One thing I noticed in the Star Wars universe that always bugged me:
The followers of Light v. Dark were never truly it seemed a battle of Good v. Evil. Their philosophies seemed to hinge on emotion v. no emotion.
Think about it. In Kotor the "sith" rise because the Jedi Order doesn't want to get involved in the Mandalorian War. The fringes of the Republic they are supposed to protect are getting spanked daily by raiding hordes and they don't give a fuck cause it ain't their problems.
A few Jedi led by Rivan say fuck that, we gotta go help. In doing so they realize the "no emotion" bullshit they are spoon fed by the Jedi order is kinda bullshit and when they fight with emotion (with rage and anger and lust for power and jealous) they tend to kick fucking ass. So a rag tag team of Jedi outsiders end up bulldozing the what amounts to be the Spartan's of their universe. They then decide, well fuck it.
Who is really the bad guy in that comparison?
The guys with unlimited power and numbers who could at any time come in and save innocent lives but don't because.. um... I don't know maybe they were busy?
or
Rivan and his crew. A small group of young eager recruits who decide to actually give a fuck and in doing so end a blood nasty feud.
I could see how they'd become disillusioned with the Jedi Bureaucrats and decide that maybe they should be the ones running the Jedi Order and fuck maybe the Republic in general.
And that is just one example. Every time I see or play or interact with Star Wars we see the Old Order as a bunch of Eunuchs who lost because they got way to into the idea that they shouldn't feel anything.
Kinda like the OP was saying, Luke became kick ass when he stopped being the pansy farm boy and started becoming the cocky adventurer who fought while tangled in emotions.
If I remember correctly he and one of his son's also eventually embrace the Dark Side or something at somepoint in the future. I picked that up on wikipedia or something somewhere.
Evil will always triumph over good because good is dumb.
This.
