Fear of God will control sin
It is true that a few people exploited the concept of God for personal benefits. But, based on the few exceptions, you should not remove the basic system itself. A few railway accidents happen and due to such accidents, you should not cancel all the trains. You should concentrate to avoid the accidents. Similarly, some students might have copied in the examinations. Try to catch, such students. But, do not remove the system of examination itself. The system serves majority, doing lot of good. You forget the vast positive side of the system based on the minor negative side. The concept of God controls the sin in the society. If the concept of God is removed, lot of people will do lot of sins since already the ways to escape the punishment in courts are already available. The society will be crushed into pieces in the absence of the fear for sin. If God disappears, the hell disappears subsequently.
The concept of sin will drown and destroy the society like a Tsunami. However, this does not mean that the concept of God is again a created view only to save the society. Such conclusions are not correct. The concept of God is basically true and we have explained the positive side of such concept. It is a real concept and hence, the positive side is also real. Of course, the minor negative side is also real and control should be implemented to check-up such negative exploitations.
