Many (not all) of the greatest scientific discoveries found till this day have been discovered under unethical methods or proceedings. Unfortunately, many as well have been discovered through unethical experimentations for research purposes. However, now there are associations dedicated to approve scientific research ideas before they undergo proceedings of the scientific method in order to prevent more unethical research being done. Within the science community, we are greatful for what we've come to know... however, greatly disappointed with how many of those discoveries came about. Therefore, thanks to these associations, there should be no more unethical practices, experimentations, or research (although there are still quite a few going on in the world). That being said, yes... I believe scientists should definitely be ethical with their work. Otherwise, there will be consequences they shall face.
