Surely ethics is not something a person is good or bad at? Individuals who may or may not live by a certain set of 'life rules' would not even recognise these or define them as ethics. Ethical rules are different from one person to the next; from family to family and society to society. Lots of external things - families, peer groups, systems (such as capitalism), legislation, religions and life experiences may influence the development of such rules in any one individual. Also brain damage, mental illness, child abuse and substance abuse may impair (or enhance?) an individual's ability to develop such rules.
Life itself may lead individuals to change their particular ethics over time and obviously what may be 'ethical' to you may not be 'ethical' to others as people have different viewpoints and prejudices. Therefore it is quite possible to instruct people in ethics or particular sets of rules regarding right and wrong. What is far more challenging is to get people to AGREE to one set of rules (universal rights and wrongs, morals, ethics). You can also teach logic but what you cannot do is make people ACCEPT it.
If, for instance, you were to initiate a discussion around the moral issue; to kill people is wrong (which is often said to be a universal rule of ethics) before long you may discover that some people hold the view that it is wrong to kill regardless of the cirumstance; others may think it's OK to kill in self defence or to protect loved ones form harm; others may say it's ok to kill someone if they are near death and suffering; or to kill armed soldiers and so it goes on.
In the end whether or not it is right or wrong to kill another person depends on the beliefs of the individual and the particular circumstances facing them. Sometimes it will not even be a conscious decision to kill but more of a reflex action; an instinct (perhaps the human survival instinct 'kicking in' as mentioned in an earlier post).
If someone wanted to kill all living things, and destroy the universe, would you consider this ethical/rational?
It's definately irrational, and even animals would agree it's unethical. Are you saying there are no universal or cosmic codes of conduct?
