Seems to me that Lupin, not Snape would have more reason to be mad at
Sirius.  Snape might have been killed, but as death effects the living
more then the dead (who can no longer feel, except if they return as
ghosts).  Lupin would have to live with the fact that he killed a fellow
student for the rest of his life, which would have been a horrible thing
for Sirius to have inflicted upon Lupin.  Surprised that Snape and Lupin
didn't become friends over this when they realized they were both
victims.
