I actually oppose the death penalty as a matter of principle. But to me, if you're going to have it, this would be one instance where it should be used. I'm not sure I understand how it's not "cruel and unusual" if someone kills an adult in a rage, but if they rape a child, now it meets the standard for "cruel and unusual" just because they didn't kill the person whose life they ruined.
Maybe it's because I'm not a lawyer...
