As a Catholic, you can have two views on capital punishment. You can think, let Caesar do what Caesar needs to do, and the law says you can impose capital punishment, so you impose it. You can [also] be a Catholic who says we can't kill, we can't kill babies and we can't kill adults. If you let a decision be driven by your personal views, then you are not doing what a judge needs to do, which is enforce the laws of the society that you are in. But you can control your own behavior, and that is the choice that the church and God gives us - what kind of people are we going to be.
