Darkness = Bad Guys
That's enough for me
Darkness is only as evil as the person wielding it; it's all about mind over matter, though the effects of darkness can be quite lethal.
And don't come with Riku/Terra using the Darkness, since both use Darkness for their friends.
Which pretty much proves my point.
:23: Is no one taking in that it could be a spilt personality? I mean come on. MX seems very evil, yet apologizes and asks Ven to kill the darkness which was MX's mistake. Obviously, Nomura never would just have someone who is a powerful villan be evil from the start. Nomura always adds a plot twist.
I doubt he has a split personality, he could just be good at manipulating others for his own needs. Who knows at this point, but if he truly is sorry for the chaos he's wrought upon the worlds (and for what he possibly did to his apprentice (or Ven for that matter)) then I suppose you can call him a tragic villain. And obviously you're not evil from the start, HK.
