Death Penalty

http://pewforum.org/death-penalty/
Why there is such dissension among religious people on the topic of capital punishment is very understandable, becuase there are many different ways you look at it and many different ways to support both sides of the issue religiously. It says here that more white Protestans (80%) than white Catholics (66%) favor capital punishment for adults, but there is no gap when it comes to minors- 38% of white Protestants and 39% of white Catholics are in favor of it for minors. I don't really understand why this is... obviously I understand why the percentages would go down for minors, but in terms of adults, I do not understand why less Catholics than Protestants are in favor of it. Catholics tend to be more "traditional," and maybe when looking at Bible passages with traditional meaning they find more reasons to be against it? I just thought it was interesting that there was such a gap between the two sects of Christianity becuase the core values in both are the same as far as I know.
