I wouldn't rush to that conclusion until we see the book.
Um, Vile has been out for a long time. And unless the ink moves on the pages, there is no seriosu discussion of evil in that book, unless you define evil purely in terms of deviant sex and drug use.
Deeds could have an excellent discussion of 'good' but that's only half the argument. It's like having a right/left political discussion with only one side represented - you get a very thourough grounding in one argument, with biased superficial (at best) summary of the other.
On an unfair personal level I do doubt the extend to which 'good' will be discussed also. D&D writers seem to get really squicked when they have to actually deal with specific discussion of alignments.
As long as we have good and evil as cosmological concepts in D&D (ie, detect evil) it will always be black and white to a degree.
That's great - but what's evil? Murder, stealing, self-gratification at the expense of others? Fine, but that is what the average adventurer does when they rob the dungeon. Is it serving demons - fine, but why do people serve them when Celestials are 'better' (mechanically speaking)? Make things too black and white and certain classes (cough*paladin*cough) become unplayable because their morality restrictions reduce them to the level of a very poor AI, running of basic IF-Then scripts.
However, that doesn't mean that there isn't room for argument between two positions which would both be considered good. I'm not drawing any conclusions as to how it will treat it until I see it.
I'm keeping a hopeful open mind about it, but my opinion is influenced by their past products and positions on arguments about alignments. They flip flop far more than they should.
