1. Cindy is right.
Is it really possible that Snape's loyalty to Dumbledore is a sham? 
Well, 
he's apparently a spy. He must be able to dissemble. Did he (as I 
asked once 
before) therefore recruit Pettigrew? Has he been preserving Harry to 
use his 
blood in that restorative potion when the time was right? <snip>

2. Voldemort *believes* that Snape is his Faithful Servant, but is 
actually 
wrong. <snip>

3. Voldemort is actually referring to Crouch/Moody. <snip>


Now me:
I would like to add a #4 (actually, this is my husband's theory, 
which he completely, 100%, believes in):

4.  Snape is Ever So Evil but NOT a faithful DE

According to this theory, Snape has Evil Overlord ambitions of his 
own.  He is keeping Harry alive because he knows Harry's Big Bangy 
Secret (whatever that may be), the secret that means that Harry has 
the best chance of anyone to defeat Voldemort.  

Snape's hatred of Harry doesn't have anything to do with LOLLIPOPS 
(too soft for a guy like Snape, in my husband's opinion.)  Nope, 
Snape resents Harry because he has to keep him alive.  Because for 
whatever reason, Harry can do what Snape himself can't (defeat 
Voldemort).

Then, of course, there will then be a scene in book #7, after Harry 
defeats V, in which Snape turns and thanks Harry for ridding the 
world of Voldemort
 now no-one stands in the way! (followed by evil 
laughter, general shock, and Ron—if still alive—making I-told-you-so 
comments)

My husband came up with this before finishing GOF.  When he was done, 
I asked: don't you think that's too similar to Crouch/Moody helping 
Harry, then showing his true colors?  Surely JKR won't do that 
again?  He answered that the GOF plot twist made this conclusion even 
more likely; sort of a double bluff.

What do ya'll think?  Any takers?  Or can you point me to some canon 
that rules this out?
