Thank you for the great response. Much appreciated.
Their belief is not inconsistent because of the role innocence plays. Now you may disregard the importance of innocence here, but that doesn't make their views inconsistent
Well, what about a significant number of people executed, which were completely innocent? There are some absolutely galling stories out there about innocents being executed despite the fact that there were huge doubts on their guilt or on the verdict as such due to the conduct of the proscutor (withholding evidence, using known liars as witnesses, relying on more than dodgy "scientific" evidence, recanting of witnesses who had a personal motive to snitch in the first place, etc).
In that view the possibility of one innocent person being killed should automatically illegitimze capitol punishment. Apparently it does not.
While I can understand the stance of the catholic church I still think that logically you cannot oppose abortion, while supporting the death penalty.
You made me understand, however, that this inconsistency is not applicable to a lot of those people. It doesn't make it logically less inconsistent in my view.
Anyway, thanks for the insight. It's at the very least, very interesting.
