Cookie246122: Why did you kill Sirius? It made me very sad :(
JK Rowling replies -> I'm really, really sorry. I didn't want to do 
it, but there was a reason. If you think you can forgive me, keep 
reading, you'll find out. [I feel really guilty now].


vmonte here:

JKR loves the character of Sirius.  What would be the reason she 
needed to kill this character off?  It seems to me that DD tried 
several times to save Sirius, by making Harry and Hermione time-
travel, and by keeping Sirius at GP.  DD said he made a mistake with 
Sirius--he realizes that he should not have forced Sirius to stay at 
GP.  If DD has time-traveled I think that he has changed some events. 
And I think that he has changed some past events for the better and 
some for the worse. I don't think that time-travel is as rigid as 
some fans believe.   

What if DD has been changing history through time-travel but Sirius 
messed up his plans by changing himself from secret keeper.  

And what if Harry time-travels back and young Sirius realizes that 
his actions are what caused Voldemort to find GH.  If Sirius were to 
find out that in the future he was going to die no matter what DD or 
Harry did, he may change what he does in the past.  I'm not saying 
that Lily and James survive, but maybe teenage Harry was also meant 
to die at GH. Sirius may sacrifice himself in the past to make sure 
that teenage Harry Potter lives.  Sirius would then die in a nobler 
and more fitting way.
