**2. Overview of ethics**

Ethics is a concept in the field of philosophy. The word ethics is derived from the Greek word 'Ethnos' which means character, customs and habits. It is closely linked to the word 'moral' which is derived from the Latin word 'Mos' (mores) but they are different. Both ethics and morals generally mean the customs and socially accepted norms. Ethics is a branch of philosophy and includes the values, guidelines, rules and regulations and the justification for these values, and guidelines [6, 7]. Hence ethics is required in our daily lives in making choices from various available options and alternatives [8]. Ethics guides various professions in carrying out their duties while morals have to do with the way of life. Ethics is concerned in the concept of right and wrong. This was first conceptualized and structured by many Greek scholars and established by Aristotle by the third century BC. Various factors have affected the concept hence it has evolved over many centuries. It is the systematical philosophical study of morality. Ethics guides human beings where they are as it is the set of principles and values governing a group or even an individual. It also extends to the consequences of wrong misdoings. The application of values and moral to human activities also constitute ethics [9]. The conduct of right and wrong are both related to ethics and morals. The principles developed by an individual regarding what is perceived as right or wrong are morals. Morality can sometimes transform to cultural and regional norms while ethics is not affected by societal, cultural or religious norms. The standard of conduct which guides and governs an occupation or profession is knowns as professional ethics. Ethics is connected to the code of conduct, it guides how employees and employers to conduct themselves at the workplace. The understanding of moral values is related to ethics hence the relationship between ethics and morals [10]. Ethics is widespread in all areas of life as decision making is a part of life [11].
