Or maybe Lucas can make a new movie that utilizes "Revenge" in the title and salvage that coolness . . . . oh wait.
Also, the concept of the "Jedi" clearly changed from the 70s/80s of the OT to the lore that the prequels started later on. In the OT, they were guardians and peace keepers, sure. By the PT though? No marriage, weird codes, etc. The Sith are even stranger. And let's face it, even with those changes, it's not like Yoda and Obi-Wan are seeking justice when they go to confront Palps and Anakin. They both are out to put their head on a silver platter. In fact, Yoda seems angrier and more of a wise *** about it than Obi-Wan does. Instead of Obi-Wan giving Anakin a mercy kill, he leaves him to ****ing rot and burn to death. Ohhhh yeah, that's gallant.
I always thought Ben, Yoda and Luke were pure of heart, even if they dabbled in what their universe considers sin. That means revenge. Revenge isn't always killing brutally, it's not always deadly.
