A more interesting way for Anakin to have turned to the Dark Side would have been for him to have experienced powerlessness and suffering during the Clone Wars and wanting to end it. He could have also seen ignorance and incompetence causing pain and prolonging the war.

From this, a desire of order and control could have very easily emerged. It would have been easy for Palpatine to then convince him to support his authoritarian ideals, by simply suggesting that the entire conflict was a result of weakness and an excess of liberty ("We can end this destructive conflict and bring order to the galaxy!"). Then he offers the emotionally crushed Anakin the ways of the Dark Side to medicate his personal sense of powerlessness and weakness. It becomes hypnotising and seductive, and he loses his sense of who he was completely ("You don't know the power of the Dark Side! I must obey my master!").

In this way, Anakin's fall could have been initially driven by an understandable desire to end suffering in the galaxy before it was perverted into a lust for control and power. This would mirror nicely with Luke's desire to end the suffering of his firends in Cloud City and the obvious risk this posed for his training.

(This doesn't happen in the prequels. Anakin's mother's death was not a result of the Clone Wars in Episode II or any political conflict, and therefore couldn't reasonably be taken to have effected him a political way - especially since it is even before his mother's death that he expresses sympathy for fascism.)
