This is BS.
excuse, the language.
Sciences do deal with morals, but not those in Natural Sciences (eg physics, chemistry, Earth science, astronomy & life sciences (or any biology related disciplines)), which are only concerned with studies of nature.
The study of morals is called Ethics, and Ethics falls under the Social Sciences.
Ethics overlap with other Social Sciences disciplines, such as Sociology, Anthropology, Cultural Studies, Law (eg legal ethics), Political Sciences (eg political ethics), and many others.
Natural Sciences have different scopes to sciences in Social Sciences.
For you to say that science don’t deal with morals, is wrong…you are looking at the wrong science.
