Jolee - Sorry, the Jedi order is not perfect. So Jolee not being a perfect jedi is not a reason to brush him aside. He has a compassion about him. He cares for others. Plus wisdom is a wonderful thing.
HK-47 - There is a quality about him that shows pride in his accomplishments. While brutal and cruel, he is not ashamed of himself. He teaches you to be proud of who you are. Be proud of your work. And of course I'm kidding about him being a role model.
On the comment the ends never justify the means... Suppose all that killing done in WWII was not justified. No, I'm not just talking about the soldiers who died. Entire cities were leveled to save countless more lives. If you want a real discussion on the practice of evil to do a greater good, I'll be happy to discuss it, but not in this thread.
