Nirth: Easiest way to explain it is that the dark side of the force tampers with forces that isn't natural so you pay the price when using it, it disfigures your body which I take it as a symbol of how your soul looks like due to the evil you spread or something like that. :P
Elmofongo: I don't know, why are Jedi such morally absolute prudes :P
Jedi says there is no passion there is serenity yet aren't they passionate about the Light Side of the Force.
And isn't denouncing love a fear in itself?
Nirth: They just have different philosophy about life. While they're passionate about their own beliefs it's not what they mean with "there's no passion", it's about being unselfish and helping the weak. They want harmony and balance, therefore restoring the weak to 'middle class' status and killing Siths because they reached way above 'upper class'. As for the absolute part is to avoid distracting influence, that goes for both the light and the dark side
I forgot about the love part. In a way you're right but I think it's to avoid distraction, Yoda mentions in the older movies that a truly great Jedi has complete focus on his current mission, you won't have that with love in your life or any high emotions like passion, anger, excitement.
Love can easily tempt someone to the dark side.
tinyE: I know this has nothing to do with GOG but it is kind of game related and I respect the opinions of you folks so here it is. I'm playing KOTOR 2 and I can't get over that be it in a movie or a game the Sith are all so ugly and or horribly disfigured. It's almost like they can't become Sith until they've had multiple limbs hacked off, eyes removed, been dumped in lava, sprayed with acid, dried up, skinned, deep fried, minced, etc etc etc. I understand that as tradition goes the bad guy needs to be ugly but in all the movies and games from this saga they couldn't give us ONE SITH that had all of his face or skin!? It makes me wonder if Lucas Arts (Disney) is just out to convince the world that good looking people are good and ugly people (worse yet disfigured people) are the root of all evil.
Well, if you live the life of a Sith, it is only a matter of time before you get a limb hacked off, an eye removed, sprayed with acid, dumped in lava, have monkey poop thrown at you etc. It's not like these guys make sandwiches for a living or stay home all day. They are around people who constantly want to kill them. Jedi and other Sith. :)
Stevedog13: Simple. Ugly people have a hard time trying to get laid. It first makes them bitter towards the opposite sex, then to the good looking people and eventually to everything capable of procreation. Normally these type of people are kept in check by their own awkward insecurities, but give them access to a power like the Force and -BAM... instant Sith.
And bitterness leads to anger, anger leads to hate, hate leads to the dark side... :)
