Like I've said Vader kills slowly with the froce choke because the nature of the Sith, He's punishing those who fail him, and quickly snapping there neck doesn't send the same message to the officers as somone slowly sufficating.. Vader has shown far more powerful version of force choke as well where he simply crushes his opponent's entire chest, instant death. In The Force Unleashed, Vader hold's Kento Marek up in the air choking him while interigating him, the only reason it wasn't an instant kill was he wanted information, but the second he wants to kill him he broke his neck.
