Tobyfoot23:

I also think that Harry had to believe that he was going to die for the 
cause (all of his friends and everyone not a DE).  His sacrifice 
mirrored his mother's sacrifice and that "old magic" was then invoked 
for everyone he cared about.

Paraphrased from DH:  Harry says to Voldy, "Didn't you notice that your 
curses aren't sticking to anyone you put them on?"

If Harry hadn't believed that he wouldn't survive the encounter with 
Voldy, he wouldn't have accidentally protected everyone on his side.  
Granted this only worked on Voldy and not his DE's, but it was some 
protection none the less.
