Ethics is a branch of philosophy interested in the description of the fundamental standards and significance through which the actions of human beings can be considered right or wrong. Ethics is normally divided into; descriptive morality, applied ethics, and moral philosophy. Descriptive morality refers to the definite customs beliefs, principles and people’s way of life. In other words, it can be stated that descriptive ethics explains the behavior of a given people. It includes research from most Social Sciences as a section of the course of identifying what people do or their beliefs about morals. Applied ethics deals with debatable moral concerns, for example, punishment, civil disorder, pre-marital sex, animal rights and abortion. It has been recently split into categories such as business ethics, medical ethics, sexual ethics, and environment ethics. For applied ethics to be implemented, the issue at hand should be controversial in that there are those who are supporting it, and there are those that are opposing it. For example, the issue of gun ownership is an applied ethical issue because there are those for and against it. This paper will look at the subdivisions of ethical system(s) and an explanation of how to abide by the ethical dedication.
