It's altruistic to want to be an agent of healing in the world, still believing that change can happen. There is an assumption that the world changes, and if you follow the world's thinking then this is the conclusion you get. Jesus addresses "The Golden Rule" in ACIM where he says that "doing unto others..." is still dependent on your perception of yourself and of others. Right perception must be a result of healing the perception that one is having. Attack is impossible in corrected perception.
