there is a difference between science, as in "understanding nature" and technology, which is about exploiting that knowledge for building something useful. Knowing everything about the atom is harmless, using that knowledge to build an horrendous weapon is evil.

Also, knowing everything about the atom does not affect our behavior, except through technology. Social sciences are more problematic though because they are about us, as part of nature sure, but in the social context we live, which can be affected by what we know about it. So proper considerations must be made when designing the research questions and methods, and when discussing the results.
