Any organisation, system or country, there is a need for an independent body to act as checks and balances. Without the existence of such a body, it is foolhardy to expect man to check himself.
Leaving man alone to his own device, his ego and arrogance will lead him to his own destruction. Without God, madness will triumph over all man.
That is why they said 'the world will go round and round' or history will keep repeating itself.
