When I asked this question in the irc chan, I got flamed. Frankly, that was rather disappointing, seeing as how this is a legitimate question about translational differences. Thanks to the two people who said go ahead and post it up here anyway and ask.

In episodes 129-134, AonE translates the backstory of the Uchiha clan as particularly dark and menacing. You get the distinct impression that they're plotting something and perhaps Itatchi killed them all to spare himself and Sasuke from whatever they were doing.

This, however, is in dire contrast to other fansubs which don't quite paint the clan in such a dark tone.

So the question stands, why choose this particular translation? Frankly, I like this translation. I'd love, though, to hear an in-depth discussion of why it was chosen over the more pedestrian translations used by other groups.
