Quoth Nightmasque:

>It has been pointed out elsewhere that all the Slytherins who were on
the 'good side' so to speak were given ulterior motives or doing so,
i.e. Snape's was Lily.

Then Magpie:

> [Snape's] not the only Slytherin to sacrifice himself--they
> just sacrifice for reasons that mean something to them even when
> they're doing the sacrificing. So even Snape's redemptive sacrifice
> was, imo, a personal one that didn't go beyond himself as it could
> have.

Now guzu:

While I don't disagree with what is written above, I think a little too
much credit is given to the non-Slytherins. I'm sure plenty of them were
fighting, not to help Muggles and Muggleborns in general, but because
their personal friends and family were in danger. To put it another way,
if Hermione had been pureblood, do you think Ron would have been just as
willing to sacrifice all he did?
