I really don't get you stance. Of course, you can make more fine-grained distinctions and that's fine. You can claim that medical doctors act as medical scientists when they conduct studies and as doctors (consultants) in their practice with patients. But that doesn't mean the value judgments aren't part of the science.
If a seismologist has evidence that an earthquake is likely to occur in a certain area, should they not warn the public about it? I would say they clearly should, and any other view about this seems bizarre to me. I find it equally implausible to not call a seismologist who warns about an impending earthquake a scientist. They're a geophysicist or geologist. Or take an astronomer warning about a possible collision of a meteor with Earth -- astronomy is a science, so why would that person not be called a scientist?
There is a an array of scientific disciplines for whom consulting (in your sense of the word) is a frequent, though not primary part of their activity, and we certainly still call them scientists. Material science, vulcanology, epidemiology, seismology, meteorology, biology, climate science, economics,... basically any science that involves the study of processes that might have important consequences for mankind.
