Here we go again with the absolute statements. "wrong", you say, and when I suggest that this is a matter of interpretation I have little doubt that you will tell me that it isn't a matter of opinion or interpretation. In fact you say here it is "according to Lucas", but forget that the quote that you are using to shore that position up is but one of many. Other quotes suggest that how you claim it to be is questionable (and are less confused in their context). And, who is this "certain Force Wielder" that you speak of? It seems strange to be coy about such. Do you mean Palpatine? In a scene where he is trying to turn Anakin? The term "darkside of the Force" is only used by Sith characters. Given that the films are (according to Lucas) about choices, then it makes sense to understand the difference between the Sith and the Jedi in terms of how they use the Force - and it is, I think, telling that the Jedi never use the term "lightside" and only ever talk of the use of the Force. Lucas was pretty categorical that Anakin Skywalker brought balance to the Force by destroying the Sith and ridding the galaxy of evil, so I don't understand how that fits in with the idea that the Force is in balance only with an equal power between this notional darkside vs lightside.
