I think Snape is good. I think he has been mistreated and misunderstood for so long. And...I think the spy that Voldie is talking about in Goblet is (whats his name?) the guy who impersonated Mad Eye Moody...and in Half Blood Prince Draco Malfoy. Snape has always had an eye out for the students, he helps them and protects them from the begining. (see my posts on the clues form book 1). He didn't have to warn the Order about Harry and the DA going to the Ministry to find Sirius....but he did...and subsequently many death eaters were killed, maimed, arrested and Voldie didn't get the prophecy. He didn't kill Harry when he was running away with Malfoy..but he could. He helped Lupin by brewing the Wolfsbane potion...even though he didn't like him personally. There are so many many things I could say but I'll leave that for later posts. My answer ultimatly is...Sanape is good and we shall see the role that he fills revealed in the last book.
