I would hold people accountable for being in an creating a corrupt leaders rather than the leaders themself.
You should know that there are some countries that the people cannot decide who will be their leader, because the people in charge of the government ha e made life miserable for the citizens, by putting them in a poverty level. This is done in other for them to make the people not have that power to go against their will. If you talk against the government, you get killed.
No matter what the people do, to vote out these bad leaders, it will be in vain because they have corrupt people like them that should be able to challenge them or put a stop to their evil intentions, but these people will even support them, because everyone is after their pockets.
