There are alot of ways to kill jedis. You can knock him off an edge,knock him down and then shoot him with a vehicle,run him over with a speeder bike,lure him near the worm on tattoine so the worm pulls him in,land a plane on top of him,lead him into the place where you are leaving the battlefield and make him die, etc. Tell me if this information is useful.
you can also kill him with the vangaurd.make him chase you. drop a mine infront of him.
