billd91 said:He's deep-cover Snape, determined, even ordered by Dumbledore, to act the part fully until the time is right to take Voldemort down even if that means he might be maneuvered into directly attacking Dumbledore himself. But, that's primarily after Voldemort is reborn. Until that time, Snape is a forgiven man (forgiven by Dumbledore) but still fundamentally a titanic jerk with lots of grudges. He wouldn't be interested in killing Harry, not being an evil man to the core, but torment him by using his power in a juvenile way? Oh, yes. Most definitely.
Viewed like that, Snape makes sense.
No, it doesn't. Snape's done things that are recklessly stupid if he genuinely wants Voldermort defeated (being willing to see Harry, Sirius, and Lupin suffer minor discomforts over a petty grudge is one thing; being willing to see Harry be possesed and used as a catspaw, Sirius executed, and Lupin fired is another thing entirely), things that are recklessly stupid if he doesn't (quite frankly he could have done a lot to help Voldermort's plans along without anyone knowing about it), and things that are recklessly stupid if he's playing both sides against each other and hoping to come out on top himself (most notably taking an Unbreakable Vow when he either didn't know what it was going to lead to and was stringing Narcissa along, or did and knew that would mean setting himself up for a direct confrontation with Dumbledore). And yet the general impression you get is that he's neither a reckless nor stupid man.
