I agree with Kallera, and although we never met Fray, we know Fray was definitely a good guy. He died trying to protect the kid (I don't remember names very well...), and that's sacrificing himself for love. We didn't meet him, but he existed and was seemingly one of the nicest Guys we met. Yet he knew Much about darkness.


Yet, you're right, we learn many things by ourselves. But that's not negative at all. It's more dangerous because, like Sid was going to do, we can isolate ourselves in a passion such as Hate.... But ultimately, darkness is neutral. It can achieve a greater good through love or terrible deeds through hate. Ultimately, Darkness is the power to achieve one's dream, and protect the individuals.

And on PlDs, it's highly theoric. Maybe I'm wrong, but the crystal's nature seems to enforce my interpretation. Each Crystal is charged with the light successive PLDs obtained, and we can see that charge as a physical one : A mere number. Therefore, when your crystal gains power from another... Aether does not create himself, it obeys to law, and there's probably, like a mass conservation law, a Aether Conservation Law. The light aether you obtain needs to come from somewhere, and the only known recipient to Light Aether is PLDs' crystals. So necessarily, you devour their aether.

The loser can still build back his aether (following the ACL, he probably converted it from elemental aether, day after day, fight after fight), but he loses a part of his power anyway. Oathkeeper seems not to react to the value or individual strenth of its bearer, but the ligh aether's PLD's crystal's charge of its bearer. So you can become the wielder of Oathkeeper by yourself, but the fastest way is acquiring power through duels. You can disagree, it's a theory, but it seems the more convincing for me... And then, ultimately, PLD's power is the power to achieve a greater good, to protect humanity, even if That means destroying some men.

So yeah, DRK and PLD are opposed, and I don't say one is better, in a matter of values, than the other. I say That Darkness is based on individuals, while Light is based on collectivity.
