I don't really want to sacrifice good NPCs, are there any evil followers?
I went with Marcuio (Riften) because he was really pompous. And it was him or the Whiterun guy with the ram-horned helmet that made a lewd comment to my char (female, because I'm a female). Being someone who gets tired of that in games, ....yeah.
The odd thing is that I take Faendal usually because the story line really seems to get you to walk a morally gray line at least, which I have no problem with, but he keeps my char in check.
