Question

Is there any difference between doing what is morally right and doing what will make one happy?

Answer 1

MORALLY RIGHT
The term moral correction or morally right is something which can be seen as the synonym of what is correct according to law and rules i.e. when something is ethical and follows rules and regulations. It is not important that the condition which is morally correct may same time bring happiness for everyone. Because every individual is different from other so what one thing makes one happy may bring grief for others. One does one's duty when one acts according to the moral rules. The main idea behind morality is confirming to the rules. Morality is concerned with identifying and obeying rules. It is right to obey the rules and wrong to disobey them. Anything can be regarded as right or wrong on the basis that to what extent it conforms to the moral rules.
HAPPY
Happiness is state of mind in which person is both mentally and emotionally stable. In Greek happiness refers to the good life, or flourishing. According to Aristotle, Pleasure is not a good in itself, he argued, since it is by its nature incomplete. But worthwhile activities are often associated with their own distinctive pleasures. Hence, we are rightly guided in life by our natural preference for engaging in pleasant activities rather than in unpleasant ones. According to him, virtue can lead to true happiness. Happiness is achieving what we desire leading a good and normal life in which what one aspires can achieve it, so Aristotle also argued that happiness is achieved through good life and good life comes when a person is rationally active.
So when we are talking about morally right things it is not necessary that it will also account for happiness for everyone.
