I was pretty sure you were going to come back with the idea that man has not evolved in any capacity to make better moral choices.  It's the favored fall back position.  It's not true.  Humanity is using a more evolved process in making moral decisions.  Might no longer is the absolute arbiter of right.  If that were still true, the US would be the undisputed global dictator strictly on the basis of it's nuclear capability.  That is not how the globe or the US operates.  No one has dropped nukes since 1945.  The UN's existence is another example of how humanity has evolved in it's understanding of itself.  Are there still some backward areas where tribalism is the end all and be all?  Yes, unfortunately, and too many nations in the Western bloc are now being challenged to make a decision: do we continue to move forward for the benefit of all or do we regress into nationalism and tribalism?  Francis has it right, the future is about unity while appreciating diversity.
