I'm not really saying you're wrong. All I'm saying is fear drove him to that point. It's the fear of losing the one he loves. It's fear of letting history repeat itself when you know in your heart that you can make a difference. That's all Anakin's problem really is. He loves Padme. Life without her isn't life. If he feels in his heart that he either has the power or can obtain the power to save her, he's going to do it...everyone else be damned.
And it's not like the Jedi didn't give him reasons to turn his back on them. They openly used him against a person they knew he was close to. Sure, he's a Jedi first and foremost but just look who Anakin is in the Prequels. Anakin is loyal to people he loves, not ideals (Ideals the Jedi try to teach him. Why is he this way? Because of his age...hence the reason why Lucas had him at nine in the first film). This is why his fall to the Darkside thematically revolves around people he cares for.
He's loyal to Palpatine. He's loyal to Obi-Wan. He's loyal and loves Padme and his Mother. The Jedi should've know better than to put Anakin in that situation. Why do you think Obi-Wan was reluctant to ask him?
On top of all of that is the disrespect factor. Obi-Wan kills the first Sith in a millennum and he's promoted to Jedi Knight without question. Anakin saves Obi-Wan twice, whips the shit out of a powerful Sith Lord, ex-Jedi Master who kicked the shit out of Obi-Wan twice, and saves the Chancellor of the Republic from what could've been death. I'm not saying he should've been promoted to master but they definitely should not have asked him to spy on a father figure. Anakin needed to have some respect from his superiors...and I'm not talking Obi-Wan.
