Assassin vs. better assassin, you mean. That's one of Kai Leng's character-defining moments for me, and not one that reflects well on him: he was stopped from killing his target by a guy with a debilitating terminal illness. Granted Thane has devoted pretty much his whole life to being an assassin, but being in the final stages Kepral's Syndrome should still be a pretty big handicap. Whether or not it was intended this way, it demonstrated to me that Leng was *not* a force to be reckoned with.
