That's not a true RPG though a true RPG allows you to be anything from Chaotic good to Lawful Evil
Well, more or less there needs to be a Middle ground in these games, just you know, neutral. People like to play through these games and see all the content unfold, it's best to keep it as simple as possible (Good, Neutral, Evil). Neutral ground seems to be lacking from most "Choose your own adventure" RPGs nowadays.
Or if you're going to make it complex, make it so all the more important content remains available to you somehow, to avoid frustrations.
