Politicians are required to lead the members of society.
Legally speaking, Yes. But in humanitarian nature, We don't.
They are representatives selected by us in the government or opposition.
This only works in Democratic Government by which Citizens has the right to choose their leaders.
There should be some interface between democracy and people. So they fill the gap. WE need men and women who will work out of a good heart intending to make a good impact in our society one that really make sense and make us inspire to follow their written laws and policies
Actually, We don't really need these politicians. If you heard the song Imagine by John Lennon, We don't need leaders if we can work as one and if we only tend to be united and at peace. No race, no countries, no religions, and etc.
and make us better citizen.
We don't need laws to be a better citizen, We could be better if we choose to be better. We can be successful if we choose to be successful. What I'm saying is that We all have the rights to choose for ourselves and no one should be an influence for that change.
