Sue:
Another consequence of the same action was that the world now knows 
Voldemort has returned.  As the story goes this is probably the most 
important consequence of not using the mirror.  If Harry had 
discovered Sirius was safe, he would have known Voldemort 
was "messing with his head" and would not have gone.  We would have 
another year of "hem hem" and horrid things being said about Harry 
and Dumbledore.  

Perhaps then, it could be said that Sirius's life was sacrificed to 
save the WW and more specifically, those people he cared most about.  
Not such a bad reason to die, really.
