There is nothing more difficult than to give a precise description of the ethics of any particular set of people or of any given organisation.
Generally speaking, " ethics " may be said to deal with the morals, duty, and conduct of human beings. But man, being the complex character he is, holds such diverse opinions that unanimity on any named subject, be it moral or otherwise, is hard to find.
A standard can be attained only through the overwhelming mass of public opinion, and the standard of to-day may on the morrow be regarded as folly.
