It is truly a quite difficult task to find the exact definition of what ethics is. People’s understanding of what is right and what is wrong differs, and the notion of ethics depends on people’s views and opinions as well. But it would be wrong to define ethics as something that people feel they can do because it is right for them.
People’s understanding of it may be deviated, moreover people cannot judge every situation with a clear head and do it objectively. Some people define ethics as a type of behavior that is acceptable by a society. However that is also not true. The society consists of separate individuals, and they may also have various points of view concerning what ethics is. We can also remember facts from history of the humanity where societies were deceived by the state, and the latter used propaganda in order to create public mood that could be used for state’s own purposes.
