The DS never made much sense to me. Just because one is prone to anger and does some bad things, doesn't mean they're able to become murderous, power hungry monsters, at least not by RL standards. When the Emperor was trying to convert Luke, there really didn't seem like any chance of Luke converting to me. Why would he? He's not a murderous asshole and doesn't crave power. Never at any point was I concerned about Luke turning. Meow, this got me to thinking (and seems so obvious as I type this): It seems in the SW universe the DS works exactly like the one ring in LOTR or an addictive drug in RL. It's like heroin or something--some people use and get clean but it's a dangerous game that often leads to one sucking dick for more. Or maybe that's crack or meth. Whatever. Anyway, the more you use it, the more it corrupts you. It's not like RL where people can be varying degrees of bad but still overall be good, it's not a personality thing. The force itself is a substance and the force sensitive is the user; the substance the user imbibes determines their behavior and health outcome. It's the only way that the DS can make sense. In LOTR, Frodo can wear and even use the ring, but it slowly rots him, and it acts faster or slower depending on the user. Eventually everyone becomes a slave to its power, power being a drug. This is exactly the same with the DS. The Sith think they're free because they don't lead the strict, ascetic lifestyle of the Jedi but in fact they're only slaves, slaves to power. They project their flaws onto the Jedi. The Jedi, by contrast, hamstring themselves by not learning more about the DS. They correctly understand the dangers of it and that not having control of one's emotional state can lead to a conversion, but by being so prohibitive about their knowledge and expression they weaken their own ranks and undermine their own cause, as knowledge, particularly in this case, ironically, is power, power over themselves. That, and the bureaucracy and politics of the Jedi Order have shown to be short sighted. The Knights of the Old Republic video games did a fantastic job of deconstructing and exploring the lore. Thoughts? Is the force a substance? If so, what would the Light & Dark sides be? Dark I think would be hard drugs, light would be weed and mushrooms. Of course there's all manner of metaphor, regardless. There's probably some nerds who have figured this out already or maybe Lucas laid it out in an interview, but whatevs, this is my take. Just spitballing here.
