What if Voldemort owes Lily a life debt?  And that is part of the
reason that the curse rebounded back on Voldemort.

We know that Voldemort is reluctant to kill Lily.  What if part of
that reluctance is because Voldemort owes Lily a life debt?  Just like
how Peter is reluctant of Voldemort using Harry (blood) for the
"rebirthing" potion.

Voldemort is still Tom Riddle during Lily's childhood (Pre-Hogwarts).
 It's possible that Lily "saved" Tom Riddle's life one way or another.  

The consequences of having a life debt are still unknown so far.  It's
possible that having a life debt prevents the person owing the life
debt to kill person whom he/she owes the life debt to without some
huge nasty consequences. Voldemort killed Lily, and the next spell he
(Voldemort) casts rebounds back on him. In addition, now Peter will
not be able to Harry, and now Voldemort is also unable to kill Harry,
since Voldemort now have Peter's arm.
