in the sense that if I throw a gnome off a cliff its like 1 less person in the world I need to talk to and therefore is making my quest on a whole easier?
More like if you kill the bad guys instead of joining them, you will never see all the dialog they wrote for the dark side - and they want to show that off.
other games: most players want to be heroes, so we throw in evil choices only to give meaningful contrast to the good ones.
BG3: evil storylines should be as fleshed out as the heroic ones, we just need to convince more players to explore them so the work isn't wasted..
