Interesting topic. Ill admit my own view is somewhere between understanding the necessity for our own morals and laws and at the same time knowing that they only work because we want them to.
I dont know if creatures besides humans, (and maybe intelligent ones like dolphins), can really have an idea about morality. For most animals life and death are just things that happen, I dont believe they attach anything to them and the same goes for theirs and other creatures actions.
Then of course as others have said; natural disasters, regardless of scale, do not care who they hurt or what happens to others, since there is likely no consciousness to guide it.
However in the context of humanity, I believe the very makeup of our minds lends us towards the formation of moral values. Always being the social, group, creatures that we are means that it is part of our survival. It might be seen as not intrinsic since it is often a case of social osmosis that teaches us such values growing up, but to me I see the cultivating of moral values within human groupings as something inevitable, of course the interesting part is whether or not those morals are good or bad depending upon who is viewing them at the time and how their own moral opinions have been formed.
Of course this could also be interesting from the side of objective vs subjective. Objectively it seems better to protect the group as a whole, sometimes this might lead into ostracisation or even killing of those who were previously part of the group so as to benefit the rest. Subjectively it is better to protect individuals and then lead that into a view of the whole using the subtleties of a situation. For a subjective viewpoint, cutting someone off or down would not always be neccessary for the benefit of the group and may over time, hurt it.
In any case, as I said before, interesting topic.
