Eustace_Scrubb:
Well, _as far as we know_, that's true.  But given the perspective of
the books, we only really know that nobody's tried to make Snape "see
the light" in the presence of Harry or any other character who chooses
to confide in Harry.  I imagine that many people have chosen over the
years to have as little to do with Snape as possible, some who might
have tried to convince him of "the errors of his ways" probably tried
years ago and having failed, gave up.

The only character that I would think would be in a position to
sanction Snape for his teaching behavior would be Dumbledore (or for
brief periods McGonagall or Umbridge).  Dumbledore may have tried to
change Snape's behavior over the years; if he has, it doesn't seem
like the sort of thing he's going to blab to Harry.  But Dumbledore
may also have simply tolerated this behavior because he needs Snape
and can't afford to have him appear to be a truly changed man.

McGonnagall's period as Acting Headmistress was brief and tenuous. 
Umbridge probably approved of Snape's methods, except of course for
the fact that he had the students make actual potions using real
ingredients, rather than just read about them in books.
