Vader Said "If you only knew the power of the Dark Side." There may have been validity to his statement. The Sith/Dark Side fight with anger and passion. Look What happened when a Jedi "Crosses over to the Dark side temporarily": 1. Obi-Wan kills Maul after Maul kills Qui-Gon. Imagine the emotion and agner of loosing a mentor and a friend. 2. Anakin kills Dooku kills after Dooku injurs Obi-Wan. He was very angery and passionate (just look at his face.) 3. Luke cuts off Vader's arm after hearing that Vader knows Leia is his sister. You may say that Anakin lost to Obi-Wan when he was angery. But at that point he is already a Sith at this point. So he does not Apply. Agree or Disagree?
