As a society, we should place our trust in institutions and processes and not in morally fit people.
Why? well, good people are hard to come by. India could produce only one Gandhi, America had one Lincoln and the world had just one Mother Teresa.
Even if they do come, like all humans they too are prone to errors and eventually fade away.
However, institutions can withstand the winds of wickedness and sands of time for a long time.
We created one United nations and did much good work than any mortal man. We prevented world wars, famines, human rights violations, and countless war crimes and yeah, it still stands tall despite a few shortcomings.
Hence, it’s wise and prudent to build institutions rather than wait for exemplary beings.
