@Rick D, You are right, we do have an incredibly rare opportunity here - the people can and should have strong input to the behavior of Government, and its limitations. But at the same time, it is important that we establish a general (not necessarily enforced) moral code for people - if not just for something to advise that we teach our children.
This isn't like other countries. We have a long term goal of peace and prosperity of all humanity and it will go a long way if we can establish the public opinion of morality now and watch it change over time as some challenges are resolved and new ones arise.
This could highlight points where government and civilian morals can intersect. Remember - we expect that one day this nation will survive in the harshness of outer space. If we say the preservation of human life is to be a priority, and you are to receive a signal from a manned satellite that has had some kind of failure resulting in the loss of crew. You are the only satellite/ship in range that can divert course or shift out of your orbital path in time to save the crew, but the diversion and return to your current orbital range and positioning is a costly yet necessary operation for your livelihood. Saving the crew would preserve human life, but could cost you a years profit, which then could result in depression and poverty for yourself and family. What if we decided now that we took a note of the laws of robotics here: Asgardians should not harm other humans, or through inaction, allow other humans come to harm - so long as interceding does not have a notable negative impact on the Asgardian. By this standard, our friends on the satellite are still dead. But what if we agreed the government would reimburse those would intercede where the reach of government officials or rescue parties was not convenient or even viable? I'm not saying the government should then foot the bill for every disparity used to preserve human life, but I definitely wouldn't oppose testing the idea pending economic status as it would help remove some of the blurred lines and tough decisions that can cause hesitation or refusal to act.
It's also worth noting that we should reach early agreements on certain issues that could lead to instability in the long term. For example, the issue of homosexuality is still cause for major unrest on Earth. If we are going to be a progressive nation, we should teach that homosexuality is OK, and frowning upon it is considered immoral. Reasonably, you could state that to argue anything is immoral, you should state that it has a negative impact on your feelings and provide a valid and understandable reason as to why. For the most part, people should not have the right to make decisions for other people unless they can substantially argue a negative impact. Straight people shouldn't be able to stop consenting parties being married on the basis that "they don't like it". If we raise future Asgardians to be tolerant of this, then it will become a non issue in a few generations.
Looking at issues such as extraterrestrial life, which at the moment is a non issue and given likely distances to any race that resembles civilization or intelligence it is likely to remain a non issue until the Sun goes Red Giant or Andromeda collides with the Milky way. But we don't know it won't be an issue. Probability doesn't always favor the likely. Historically, humans don't like what is different to them. It may be hundreds of thousands of years before we meet an alien civilization - if ever. But the fact of the matter is it could happen one day. And if Asgardians are raised to be accepting of all creatures great and small, and any and all intelligence that may or may not exist, we stand a greater chance of avoiding an interstellar war.
I think it's fair to say we should at least discuss a moral code, and while not necessarily putting in place we could collect data on it. Going back to a previous example, we could say "tolerate homosexuality" (along with many other ethical statements) and simply have Asgardians decide in an app whether they agree or disagree. We could publicly display the percentage of Asgardia that agrees alongside those who don't. We could take a moral code survey once a year and watch the morals of the nation shift, ask ourselves why? What are we doing right? What are we doing wrong? What are the people likely to want as a response?
We are a nation built on science. We believe in cause and effect, and we believe in studying that relationship for the good of humanity. At the very least, we need to do things differently to Earth. Every citizen needs to contribute and work as a team to get this whole thing off the ground (heh heh... puns...), in every conveniently and non-invasive method possible. And we should start trying to get it right from the start.
