I always want to play evil characters, because I really find the '' evil Sorceress '' thing to be really compelling. And then... I play the game and I can't bring myself to lol. I always feel terrible about it xD.
I definitely think that an issue in RPG's in general tho is that it's often just '' evil for the sake of evil ''. I think that there is an inbetween that is more like a scoundrel, the Rogue which I played actually did have a fair bit of those choices but few were story related. Mostly it was just '' what's in it for me? ''.
