i had the hangover for about 3 days after cried tears for proff D.but still i somehow think snape is on the good side.i am not a great fan of snape.but still i do think he is good. do you have any theory for snape so strongly professing "dont call me a coward." because if he played the role of a successful spy he must have some nerve doesn't it?but then again in the first book we come to know that professor dumbledore was a gryffindorr. and we know that even neville was brave enough to stand in froint of the death eaters.so obviously a man of dumbledore caliber would never pleade for his life.he was a WISE in every sense.and BRAVE in every sense.since both snape and dumbledore were gerat legillmens they spoke through the mind. and hence pleaded snape to kill him instead of forsaking the unbreakabel wow.maybe indirectly snape can direct harry to the rest of the horcruxes once he has won some amount of trust in voldemorts eye.and about snape convincing voldemort to spare lily's life,do you really think voldemort would depend on anyone to influence his decision. i think no. what about you?
