Prime Clone
Super Freak
It makes sense and works perfectly for me.
We saw Anakin struggling more and more with his fears and emotions throughout the prequels, and then he was finally pushed beyond his breaking point. Once he attacks Windu he realises he is lost and cannot go back ("what have I done"), and thus surrenders himself to the Dark Side ("I will do whatever you ask").
Exactly. And he does it hoping to save Padme, so there's an end to his means.
He's still conflicted, both then and throughout the OT (as Luke points out).
