"The one thing I hate about the PT, is makes Anakin like one of those people on Oprah Winfrey show, it is someone elses reason why I did it. I did this cause I had a bad upbringing, I did this cause one of my parents died early in life, etc. Lucas constantly gives an out to Anakin, and to me that undermines the strongness of Lukes character in the OT. Maybe Luke was just a stronger willed person than Anakin, nothing more nothing less. No two people are the same, and I think by constantly giving excuses to Anakin, what Luke eventually does in the context of 1-6, is really secondary now."
You would be right if Lucas didn't show Anakin questioning himself in Episodes II and III about his wants and desires. He openly admits in Episode II that what he did to the Tusken Raiders was wrong. When Obi-Wan asks what Padme would do if she were in his position on the gunship, he knows that she would do her duty, as he states. He openly tells Padme that "he wants more, but he knows he shouldn't"
Anakin is constantly battling back and forth between what he desires and wanting to do the right thing and be a good Jedi.
