I would hold people accountable for being in a creating a corrupt leaders rather than the leaders themself.
You may be saddened by the nature of global leadership, but I respectfully disagree that the people only should be held accountable for producing a bad and corrupt leader in the nation. Many people are uninterested in political power, and they are powerless to do anything if political leaders want it. Standing firm on their mandate may cost them their lives, if not more. Corrupt leaders are always the most powerful in politics, and their success and power stem from arrogance and corruption. They are the most difficult to fight with unless you have a strong person who can stand for the people and be the voice of the people with some strong political power.
