nah he missed on accident. Why would he miss on purpose and leave the persian empreror to live that makes no sense. spartans were breed to k!ll, not show mercy, or any weakness they were k!lling machines HE DID NOT KNOW HOW TO MISS. If he had k!lled XERSES there would have been no reason for another war against persia if they had no king. The whole point was that xerses was thought to be a god.... gods dont bleed. but he was aiming to k!ll.
actually..the spartan king starts showing some mercy when his captain loses his son...
and I HATE, I HATE that people keep referring to the fu*king BOOK...like if hollywood follows the book line by line.. so far, every movie that was based from a book..has been modified to fit the screen.. so that whole "xerxes DIE!!" sh*t can not be applied to the movie.
