Ethics can be differentiated from Morality, as the latter is a set of beliefs and practices concerned with what is understood as good and evil. While ethics are philosophical deliberations that come up with the moral justifications and principles that guide our moral values. Thus, ethics has a wider scope than morality. However, still, the terms- ethics and morality are often used interchangeably.
While Morality can limit the scope of human deliberation, in determining the goals and means towards the human ends, Ethics lays faith in the free will of the individual, and gives enough room for the individual to deliberate upon different means to an end, while also providing a moral justification for the same. The obligatory character of ethical norms is derived from the very fact that they are derived on the basis of experience of the ages, based upon human free will.
