Samurai were the military nobility, and ninja were covert agents and mercenaries. Neither were one organized group of mercenaries, but were classes that served under the many feudal warlords (daimyo) in Japan. It would be impossible for all ninjas to be Assassins and al samurai to be Templars. Assassins and Templars could be ninja or samurai, but not all of them could be either group.
