I think Michael Corleone really had it in mind to get rid of Fat Clemenza by making him go up all those stairs. Clemenza's blood type was Ragu by then.
Fun fact the scene in Star Wars where Anakin kills the separatists while the emperor forms the new empire is a homage to this scene. Also shoutout to the stuntman who rolled down the stairs, hope he got paid extra for that.
