Trivia: The line "come with me if you wanna live" is said by Sarah Connor for the first time in the franchise.
Trivia: It took 12 months to digitally alter bodybuilder Brett Azar into a young Arnold Schwarzenegger in 35 scenes, which accounts for less than 5 minutes of screen time.
Chosen answer: As long as Skynet kept sending other Terminators into the past to kill John Connor before he became the leader of the human resistance, it was necessary to keep sending reprogrammed Terminators into the past as well so that the timeline would not be altered, thus resulting in a Skynet victory. While it is possible that John and the resistance may have used reprogrammed Terminators to help them in the future, this was never depicted or otherwise mentioned within the film series.
