I would think that scientists are bound by an ethical code of conduct to consider the impact of their work before proceeding with it. I think of the scientists who helped develop the atomic bomb as an example. The standard telling of this narrative is that they were completely zealous in the development of this device towards many ends. They saw it as a means to end the war, or to end war, in general, as a source of limitless power, as well as a means to engage in a scientific impossibility of splitting the atom. Yet, I think that all of the scientists involved understood that there was a need to talk, to discuss realities that would arise from their experiments and discoveries. Such a moment demonstrated that while science is a boon in so many ways, it also involves a level of ethical and personal responsibility that requires discussion and discourse before proceeding with any new endeavor.
