Moral choice systems in games are still maturing, but as far as I'm concerned, Bioware has definitely explored this the most effectively. I see a lot of love for Mass Effect in the thread.
Any of you guys play Jade Empire? That was one of my all-time favorites in terms of role-playing/dialog/branching stories, and one of the few games where I could actually stomach playing through the story as the "evil" character. Instead of calling the moral system in the game "good vs evil", it was about two competing philosophies, "open palm vs closed fist" or something like that. Following the way of the Closed Fist often made you a grade A prick, but you were never being evil for evil's sake. The philosophy was all about valuing strength above all other values--let the weak fend for themselves, not out of cruelty, but because the struggle will make them stronger. If you take away their incentive to struggle, you promote weakness. Etc.
While the Bioshock series has thus far had a pretty rudimentary moral choice system--not quite evil for evil's sake, but evil for power's sake, its exploration of the pitfalls of strict individualism or collectivism are way more mature than most of what the gaming medium has had to offer.
