What's the difference?

Light and Darkness, Order and Chaos, Good and Evil, all these things we perceive to be two separate things. But the truth is without one we cannot have the other. You would not fully understand peace if you never heard of war, you would never think of things as evil if you never knew what good was, and you would never have known sight through darkness if not for the light. Some of us are more prone for darker things, more animalistic tendencies, we rebel against the norm of being all goody goody and do no harm to others, we fight for blood and love it. We are those with a darker shadow than others, we try to blend in even when we know it's futile. We give into our baser instincts and we feel emotions in a more raw manner. Some of us try to stand out and give into the instincts more often, while others only use them for, well for lack of a better term, more noble reasons. Those of us like that walk the line between it all, we use our animal sides for strength and our human side to better blend in. Now don't get me wrong I'm not saying we think we are part animal, but more in touch with our wild sides, our instincts, the things that drive us forward aren't always from our human side, the logic side, the side helping me type this out. Basically all I'm trying to say is there is two sides to everyone, when you get down to the core, not Good and Evil, Right and Wrong, Light and Darkness, but logic and emotion. Some of us just give in to one more than the other, does that make us evil or dark, depends on how you look at...
