Ah, I finally noticed this discussion so I can toss in my 2 cents. lol
I love anti-villains and anti-heroes. It blurs the line between good and evil and often makes stories much more interesting than those with generic protagonists and antagonists. Characters have more depth imho and you can see the villains are better than the typical selfish pricks just as the heroes aren't the selfless saviours we are used to from most stories. I have to say it is quite satisfying to be the only Sith in a thread, yet come off as the "good guy" when compared to the rest.
So, since some people want to roleplay a Jedi anti-hero, I thought I'd share my opinion on that. There is nothing wrong with it, but one should keep in mind they still roleplay a Jedi. Some people go all out with the "dark" aspect and slip over the edge. Torturing innocent civilians for fun, for example, does not make one an anti-hero. It makes one a villain. I understand the wish to portray the darker side of a "good" guy, but behaving worse than Sith really kills the point of roleplaying a Jedi in my opinion. In fact, it makes many Sith look like the good guys.
This brings me to anti-villains. Oh yeah. I love those. My Sith is one. Villains with principles, morals, that kind of thing. So much fun to roleplay! Anti-heroes do a really great job at making him look like a legitimate good guy. Some people complained my Sith is not evil enough... well, he isn't meant to be. Evil evil villains who do evil for the sake of evil are not my thing. They are boring to me, unfortunately, so to even try the Sith out, I had to come with the concept of a "good" Sith who sees the Republic as a corrupt fascist regime and Jedi as unethical power-hungry hypocrites. Some Jedi characters actually make it quite easy to portray the Pubs like that :lol: And yes, he's still an anti-villain, as he wants to exterminate a few cultures to build a better world.
