Just to make things clear before anyone answers, if your ONLY reply to this topic is going to be pointing out that the morality system sucks, don't bother posting unless you're planning to follow it up with some constructive thoughts and ideas.
On to the topic.
So you character just happened to drop below 30 morality, despite not really going out of their way to do evil stuff, but maybe just spending a little too many dark side pips. Now dark side pips are their standard force power fuel, and as such, regardless of why they're used, Conflict will start adding up at quite an accelerated rate. You character is still not doing evil stuff as such. He's generally quite a nice guy (or at least not terrible), despite his morality plunging down through the single digits.
How would you approach this from an in-game role-playing perspective? Should the GM act a bit as the devil on his shoulder, encouraging him to give into his darker emotions? As he flips a destiny point to the dark side each session, maybe take that and run with it describe his dark side use as, if not malevolent, just wrong, perverting the natural order of things?
Maybe a character shouldn't be able to cross to the dark side without really "earning it" through his actions, instead ending up stuck at 30?
What are your thoughts?
