The Shichibukai system has been created by the World Government in order to help rebalance the balance of powers in the world that was threatened by the Emperors and their crews and to give very powerful allies to the Marines.
Of course this objective was far from reached in reality as all the Warlords had no real loyalty to the WG, more or less all followed their own interests with Jinbei and Kuma being the only ones who did follow non-selfish goals, and with all of them having defied the WG to various degrees.
But which one was the closest to do what the Governement expected of them ? Which one did really the worst job as a warlord ? What is the order of the warlords when it comes to be doing the warlord job and follow the Government's orders and expectations ?
