Neither side justifies murder. You're just altering your definition of murder to allow for it to cover that. Both sides agree that an unlawful killing is wrong, both sides also agree but there are some circumstances when unfortunately is necessary to kill another person but that's not the same as murder.

For example some people do say that Obama killing Bin Laden was murder. But I think that most people would define it is an act of defense of the nation. It's not like he didn't do anything or that he could be arrested and brought to court

And yes it is getting to the point where we no longer live in a free and just society. Which is a major problem. But worse it divides the people to the point where it's no longer possible to get back to a free and just society. Which is an even bigger problem

And yes I can't argue with you, that is what we're seeing today. America is fracturing into smaller groups who become tribal and defend their interests rather than have open and intelligent conversations looking for common ground

Perhaps it's inevitable. I mean every major empire eventually falls and very frequently if you look at it the declines that we're seeing today mirror many of the declines of empires of the past. People breaking into factions, no common sense of right or wrong, no common ground for discussions.

I guess we'll see where we go from here
