The great thinkers of the Age of Reason and the Enlightenment were scientists. Not only did many of them contribute to mathematics, physics, and physiology, but all of them were avid theorists in the sciences of human nature.
There are many humanitarian aspects of science. Not only does science help us come to a better understanding of ourselves, but it helps produce a large number of tools that have improved quality of life, including advances in agriculture, allowing this massive population of ours to feed ourselves without starving, architecture, which allows us to live comfortably (relatively), an understanding of disease that allows us to greatly reduce our risk of many of the diseases that have been plaguing is for millennia, and so on.
It is because of the service to the population that I suggest properly treating the average person as a stakeholder. Preprint Reforming Science
I think however, we can even extend this idea of humanitarian aspect beyond humanity. We can use science to improve quality of life for other potential people (non human people may very well exist on Earth) as well, and also reduce our impact on various species on Earth.
science does not have humanitarian aspects because science is only the search for truth and, through the achievement of pieces of truth, gives man a growing power over the world, on the environment that surrounds man. This power some can even use it against humans
