Because it was supposed to fulfill all of Voldemort's wishes, and as Wormtail was in debt to Harry Dumbledore explained at the end of POA), he couldn't kill him, so the hand strangled him as he was forced to be momentarily unfaithful to Voldemort!
Pettigrew attempted to strangle Harry, but momentarily slackened his grip when Harry reminded him of his life debt, and was killed for it by the silver hand made for him by Voldemort. Hermione learned about his death after the battle.
Though Wormtail didn't receive a proper final scene in the films, his demise in the books occurred when he was planning to do good on his "life debt" to Harry. Wormtail's magical hand turned on him, wrapped around his neck, and took his life.
Harry then reminded him that he owed him a life debt after saving him from being killed by Lupin and Sirius (back in Harry Potter and the Prisoner of Azkaban), and after a brief moment of mercy and hesitation, Wormtail's silver hand turned to him and strangled him to death.
However, Harry reminded Pettigrew of saving his life four years ago, and Pettigrew released Harry in an unintended and momentary show of mercy. After Pettigrew tried unsuccessfully to undo that moment of weakness, the hand recognised Pettigrew as unfaithful to the Dark Lord and began strangling him.
Known life debts In his fifth year James saved Severus Snape from a near-fatal prank that Sirius Black played on him, which involved luring Snape to the Shrieking Shack where Remus Lupin was in his werewolf form. As such, Snape owed James a life debt, although they hated each other.

Peter Pettigrew got into Gryffindor, even though he was a coward, because he valued the traits of courage and chivalry. He wasn't courageous or chivalrous, though, but he valued those traits and wanted to be like the big boys he admired. Plus, it helped that one could (in actuality), choose.
However, the three Marauders did love Peter as a friend and brother, which made the eventual betrayal of James especially bitter. Pettigrew defected from the Order of the Phoenix and betrayed his closest friends to Lord Voldemort when his life was threatened, showing selfishness and disloyalty at the core of his being.

In the first part of the film adaptation of Harry Potter and the Deathly Hallows, Pettigrew never repaid his life debt, as he was knocked out by Dobby instead of strangling Harry, thus he never released him on an impulse of mercy.
Pettigrew defected from the Order of the Phoenix and betrayed his closest friends to Lord Voldemort when his life was threatened, showing selfishness and disloyalty at the core of his being. Even Voldemort viewed him with disdain, the only reason why he kept him alive was because he occasionally proved to be useful.
Fenrir GreybackRemus was turned by Fenrir Greyback, who sought revenge on his father for his unkind words about the werewolf community. The attack took place just before his fifth birthday, and although Lyall burst in and saved his son from death, the attack left Remus as a werewolf himself.
