Just don't have it in me as it just bothers me morally for some reason
It's a path usually structured terribly with no inspiration with very little variation and makes me feel like the game's either a) punishing me or b) trying to shame me for taking the evil path. Also, I'll echo a constant complaint, there's not a lot of subtlety in most evil playthroughs because it's murderhobo evil; not like my ex girlfriend, a selfish and calculating evil. I'm no storyfag it's just that the evil playthrough can usually close the doors on most of the neater stuff the devs put in there (see item a).
