OOP: Life Debt?

[Barclay, Maggie]

No: HPFGUIDX 66750

I've been spending time this morning (when I should have been working)
wondering why Sirius had to die.  Sirius could have stayed home as he was
asked, but he chose to go to the Ministry.  I know that is in his character,
but I think he might have been slightly more willing to stay and play
messenger if Harry had not been one of the people in danger.  If Harry
hadn't been one of those in danger, Sirius's motivation in going would have
been adventure and a sense of doing something valuable for the Order.  But
since Harry was in danger, Sirius's motivation was to protect Harry.  So
Sirius died to protect Harry.  Sound familiar?  

Also, so much was going on in that room, how do we know that Sirius didn't,
I don't know, step between Bellatrix and Harry as she yelled "Avada
Kedavra"?  That would make the life debt even more evident.  

MaggieB--who is hoping Sirius's death meant something, and that the
whimpering Peter Pettigrew finds out that his master can't kill Harry
because the friend he wasn't willing to die for died for Harry
