The "Martians" will be a happier lot, better educated with a whole different perspective on life. The Earth needs a lifeboat out there, and IMO it should be Mars, ASAP.
If and when the happier, better educated "Martian" population grows to become thousands or millions of people after a few generations, surely they will continue to "all get along" forever without any need for armed conflict, because of their different perspective on life.
Or, we Christians can just wait a few years to become citizens of heaven the natural way.
