Sport beyond Moral Good and Evil
Sport is - and should be - an amoral phenomenon (what should not be confused with an immoral one); that is, a phenomenon which is completely independent from ethics, except of, possibly, deontological ethics which concerns professionals who have professional obligations towards their employers and other persons who are provided with and influenced by their services.
Conduct according to rules of a given sport has no moral character. It has only pragmatic character, similarly as conduct in compliance with principles of the administrative code, the civil code or the penal code. Of course, when you act in accordance with rules of sports rivalry you can additionally realize also other aims - like, for example, aesthetic, spectacular or moral ones. However, in each case rules of the game and legal norms have priority, because they are the most important regulative determinant of conduct in various societies, including variously defined human teams. The above mentioned legal and sports regulations are not moral norms. They can, however, influence moral behaviours if they are in conflict with the law or rules of the game.
From that viewpoint moral norms are exterritorial in their relation to assumptions and rules of a particular sport. Contestants and people responsible for them - like, for example, coaches or sports officials - as well as their employers are neither required to account for their moral beliefs, nor for their moral behaviours, if only they act in compliance with rules of sports rivalry.
