There's all sorts of ways to look at morality choice in games.
While we all (myself included) rage against the black-and-white morality in many games and see them (very reasonably) as offering only illusions of choice, they are representative of how society perceives and rewards behaviors. You can either be by the book, or you can be a maverick, but games like Mass Effect take the view that it doesn't matter what you do, as long as you're consistent someone will respect you. Cynical, but we can certainly relate to politicians and business persons who appear to be dead wrong about so many issues, but from adhering to a consistent set of principles, earn a following.
A game like Paperboy is interesting though because it penalizes for doing some "wrong" actions, but allows you to carry out others with reckless abandon. It's a very selective morality wherein your only compass of "wrong" is what someone tells you not to do.
On the other hand, doing everything "right" is a self-imposed challenge that in the end will probably only matter to you. Likely no one will notice it, and the only thing you'll gain from it is a feeling of satisfaction.
And before we get into "reading too deeply", I don't care if it's navel gazing. The right navel can be a great place to gaze.
Especially when you're waiting for the end-of-shift whistle to blow at work.
