Why is it important for citizens to fulfill the obligations and responsibilities of citizenship?

It is important because citizens ultimately form the society they live in.

Explanation:

The citizen are more important than the government for their own country as they are the ones that truly form the society of the country in which the government they choose is allowed to operate.

Thus their own obligations and responsibilities are a huge part of successful citizenship in a successful country.

For a country to flourish its people have to work towards making it flourish too and not be detrimental to the process of progress.
