Justice Roberts here says out loud the real problem with "living constitutions" -- the fact that a new set of justices can change laws that have been on the books for centuries, just because they feel like it. A law should mean what it says, and we should change it by actually changing the law, not pretending its words now mean something else.
It's clear Dahlia hates this notion of reversing course, but ignoring it does her no credit. Its quite clear the Framers were more or less just fine with the death penalty, and perhaps other nastiness we'd rather not think about -- things we have passed laws against.
We know she hates the death penalty, and I'm no fan of it anymore myself, but to pretend that it has suddenly become unconstitutional on its face is simply ludicrous. Either pass a new amendment (an admittedly slow and messy, but ultimately more democratic process) or get all fifty states to do away with executions, while hoping the SCOTUS will chip away at the more egregious practices of the "machinery of death".
