When I said "one thing that [his] analysis can't explain very well: Quirrell's involvement with the plot to get Harry's friends" I was falsely thinking that only wholly evil motivations could motivate that plot. But it could have easily been for some distorted and twisted version of the greater good.

I don't like the idea of RidVolQuir being wholly evil, such beings are improbable. I initially hoped for and thought I would receive a sympathetic Voldemort. Unfortunately I no longer think that's going to happen because I think that the post dementor attack Harry evil mode which wanted to kill everyone is meant to be evidence that Harry is Voldemort's Horcrux, which would also indicate that Voldemort's soul is inherently and totally evil. I don't like that idea and hope my prediction is wrong.

The grandparent of this comment made me feel a little better about the odds of a not-totally-evil Voldemort, but not very much better. Now that I think about it though, since RidVolQuir has thus far been portrayed in such a way that allows the reader to sympathize with him, maybe even a Voldemort with the automatic killing response would still somehow manage to be less boring and more realistic than I anticipate. That seems like it would be tough to pull off though.
