PS. And it's worth noting that I oppose capital punishment, so it would hardly upset me if Alito were to emerge as an opponent of the death penalty. My views on both abortion and the death penalty are almost entirely consistent with the Catholic Church, more so than that of many American Catholics, and I'm not merely a lapsed Catholic, I'm a collapsed Catholic. LOL
It should upset you if you're a consistent conservative. The Constitution clearly provides for capital punishment. Any decision to the contrary -- whether based on changing societal values, norms of international law or religious beliefs -- simply constitutes a justice substituting his view of what constitutes "good" for the clear guidance of our adopted Constitution. If a justice wants to say the death penalty is unconstitutional, he should have run for elective office.
Of what you as an analytic tool is the "Catholic" adherent paradigm on anything? The usefulness of the tool seems to have achieved the null set as far as this near atheistic Wasp can tell.
