It has been widely shown that the dark side is the quick and easy path to power, and that many fall because the lure of that power is too great for them to resist.
See, I don't agree with that.
I think a lot of people who choose the dark side do it because it offers less restrictions. Less rules saying what you can and can't do. I don't think most do it just because it's the "easy" way to power. I think that's just a huge side benefit for many.
