Last night, I saw an amazing video on youtube involving Obi-Wan that kind of helps define his character. http://www.youtube.com/watch?v=ztrxYSMpJHw

If you think about it, Obi-Wan went through a lot of trauma and life changing experiences throughout his life. I mean, he lost his master at a young age, he witnessed the deaths of hundreds of Jedi that he knew, he lost his best friend to the dark side, he was forced to cut down Vader and he ended up living a hermit's life for around 20 years.

Yet he survived numerous battles, killed Darth Maul, an Acklay and General Grievous. He also defeated a young sith named Vader. His only nemisis seemed to be Count Dooku. I believe that Obi-Wan would not have made the same mistake that Mace did in trying to kill Palpatine.

With all those triumphs and sufferings, he has earned a lot of respect from me.
