We are all responsible for our own duality and depending on another to balance us out is codependency. We can strive for wholeness, which is what most of my personal blogs have been about, and if we gain wholeness we can balance with another whole individual and amplify each other along our paths. In theory we could choose a destructive path together, but I can't imagine any whole individual would seek pain and sorrow. Everyone has their own path though, so who knows.
