Right and Voldemort somehow managed to make Horcruxes without being a brotherhood member...a horcrux doesn't a brotherhood member make.
By making Hermione 'his' I can't really see him accepting anything less than her having at the very least the length of life she was due to have.
I don't understand the desire to save the Slytherins who still persist on being evil. It seems to be rather counterintuitive. Why save the guilty at the expense of the innocent?
Thanks for writing,
I thought the first point had been covered in the story already. In any event, that will be made clearer later. As for the Slytherins, they are a bit smarter here than in canon -- some, remember, are moving to Harry, just not all of them
