Morals are, as Matt said, not concrete. I believe there is also an innate difference between morals and codes of law. Laws are enacted to keep society functioning and to reduce the amount of entropy in a society (for obvious reasons). Murder causes various undesirable things to society (you lose someone who can work, people grieve which can cause them to be unproductive in the society, etc.), and so it's against the law.
The laws of science are arbitrary and relative to its constituency. They are not "the laws of science" because of its own force of authority, they're the laws simply because those are the general characteristic traits that we have been able to identify that have been produced by the select circumstances we see in our (or some other) universe.
I have major problems with this. Science and morality are very different subjects. Morality is not based on observation and data-collection, while science is. Science is true wholly because we rely on its findings being correct so that we can function on a daily basis. Morality is subject to no such scrutiny.
If science and ethics were the same, none of us would have a problem with the Zimbardo experiment, or anything else subjecting humans to "objectivity".
There cannot be moral objectivity so long as more than one human being exists. Society by its very nature rules out a natural convenient code of ethics for every person.
And what does that have to do with objective, or "concrete," morality?
Not sure what your point is here. I'm well aware that science is inextricably founded upon observations. In that sense, virtually everything we could ever consider to be "knowledge" or "fact" is relative. I'm pretty sure that's not the same sense of "relative" in which people are referring to morality here.
Morals are an invention of mankind, and they differ between social groups or individual people due to differences in values and beliefs. There's no objective measure of what is wrong or right, since everyone has different morals. Even if everyone in the world agreed on the same morals, it would just be humans sharing an opinion as there is no accurate way to determine the validity of one's moral views. Morals are just the personal beliefs and opinions of humans, whether as a group or as individuals.
Excuse me. Rome fell because of the imposition of unreasonably high moral standards in the form of Christianity. An empire forged by a bestial nature must maintain that nature to ward off external pressures. Christianity diminished the will to individualism (such as the great conquerors like Caesar and Trajan) and instilled a slave morality in its people, leaving them weak and vulnerable to barbarian invasions. They handed the reins from strong leaders to weak bishops.
The Roman Empire would have lasted much longer if it maintained "looser" moral standards, celebrating military and sexual spirit, rather than the opposite which Christianity champions.
Doesn't the validity of moral views come from the basic human desire to live free from harm and pursue one's interests? Just because morality is based upon human desires doesn't mean those desires aren't universal.
If there is a concrete morality, this is something akin to laws of nature, and must be adhered too for peaceful living. Excluding the aspect of a diety to tell us what they are, we can still find them out through trial and error.
By trying various combinations of laws based on trying to find this balance you can over time discard ones that have a negative or non-impact.
Since we have thousands of years of human history to study at this point, we should be able to quickly discard plenty of "obvious" ones. Unfortunately, people still want to do things that are damaging either to themselves (longterm) or others for (usually short-term benefit) selfish reasons.
So what a person may want to do really shouldn't play into it, but whether they would want it done to them/ be on the other "end".
Looking at things from that viewpoint can cause a lot of clarity, to an unpleasant degree for those honest with themselves.
Whether or not a pragmatic set of moral edicts can be deduced by all people has no bearing on whether not they are objective. The only way that they could be objective would be if there was a creator who placed them there, and even then I'm not sure how that standard of objectivity would even be measured outside of divine punishment. The fact of the matter is that you're speaking belligerently and without basis. You have no evidence to support the conception of a morality that is "concrete," let alone a definition of "concrete morality" and whether or not it's synonymous with "objective morality."
Scientific laws and morality are not "universal" or "relative" in the same sense as the other. A "universal" moral guideline is merely one that it has been collectively agreed upon is right, for whatever reason. A universal scientific law (well, a scientific law is universal by its nature) is one that is the only possible answer that can be derived from the given value data. There is no interpretation. The data itself provides you with the answer. This is completely unlike morality in ways that I hope I don't have to explain.

Yes, I understand that morality is subject to interpretation where science is not. But to call morality "relative" and "a matter of opinion" seems to me to indicate little more than a discomfort for using the powers of pure reason to arrive at objective knowledge. If every rational creature in the world can unequivocally agree upon certain moral views, I think there's more to those views than just collective opinion.
For someone who argues about the fact that there is a concrete morality, can we assume that your observation of the laws of nature through the thousand of years of data resulted in your belief that guns are essential for a peaceful living.
