Um, NOTHING.

The concept of a universally accepted "good" character is a caricature. What fits other people's criteria may not fit your own criteria.

For example, some people bring up Naruto; well I find Naruto pretty goddamn hypocritical. We're supposed to believe that a superpowered child soldier magically wants to make friends, rule the largest/most powerful nation and bring peace to the world? How is that any different from holding a doomsday device over the world and demanding total control?

Just thirding it....
Well... you wanted the pure guy who always does the thing he thinks is the best...

Liar game is another suggestion that probably isn't exactly what you want. ^^

Also, I think imercenary is right. A being that's always doing what it believes to be right... is one thing, but a whole other thing is a "morally correct person". Oh well, have fun searching 🙂

maybe saint oniisan. it's mostly comedy but I think it deals with doing the right thing and such

you can argue whether it counts since the main character hasn't really got the freedom to choose which would him leave without the possibility to be morally good or bad. he/it would be described as good though
