ariston wonders:
Isn't the fact that Quirrell jinxed Harry's broom a tipoff that he 
was interested in more than just immortality for himself?

If at the end of GoF Snape went to worm his way back into Voldy's 
good graces, my best guess is that he either: (a) pretended to 
switch sides again (something like, "My Lord, I deserted you before, 
but I have returned to my true home, where I have always belonged.") 
or (b) openly stated that he was a mercenary like Pettigrew who 
always follows whoever he thinks will "win", and that this time he 
thinks that doddering old fool Dumbledore is bound to lose, so here 
he is, at his Lord's service.  (Voldy knows that Pettigrew isn't 
really loyal to him, so this might have a slim chance of actually 
working.)

I'm not at all sure that Snape *has* wormed his way back into 
Voldy's good graces.  But if he did follow either of the above 
options, either one could well have been followed by a little crucio 
action or worse -- which would explain why Snape & Dumbledore were 
so apprehensive about Snape's task at the end of GoF.
