Jenni from Alabama responds: You asked for proof (Canon) that Snape 
called/referred to Lily as a Mudblood. Here it is. 

Am. Edition pg 648 Order of the Pheonix:

"LEAVE HIM ALONE!" Lily shouted. She had her own wand out now. James 
and Sirius eyed it warily.
   "Ah, Evans, don't make me hex you," said James earnestly.
 
  "Take the curse off him, then!"

James sighed deeply, then turned to Snape and muttered the 
countercurse.

   "There you go," he said, as Snape struggled to his feet 
again, "you're lucky Evans was here, Snivellus -"
 
 *****Here it is*********Snape is talking here*********************
 "I don't need help from filthy little Mudbloods like her!
*******************************************************************

Lily blinked. "Fine," she said coolly. "I won't bother in the 
future...."

So, I was mistaken in that Snape didn't say it TO Harry. Harry heard 
it/saw it all in the pensieve. But, he does call her a Mudblood. 

Notice Lily's reaction. She's stunned! Here she is defending the 
jerk and he trashes her! That is hitting below the belt, IMO.

Jenni from Alabama responds: This is, of course, possible. However, 
given Snape's past behaviors, I doubt it. I mainly feel that Snape 
showed his true colors on that tower and really is a bad guy, a 
death eater and evil. But there is that little part of me whispering 
that Snape will redeem himself somewhat by saving Harry in the 7th 
book. 

Jenni from Alabama - in response to some other posts:

Yes, Snape has saved Harry in the past. But - as he says to the 
Death Eaters at the end of HBP when they try to hurt Harry 
(page 603, Am. Edition):

"No!" roared Snape's voice and the pain stopped as suddenly as it 
had started; Harry lay curled on the dark grass, clutching his wand 
and panting; somewhere overhead Snape was shouting, "Have you 
forgotten our orders? Potter belongs to the Dark Lord - we are to 
leave him! Go! Go!"

I think LV had Snape 'save' Harry to gain DD's trust. To make it 
look like Snape was really on the Order's side when he truly is/was 
a Death Eater.  Waiting for the voice/whisper. Yep, there it is.

Jenni from Alabama (wishing the voice would just shut up!)
