"The right not to kill easily surpasses the historical foundations offered by the Court in Roe and Lawrence. Roe and Lawrence concerned practices that were illegal for most of the nation’s history, and were not expressly protected in law until the recent past. Yet both were deemed sufficient for substantive due process protection. In contrast, the right not to kill has enjoyed broad legal protection, across a variety of different contexts and times. Simply put, if Roe and Lawrence pass the historical foundations test, the right not to kill does so with flying colors."
