Fine. But realize that you are using house rules to do so. The game is written with few 'shades of grey'. It is written with as much black and white as possible.
Indeed it is. That's why Rule 0 is the most important one in the game.
As for 'shades of grey' helping to attain some level of internal logical consistency, if carried to an extreme, you end up with the same problems that haunt many young authors that try to avoid the 'black and white' that most successful authors use: Everything that the protagonists do is ethically questionable and the players/readers never get a sense of satisfaction from doing/reading questionable triumphs. I've seen quite a few games derailed when players left a session depressed because they killed the orc chief and all his warriors, but were forced to either slaughter the orc women and children or leave the widows and orphans to be picked off by neighboring monsters. Fantasy settings where things are balck and white instead of 'shades of grey' often fall into easier logic than real world situations where there is no single right answer and a variety of answers that are different degrees of wrong.
As far as taking things to the extreme goes, I would hope that most DM's would have enough common sense to employ moderation. Sure, if
everything the protagonists (read PC's) do is ethically questionable, then it becomes almost as unrealisitic as the pure Good v. Evil approach, but that's true of any extreme. It's also true that you can achieve a high level of logical consistency using black & white morality, but that doesn't necessarily make it better. That's just the tack the writers of D&D took when building the game, but it's not set in stone. It's all a question of what style of play you prefer, weather or not you want to use real world logic or game logic, the latter of which tends to sacrifice consistency in favor of game balance.
Many DMs really enjoy giving their PCs 'real world' shades of grey in the campaign. In my experience (24 years of pretty solid role playing with dozens of different groups), this often is far more enjoyable for the DM than the players. Players enjoy the sense of satisfaction from besting a truly vile foe. They feel less happy when their heroic character is forced to battle to the death with a champion that is only trying to protect his tribe from people with conflicting goals. This is not true of all players, but even those that profess that they enjoy the moral quandries have shown themselves to really enjoy kicking the butt of a great evil.
Of course, everybody likes to kick the butt of truly vile opponents, I agree 100%. But, like you said, not everyone likes their morality drawn in such clear lines. Some players do and others don't.
The best solution I've found is to provide a mix. Yes, there are truly evil SOB's out there that are irredeemably corrupt and need to be smited for the greater good of all, but I try to make such confrontations rare (true evil doesn't grow on trees, y'know?

). Most situations are alot more complicated than "those are the bad guys, we kill them and good triumphs" and that's the way I like to both play and DM.
