You have an inbuilt goodness. Why should you allow some poisonous elements to destroy that goodness? Protect your goodness by any means. Stay away from the toxic people.
Corruption is the abuse of power and position. Corrupts have bad habits and values. Become rigid and don't pay any bribe. If it is require to complain at the appropriate level, do that.
Corrupts are in complete greed of money. They have no compassion for the fellow citizens. We all need to fight against this evil to eradicate corruption completely from this nation.
