The problem is without shared values, you can't define "bad" at a national level. Both sides believe they are on the "right side of history", that's the problem here. The "greater good" is "political" in nature, but it's not something that's hyper-partisan like what we seeing occur in the nation. We need a minimum set of neutral rules in nation with a very very wide variety of beliefs to maintain our technological nation. You can and should think of the greater good in terms of Maslow's Hierarchy of Needs at population level. If you don't have food to eat and energy to keep you warm, self actualization or individuality really don't matter.
