Yeh, seems to be proper evil choices, with proper evil consequences. I play the KOTOR games as a bit dark side usually, and those games are pretty much evil = being a comedy jerk in a few limited interactions.If you're the type to feel bad about videogame choices, this one will REALLY make you feel bad. Ex, super gorily stabbing your teammate's eyes out with a dagger in closeup to kill them, reducing your party to pretty much just be the "for-hire" generic characters, that kind of thing. It's not like Mass Effect 2 or whatever where being a dick was hilarious.
I liked this game a lot and would like to play through it again but it sounds sort of exhausting still. Maybe in another couple years. It took over a hundred hours!
