Ethics can be described as some rules which help humans to differentiate the right and wrong. Ethics in science teach us to remain honest in all scientific practices. The methods and process used should be ethical.
Without ethics, science would be a disaster. Scientists would have easily marketed the clones of humans in the market making science miserable. Without ethics, scientists might have killed a wide number of organisms just to gain results for their experiments.
Hence, ethics and science go hand in hand for making this field a valuable aspect for humans.
