The point of time loop is that it is a LOOP. It has beginning, no middle, and no end. It just is. That means that every point in time within that loop are all happening at the same time. Cid is a super telekinetic 10 year old freak, who watches as his mother gets shot and killed by a Looper. Cid escapes to grow up with a chip on his shoulder and anger and vengeance in his heart (think Anakin Skywalker) and uses his powers for evil, becoming the Rainmaker, taking over the world, and killing all the Loopers. While the Rainmaker's men are arresting Joe the Looper, they accidentally kill his wife. Joe then overpowers his captors and goes back in time to kill Cid as a child before he can become the Rainmaker.Once iIn the past Joe hunts down and finds Cid, who will one day become the Rainmaker. But while shooting at Cid, Joe accidently shoots and kills Cid's mother, Sara. Cid escapes, with a chip on his shoulder and anger and vengeance in his heart. He uses his powers for eveil taking over the world, and hunting down the Loopers. Joe's wife gets killed, Joe goes back in time to stop Cid from becoming the Rainmaker, but kills Cid's mother instead, which in turn cause Cid to become the Rainmaker, hunt down Loopers, kill Joe's wife, etc etc etc. But along comes Joe's younger self who realizes that it is the death of his mother that causes Cid to become evil. So young Joe kills himself, meaning that older Joe never existed in the future, never had a wife to get killed, never came back in time and killed Sara, meaning that Cid never became the Rainmaker.
