Snape, A Hero

I have to admit, Professor snape has been my favorite character throughout the series.  I know, he's greasy, mean, sarcastic, and rude.  Still, I can't help but to be drawn to him.  I was suprised when he apparently killed Dumbledor on the tower, but I truely believe that there is much more to it.

First, Snape has been a true hero in every book.  He has protected Harry over and over again.  Actually I dont have enough room to elaborate on that as much as I could.

Second, I have to say that his treatment of Harry is deserved a lot of the time.  Harry is very rude and disrespectful much of the time.  Not just to Snape, but everyone else.  He appears at times to have a head as big as an oversized beach ball.  I wonder if Snape's critical treatment of him isn't a way to ground him a bit.  Even Dumbledor fawns on him.  Have you ever noticed what happens to kids who nobody ever corrects?  (example: Draco Malfoy).  I know this probably wont be a popular arguement, but I truely believe that Snape has had Harry's best interests at heart.  I would call it tough love.

Third, I just have a gut feeling that Snape is truely a good guy.  Remember, Dumbledor trusts him therefor, so do I.  Please feel free to share your thoughts.
