If India had no rules, what would happen?
Same as any other place had no rules.
Humans are actually a vile and uncivilized lot , who have been trained to live according to some codes of conduct in the fear of shame , loss of respect ,and fear of being prosecuted with regard to the Indian penal code.
Take out the rules, and there would be absolute anarchy, mayhem, chaos.
Practically there will always be rule. Who so ever is powerful will make rules according to them and others can't decline his/her wish.
And India will be little bit different as people today in power, possess money exploit others without any fear of law. But if Judiciary system is removed even middle class will follow same rules. There will always be a person on top may be angel or devil depending upon the citizens living there.
