> Can a doctor test drugs in mouses? (Why you excluded bacteria from your list?)

Bacteria is included into a "living being", but anyway. I definitely do not pretend to present a well thought oath in the comment yet. But seems The Hippocratic Oath is a good precedent. Probably, it's better to compose such ethical principles for each activity, because there are different fallacies and temptations for different professions. And there is a separate set of temptations for a common human. We teach and study natural sciences, but we don't teach ethics and philosophy in popular nowadays STEM curricula.
