Portrait of Antonin Scalia Antonin Scalia Stanford v. Kentucky — Opinion of the Court

It is, to begin with, absurd to think that one must be mature enough to drive carefully, to drink responsibly, or to vote intelligently, in order to be mature enough to understand that murdering another human being is profoundly wrong, and to conform one's conduct to that most minimal of all civilized standards. But even if the requisite degrees of maturity were comparable, the age statutes in question would still not be relevant.

Portrait of Antonin Scalia Antonin Scalia Stanford v. Kentucky — Opinion of the Court

It seems to us, however, that while the number of those jurisdictions bears upon the question whether there is a consensus against capital punishment altogether, it is quite irrelevant to the specific inquiry in this case: whether there is a settled consensus in favor of punishing offenders under 18 differently from those over 18 insofar as capital punishment is concerned. The dissent's position is rather like discerning a national consensus that wagering on cockfights is inhumane by counting within that consensus those States that bar all wagering.
