I've just started the quest for the first time ever, (despite having Skyrim for over 12 months now..) and I'm stuck on choosing which follower I should sacrifice to Boethiah.

Can anyone recommend a follower to me? Ideally someone who is a jerk and isn't tied into any quests.

Ah, this would be so much easier if Nazeem was a follower! xD

For me it was Faendal. He served me well but his usefulness expired.

I use the mercenary in the Bee abd Barb in Riften. He,s expendible.

Jenessa. One thing I don't understand is how boethiah thinks I can kill someone in cold blood aka stealth when its clear I am not an assassin or stealth focused in any way.

I deceived the Prince of deceit and exploited the game, so that the mercenary who 'volunteered' came straight back to life afterwards c:

I typically use one of the random mercs from the inns.
