I also think there's hope for Solo. As I mentioned a few pages ago he's one of the lost souls of the star wars series, like Anakin and Luke. The lost souls bring balance to the force because they see things from both the light and the dark side. On a related/unrelated note, I was kind of hoping we'd see Luke rocking black like in ROTJ, but Lucas and this whole Sith nonsense has made it so only the bad guys wear black. If Luke would have been wearing black everyone would have said he was a Sith Lord. That was one of my favorite things about ROTJ Luke, he was this tormented Jedi on the edge of light and dark. But perhaps that's why we don't see him in black anymore, because after the events of Jedi he chose the light, so now he's embraced that Old Ben aesthetic.
Watching the Clone Wars on netflix has made me realize the Jedi are a militant cult masquerading as peacekeepers. The lines between good and evil are blurred. Lucas really missed an opportunity to play that up in the movies. The films portray Anakin as a whiny teenager full of misdirected anger, but actually he was a battle-hardened soldier at odds with his own ideologies and those of his religion -- at odds with himself, the decisions he'd made and the ones thrust upon him. Born into slavery, taken from his mother when he was a child, and then only reunited to watch her die. Not an easy life.
Anakin never signed up to be a soldier, none of the Jedi did. He just wanted to protect those he cared about. He never really believed the extremist dogma of the Jedi order, and honestly I'd be questioning the whole thing too. I mean, that's why the Jedi Council didn't want Anakin to train as a Jedi, because he was old enough to see past their ********. The Jedi usually started training before the child was old enough to think for himself, so that the Jedi dogma can be fully indoctrinated without question. If Anakin's anger, which was completely justified, would have been expressed in complex ways instead of outbursts of generalized angst we would have related to him a lot more. Too bad Lucas doesn't understand human emotion.
