What is the significance of the Continental's strict 'no killing on Continental grounds' policy?

The Continental's 'no killing on Continental grounds' policy is a central aspect of the world building in the John Wick film franchise. The Continental is a luxury hotel that serves as a safe haven for assassins. The hotel's management enforces a strict code of conduct that prohibits any violence on the premises. This means that no assassinations or attacks can be carried out within the hotel's walls.

The significance of this policy is that it creates a sense of order and structure within the assassin underworld. By providing a neutral ground where assassins can conduct business without fear of violence, the Continental allows for a level of professionalism that would otherwise be impossible. It also establishes a sense of honor among assassins who abide by the rules and shows that there is a level of respect among these dangerous individuals.
