It is a joke, but you are being too simplistic in your positions [member="Hion the Herglic"].
While I wholeheartedly agree that Dark Side is inherently destructive, it does not mean that all characters aligned with it are evil. Dark Side instead of harmony and peace with the world utilized fear mostly, fear for oneself, fear for losing something, that is the most basic feeling from which later derives hatred and other goodness. That and the good old proverb "The road to hell is paved with good intentions", which can be the cause of many's alignment to the Darkside - their unrestrained will to help others and pain of watching others suffer.
However, the same thing applies to Lightside. If Jedi do not find balance in their role, if they relentlessly engage in a war and cause suffering, then they are no better than Sith and actually very much risk going Dark. Lightside might soothe them, instead of driving like the Dark, but in war that's a very fine line that's easily crossed. Which brings me to my next point.
SW has a number of original characters that have change alignments and it doesn't just go one way. Simply saying that those that use Lightside are good and those that use Darkside are evil, villains is majorly nerfing the complexity of any possible character, ignoring just too much in my opinion.
P.S. Watch me make a Sith that wears pink, makes illusions of unicorns and rainbows and feeds on the confusion of his enemies, also performs other unspeakable horrors.........
nah, I won't do that, but my point is that force is not something that just makes the whole SW world bipolar on goodness/evilness. My opinion is essentially what
