The only reason I'd like for not being able to do a quest is reputation or economy or in the sense that in real life, or.. lets say in that generation, and in that history and story line, you wouldn't able to solve the quest for the city watch after you were first, a wanted killer (or something evil) or if you were against the idea to begin with.

What I mean is that, the only reason you shouldn't be able to help the evil side would be if you were well know on the good side, representing your side.

But in the case were you only have 5/10 options to choose from and allowing the rest or the other 5, to not be in the characters game, would only be good to your character if in doing those several quests, they would have a certain chain of outcomes depending on what you picked.

So if you helped the poor, instead of those of which are rich, you would embark on a journey to the Beggars corners, in which people would thank you, and more quests would show up, but being on the Rich side would lead you to a big house etc. Therefore allowing your character to be placed in the world with limits.
