Yes (You're awesome)
No (I'm a whimp)
Don't really know? (State why)
Just my opinion being totted here, but quite frankly, i'm already tiring of the whole "[u]Chosen One[/u]" philosophy in video games now. I just quite frankly want to join the ranks of the Fallen, Vex, Cabal or Hive somewhere along the line, and lay waste to the guardians. Be Brave? More like Take No Prisoners. Your opinions? Are you a goody-two shoe? Or do you have a sense of freedom?
It is a good idea but you can't exactly hold the power of light when working for the darkness, can you. Unless the darkness (presuming it is a thing similar to the traveler) sends out ghosts to bring the evil back to life, I don't see how it's possible unless you are a vex, cabal, hive or fallen.
