But of course if Snape hadn't taken that vow he could have turned his 
wand onto the Death Eaters instead of Dumbledore. It all goes back to 
that vow. Your central problem is explaining why a good Snape would 
make that crazy vow; and whatever the explanation you come up with it 
needs to be HUGE to justify such bizarre behavior. Saying it's good PR 
and might help Snape advance in the Voldemort organization in the 
coming years just doesn't cut it, and Snape being dazzled by 
Bellatrix's beauty is even worse.

It makes me wonder if Draco isn't somehow critical to the taking down 
of LV. I am a firm "Snape's good" believer, so I've been tossing 
around an idea that Draco plays some major part in the downfall of LV, 
either helping Harry or undoing LV in someway that helps Harry. 
Everything Snape and DD did in HBP was to save the lives Harry AND 
Draco. Part of me thinks this is just because Draco is a kid and DD 
wanted him to CHOOSE the white hats, but another part of me wonders if 
there isn't some other reason that Draco needs to live.
