The Volturi don't keep Demetri around because he's a great fighter. I mean... he IS a great fighter, but they keep him because he's the best vampire tracker in existence. Jasper probably could defeat Demetri. But who knows?? Demetri has had much more experience than Jasper... and the vision in the movie wasn't in the books... and should have been impossible since Alice can't read futures of hybrids and shapeshifters. The fight scene in the movie is just a bunch of bunk! It NEVER happened. The Volturi DO keep Felix around because he's SOO strong. Jasper would not be able to overpower Felix. It just can't happen. The only other vampire who could possibly defeat Felix would be Emmett... and even his chances would be unlikely.
