"So, here we have it, from a Battle Imm's mouth. Ragers are misguided. Magic is, in fact, not forbidden or dangerous to Thera."

Okay, now you're being silly. Of course in-character Kastellyn believes Ragers are right and everyone should kill all mages. Kastellyn the Character wont give two ####s about your alignment or the mages alignment. In fact I seem to remember him stating clearly that he would be applauding a goodie Rager killing a goodie mage, at the same time he was sliding his alignment toward neutral.

To paraphrase myself again: Rager mentality doesn't lend itself very well to being good.

In CF land, there are multiple "right" paths. Every cabal thinks they're right. Being "good" is one of those "right" paths. So is killing mages, enforcing the laws, burning down cities, and more. Forum Kasty - and all the rest of us - can easily admit that our cabal's path isn't the one single truth.
