Well, my role is to balance the two. Not within other soul but to mine. Evil in a sense that one can't be as perfect as our Creator and His son, everyone makes a mistake for once in their lifetime. Evil in a sense that makes us human a human being, a rational one, so one possesses the right will but still bears the evil will. And thus help us human distinguished what's right from wrong. And if I can balance myself, so as with my relationship with other people including you. ;)
