Angie replies:

In the SS, LV tells Harry:  "I killed your father first, and he put 
up a courageous fight . . . but your mother needn't have died . . . 
she was trying to protect you."

This sounds like LV  had no intention of killing her, until she 
interfered which, of course, sounds very un-Voldemortish to me.  If 
he planned to kill her, why tell her to stand aside -- why not just 
zap her, the way he instructed Wormtail to kill Cedric?

I mean, this was IT for LV.  I don't see why he would hesitate at 
all.  Killing Harry was much more important than killing Cedric.  Why 
even waste time to say, "Stand aside."?  By the time he said that, 
she would have been dead if he had zapped her.
