Hi Raven Heart (I love that screen name by the way.)

But they DID alter history when they undid Buckbeak's death. They
HAD already killed Buckbeak before Harry and Hermione used the time
turner. They altered time and undid it. They changed history, the
space time continuum, whatever you want to call it. So, in theory,
they could alter history and prevent/undo Harry's demise. <snip>

  Raven Heart:

  Was buckbeak killed the first time the events occured? They never actually saw Buckbeak killed, only heard the cry of Hagrid, which they later found out was a cry of joy that Buckbeak somehow escaped. Events happened the same the first time they experienced them as they did the second time, the difference is only from the point of view.
