Here, look at it another way. Going back to what was said earlier, CF has absolute right and wrongs. There are, however, several different absolute right and wrongs. For example, the standard goodie-help-everyone-kill-evil version, the Battle-kill-all-mages version, the Outlander-treehugger version, the Tribunal-order-society version, and so on.

As Kasty pointed out earlier, the good vs evil one is possibly the most prevelant in CF. The goodie one is also possibly the most restrictive of all the paths to take. Certainly more restrictive then the evil path.

The problem you run in to with a goodie Rager, is that you're mixing two right answers, in the CF morality sense. That means you have to reconcile two correct world views that don't necessarily agree with each other. That's why it's much easier - and much more common - to play neutral Outlander/Battle/Trib, because you can more or less shed the alignment part and focus on the cabal part, or play goodie in the Fort, because then you focus only on the alignment side.

That doesn't mean it can't be done, and done well. It's just harder, and you run the risk of being put in situations where the two primary "moralities" are conflicting. If we made any one morality right or wrong, or allowed one to win, there wouldn't be much of a game to play.
