The Assassins were supposed to protect the Prince, not steal his crown. If you're a fan of courtly intrigues, or at least courtly intrigue as a metaphor for franchise evolution, I recommend reading up on Prince of Persia: Assassin, a Sands of Time spin-off that was in pre-production at Ubisoft Montreal across 2003 and 2004. Eschewing the storybook morality of its predecessor, the game would have cast the player as a hooded bodyguard armed with pop-out wristblades and a repertoire of vicious grappling moves, escorting an AI-controlled princeling through Jerusalem. This bloodthirsty mixture had promise, but was seen as too severe a departure for the franchise, so Ubisoft greenlit Assassin as a new IP. Thus the seed that produced the 70 million-selling Assassin's Creed series - and through Assassin's Creed, the open world action-adventure genre of the present day.
