JKR's opinion of Snape

Why did you make Quirrell the bad guy instead of Snape? 
JKR: "Because I know all about Snape, and he wasn't about to put on a 
turban." 

>From the mouth of JKR herself! Does suggest that Snape would not 
willingly help Voldemort!

That leaves us with Good Snape or Snape Only Out to Help Himself!!

It is possible that Snape has bided his time before killing DD, and now 
knows he can use Harry to help him destroy Voldemort.

I am still in the Good Snape camp though!!
