To abide by law and to violate law,both the instincts are inherent in man.
If the laws are reasonable,( both rigour-wise as well volume wise) ,majority of people may follow them.
Too many or too rigorous laws create hostility and repulsion.
To every action there is an equal and opposite reaction.
Excessive, rigorous and harsh  laws do not command any regard or fear.
They generate reverse feeling.
If one feels that he cannot follow  majority of the laws relevant for him or some particular law to the full extent then a tendency develops of not following any law or the particular law to any extent.
Legislate some more laws without caring for the implementation of existing laws and you create more illegal acts.
Human nature requires regulation but resists control. Controls kill responsibilities.
Let us have faith and trust in ourselves.Let the people discover and develop the confidence in themselves.
