Personally, I agree that Snape is an interesting character, that he
adds a lot to the books, and that there is clearly more to him that
we have yet to learn. However, I also think that wanting to know
about/thinking there is a back-story and motivation for certain
actions (say, his treatment of Harry and Neville, to use one of your
examples) is no more valid than theorizing that he's treating them
that way simply because he is a bitter, nasty man.

S.D.
There is also the fact of course that Snape (and I'm un unabashed 
Snape fan) at the points in which his treatment of Harry and Neville 
was extreme could have (and this is a theoretical point) been being 
watched by the Death Eaters, now remembering that to be an efficient 
spy they had to belive that his 'redemption' had been as phony as 
their own this victimisation of 'The Boy Who Lived' would have come 
across as a very easy way of showing continued loyalty.

As for his grudge against Sirius and James, I think most people 
would have one against the people that had treated them the way he 
showed in his memories during OoP.
