The basic set-up of Terminator, in theory, creates two paradoxes. When the T-800 (Arnold Schwarzenegger) is sent back in time to terminate Sarah Connor (Linda Hamilton) before she can give birth to future Resistance leader John Connor, the AI that controls him, Skynet clearly feels this is a solid plan. But, in sending the T-800 back, Skynet also causes the Resistance to send a human agent back, Kyle Reese (Michael Biehn), who becomes John Connor’s father in the past. So Skynet messed up: Had they not sent the T-800 back in time, they wouldn’t have ever created their own, enemy, right?
