My question was aimed specifically at those who, like me, consider such characters as giths, Sharrans, and vampires to be evil, and making a pact with a devil and trying to usurp a god's power to be at least morally highly questionable if not evil (at least at their starting points in the game with no consideration for how they may subsequently change). For those people here, if they're inclined to play an origin even while also wanting to play a truly good PC, what is their origin of choice (and why)? That is my question.
That's a good question... there is none as far as I'm concerned. There isn't a single origin character I'd consider genuinely good, at best there are some lighter shades of grey. For us good guys, the only real option is a custom character.
I don't consider a pact with a devil as inherently evil though, it may have been formed with the best of intentions. Certainly not the wisest choice and one you'll certainly come to regret, but who said Wyll (or any other Warlock) is wise?
