@Silence:
Anyone trying to say Zoro is more insubordinate to Luffy than Usopp has been curiously absent for the last 100 chapters. I love how people ignore circumstances on this forum to forward their own theories.
Since you opened your own can of worms, Buddy, please explain to me how your theory of Usopp's "insubordination" is somehow worse than what Nico Robin almost tried to pull– she basically gave up not only on the entire Mugiwara Crew, but also on herself by wishing to die. Not to mention her dying mother's last wish for Robin to 'live', and the whole team of archeologists who supported Olvia as well.
Usopp merely followed his own convictions to keep his treasure, the Going-Merry-- and went as far as challenging his best friend Luffy for his beliefs. If you call him a coward for this behavior, it's a little foolish (and quite sexist) to avoid calling Nico Robin a coward as well for almost going through with suicide without even trusting in the Mugiwara Pirates to help her fight against her past demons.
For the record-- Usopp never ran away. After he 'quit', he came back on his own as Sogeking, but he still ended up fighting alongside his crew when they needed him. Robin needed to be convinced by ALL of the crew before she made the resolve to fight. The people who are ganging up against Usopp for essentially staying true to the characterisation Oda set him up with since his introduction (the liar, the sneak, but when push-comes-to-shove the guy you can depend on to be there for his friends) are being shortsighted.
It's entirely in Sogeking's character to bawl like a baby and beg to be let back on the crew after trying to con his way back on like nothing happened. That's sorta who Usopp is-- he's still that kid who was orphaned back when his mother died from illness while waiting in vain for Yasopp to return home from his pirate life. You gotta take a step back and realize how helpless a person would feel in that situation. I'm sure Usopp felt like the same thing was happening all over again when he suddenly realized that Luffy might not take him back as the crew's sniper, so yeah, he got desperate and clung to the family that he made (and just helped keep together during the EL battles) with the Straw Hats. I clearly saw the symbolic act of him crying over the potential loss of his new family, when thinking back on how his first one was demolished. You clearly did not.
Along with Nami, he's the only person who's not really battle-trained (actually, Nami's been trained to use the bo-staff, so basically Usopp is the least combat-trained-- and he's regularly going up against Devil Fruit users with multi-million bounties on their heads and you people have the gonads to call him a coward?!)
Creating Sogeking was obviously Usopp's way to negotiate him feeling powerless and useless to the crew. With his 'superpowers,' (which are really just Usopp's great tactics and invention skills) he uses the Sogeking persona to gain the confidence that he never really had growing up as a kid. Him bawling and crying to be let back into the Straw Hats crew I still can't get past as it's oh-so-clearly Usopp realizing for the first time that he is part of a real family, like the one that he lost in his childhood. It wasn't pathetic at all, it was one of the most heartwarming scenes in the entire series. Figures a bunch of immature kiddies can't see something simple as that.
This ends my fanboyish rant.
