ages, is that Capital Punishment is not only just and moral, but that it is the duty of the state to enact where crimes warrant it.
