The order have been working really hard to ensure that the human race have as many opportunities as possible to redeem themselves in this world. There are thousands of people who have tried to bring humanity to a higher level, but unfortunately for those thousands, there are millions who only care for power and have no interest in progress and the future of their species.
There is no question at this point that this is the thing that the order hates the most about humans. There are no plans to allow humans to gain full control of planet Earth for this reason. If the order was not here to keep humans from destroying everything, the world would have been destroyed a long time ago. Humans are too greedy and to hungry for power and that is their biggest flaw.
