We often confused ethics with moral.
Ethics is the study of what constitutes good and bad conduct, including
related action and values.
The term ethics is sometimes used synonymously with morals.
It would be more correct, to use the term morals and moral to refer to
conduct itself, and terms ethics and ethical to refer to the study of
moral conduct.
So when we used the word moral, we refer to an action or
person insofar as either is considered right or good.
When we use the word immoral, we refer to an action or person insofar as
either one is considered wrong or bad.
