The entire premise of a balance is that one cannot exist without the other. Without light, there is no darkness, and without darkness, there is no light. When Ninjago was created, the darkness came with it. Every time the Overlord was defeated, the balance was restored. Darkness was never destroyed. Evil has continued to natively exist in Ninjago.
