PT Dooku- a well-intentioned man who fell from grace?

"Even though I knew that the Senate was corrupt, the Council was fallible, and Jedi training methods far from perfect, I remained with the Jedi Order for twelve years after Galidraan. Why? Because I still believed that I could accomplish some good as a Jedi. I thought I could bring about some positive changes, right certain wrongs, and do better than maintain the status quo. In short, I was an utter fool."

Please use this thread to share your thoughts on the character of Dooku. Was he a victim of Darth Sidious who twisted his good will into something nefarious? Could Dooku have been redeemed or did he lack a saving grace? Or was Dooku just an arrogant aristocrat who was listening to his own ambitions and not to a higher calling? Please discuss.
