Do...or do not.
<...as Yoda said, "Fear leads to anger, anger leads to hate - and hate leads to the dark side."
Maybe so, but if Luke had stayed on the farm and Ben stayed in the desert, and nobody had gone out to kick the Empire's ass, the galaxy would have wound up a very different place. And I notice Yoda can kick a lot of ass too. You don't have to hate to get the necessary job done.
The advantage was that in the case of Star Wars, the WMD (The Death Star) was a little easier to spot.
