well, I've always assumed that he did all the regular Death Eater stuff... I mean, I don't know if they all went around killing, or if they mostly did the torturing, and Voldy was usually the killer. But I do think, whatever the other Death Eaters were into, it's also what Snape was doing. I wonder, though, when he became a spy, like, did he try to come up with ways to
stop doing those things? and how could he have managed stopping his torturing or killing or stuff like that without becoming suspicious...
maybe there are different jobs in the Death Eaters just like there are in the Order.
In the Order, there are different jobs. Molly is in charge of the people, making sure that their needs are met as far as clothes, food, working on cleaning the house. Arthur seems to be the authority figure at 12 Grimmauld Place, he also is an eye in the ministry, along with Shacklebolt and Tonks. Lupin is kind of the comforter, an an outreach to other non-desirables. Mundungus serves as the eyes and ears in the criminal world. Dumbledore is obviously the head of everyone, and Snape is a spy inside the Death Eaters circle.
Now, maybe the Death Eaters have different jobs, too, so Snape's particular job wouldn't really mean he'd be one of the ones out there killing or torturing people. Maybe Snape's job in the Death Eaters is a spy at Hogwarts, but I don't think he's really a double-double-crosser, so I think he'd be giving Voldy inaccurate or incomplete information. The deal with Snape is he's the hardest character to figure out...
Anyway, I've rambled enough.
