jedi knight dark forces 2, how do you fall to the darkside?

in the game jedi knight dark forces 2, how does one fall to the darkside of the force.??

I just started to play the game a little bit after letting it sit for a couple years.

 

Kill all the civilians, and when you get to choose new force powers at the end of each level, allocate your stars to the Dark Side powers (Grip, lightning, throw etc)

 

Kill friendly npcs, kill unarmed enemies, assign stars to darkside powers and use them. After the fight with Maw you should see the darkside cutscene.

 

Or, if you don't want to have to kill every single freakin' civilian....(THIS IS A CHEAT) use "Sithlord"
