im still opting for snape , snapes really clever hes a master at potions highly skilled oclumecy (or w/e) he managed to stay on both sides , voldemorts & dumbledores who are both highly skilled leggimency (or w/e lol) ....which is his true side ... i duno but personally i think he,s good & if that was true just think what a risk he was taking lying to voldemort ....same if he was on the dark side
