someone posted this on another board and I thought it was an intersting take....

My reasoning is that Anakin believes that Padme is going to die. He believes that because he had the same visions in Episode II, only they were about his mother and she died. He couldn't do anything to save her.

The Jedi, through Yoda, pretty much tell him that they have no way to prevent Padme's death.

Palpatine tells him that he has a way.

But why is Padme so important to Anakin? Anakin had no father. He was separated from his mother when he was ten. At the same time, she first met Padme, who was older than he was. Padme becomes a mother figure to Anakin.

And she's hot...

Now, let's examine the Jedi situation.

The Jedi Council's first examination of Anakin must have been pretty stressful for the boy. He's ten years old. Away from home. He has just left his mother, because he was promised that he would becoem a Jedi. And a bunch of old men he doesn't know tell him that he will not be trained after all.

Ultimately he's accepted in the order but the order never trusts him. He was too old to begin training, his future is clouded, "I sense much fear in you", whatever...

At the same time, Palpatine shows him trust and acceptance and builds up his ego. Little orphan Ani (sorry...) finds a cool father figure. After all, he is the President of the universe. How cool isthat? Obi-Wan, on the other hand is too busy scolding him, since that's what mentors must do and not telling him that he loves him, since that's not what the Jedi do.

Coming back to Padme, Anakin is horny, since he's twenty years old and a virgin, despite looking like a member of a boyband. Padme is also his freudian substitute mom. Problem is that the Jedi are not big on sex and commitment.

A pattern is beginning to emerge...

Finally, the sith hits the fan, when Anakin realises that the other Jedi, which he thought that they were more pious than he was, are a tad hypocritical. And Anankin was bee nshow to feel guilty for not following the Jedi code to the letter. The Council has no problem asking Anakin to spy on his uncle Palpatine and they have no problem turning Palpatine into a shish kebab, later on, when he is revealed to be a Sith lord. Despite being unarmed and looking like a California raisin with a toupee.

Of course, Anakin fails to realise that there is a big difference between doing those things in order to stop a war and save the lives of thousands of beings and democracy and doing them because you want to bang Natalie Portman and avenge the guy who chopped off your arm.

So, from his point of view, a hypocritical asshole Jedi is going to kill the only man who's ever told him what a great guy he is, instead of holding him at an arm's length. And if he kills him, his pregnant wife, which he is attached to since childhood, is going to die and there will be no way to stop this.

Anakin only has seconds to think before acting and Anakin was known for severing limbs first and asking questions later.

After becoming an accomplice to his boss' murder he can either try to arrest or kill Palpatine, meaning that the death of Mace would've been in vain, or convince himself that he did the right thing and dedicate himself to saving his wife's life.

He basically has to chose between "you can't make an omelette, without breaking some eggs" and "I'm a murdering idiot".
