Nobody is "good" or "evil" all the time. I like that hard-coded moralities aren't present in Skyrim. You always have a choice, as it should be.
i dont think anything should be coded in to affect what choices we can make, id just kind of like to see more of a reaction from people based on my alignment and also some more dialogue options for those of us that like to RP. only having one dialogue option in a quest that says "ya sure id love to help you" when in fact the only reason im "helping" is to get gold or loot or whatever. BG2 covered it pretty well, every quest had a good, evil, and neutral dialogue.. your decision wouldn't always affect the outcome of the quest but it would the reward for it. such as, a good character would say "no keep the money, i just want to be a good dude!' an evil one would say "thats it? this is all you give me for saving your town? i demand more or ill burn this village to the ground!" mainly i just think some added dialogue would be good for the people that like to RP, this is an RPG afterall, and it gets dull sometimes to always see the same dialogue no matter if i am a murderous killer or a holy paladin
Can't say I every liked these kind of ideas. People do what they want and few can ever be labeled as strictly good/evil/neutral. On that note I think being a neutral character is very simple, just worry about yourself. Had a hunter once that played by that rule. Hunted animals for money, would do a bounty if need a bit more but was just someone worried about taking care of themselves and not the woes of others.
in most fantasy settings the concepts of good, evil, law and chaos are rules of the land that have as much of an impact on their world as the laws physics do to ours, there are in fact "wholly good" and "wholly evil" characters, take a paladin for instance, a paladin can *only* be a paladin if they adhere strictly to the forces of law and good, there is no grey area, if a paladin commits an evil act for whatever reason they lose their connection to the divines and become a "fallen paladin" there are no exceptions, there is no "for the greater good" excuse. a paladin cant lie, cheat, steal, or murder. period. if they do, they cease to be a paladin
