Wait. What makes you think I wouldn't immediately jump to the dark side? They're WAY better than the light side! They get lightning powers and choke powers, and good guys only get jumpy powers and boomerang lightsabers.
Plus, think of all the hot Twi'lek chicks the dark side gets at their cool dark side parties, while you wimpy light side people are staying at home studying your jedi handbook.
You will eventually become pale and deformed. Your anger and hate will define who you are, leading you to push away those who are close to you. Your apprentice will eventually kill you, and the cycle will begin anew.
Also I read somewhere that there is only supposed to be two Sith Lords at any given time. Which means those parties will have a pretty small turnout.
Beneath the gold, the Bitter Steel.
Yeah, and jedi never let anyone close to them because of their troop leader says he doesn't want to deal with cooties. Might as well enjoy the fun while it lasts, and enjoy other people's misery when all the fun is gone.
And hey, it's not just Sith that get to come to the party. Bad guys gotta stick together; that means bounty hunters, slave owners, car salesmen, everybody!
