It's true that as early as AOTC Annie was not a nice guy. You might understand him killing some Tuskens after his mother's death (though it would be risking a turn to the dark side if he did it out of anger), but killing Tusken KIDS is something else entirely. That shows he wasn't a good guy, as does his support for dictatorship. In the OT Lucas gave us the impression that Anakin was a good guy who got turned evil. Clearly he revised that part of the story for the PT when he turned Annie into an asshole who became more of an asshole.

i believe it was Obi-Wan telling us about anakin in the OT. Anikan never told Obi-Wan about the event with the tuskens. so Obi-Wan said Anakin was a good man even though he didn't hear about the tusken slaughter.
