when you play KOTOR1, you never get a light jedi holding a lightsaber that's got a violet jem inside. It's the Darksiders who have the violet powah.... (That was horrible i know) Anyway, Everything is a figment of your imagination because there is infinite space and fininte people finite/infinite= very very small number, ergo there is no population, ergo everyone you meet, have met, will ever meet, is just a figment of your deranged imagination. (Hitchhiker's guide to the galaxy)
Also I'm wondering How can you go through all these planets, depopulate them, and still get lightside points? The average lightsider only kills when he has to, but in the games you can kill like a maniac and still not have and consequences. Makes you wonder.
