I just want to say one thing - do you know what the meaning of the image of the YIN YANG is (it's a circle with two commas, one black and one white, with dots of the opposite color in them)? The meaning is: in everything dark (evil), you can always find at least a drop of light (good), and in everything light (good), there is always a drop of darkness (evil)! I think I answered the question of the topic...
Where do we end up when we save the world?
