This will not happen with the rules and laws that the state has made for themselves to guide and lead them in their activities as individual countries and as global entity like we have different organizations that creates higher rules that check against human degrading treatment and inhuman acts. Like the UN universal human right declaration by the general assembly. This document ensures that their is dignity to life etc. There are other charters and agreements in other organisations by member countries to ensure human rights etc. So as a country and globally, human lives will not go back to the savagery, nasty, short, brutish as Thomas Hobbes described in his book state of nature.
