On one hand, i can understand Usopps behaviour to a certain point. On the other hand, it STILL irks me how even after the timeskip he apperantly lacks some kind of conviction and sense of duty / honor. He already showed at least some progress in the past, like when he challenged Luffy in Water 7 over the ownership of their ship. Hell, even as early as in the Arlong-Arc he showed more balls then that. Remember when he fought a fishmen 1 on 1 and got his ass handed to him? He planned on pretending to be dead and then go back all like "ah, sorry guys, i lost, well waddaya know, thats so like me". But the moment he realized how the others bet their live on the line, he throw that thought away and went all "come at me bro" with the fishmen!
I am ok with him still beeing a bit of a coward, but i thought we would be past the point where it would be acceptable for him to slander / defame the dream and ambition of a friend, even if its with a lie he doesnt mean for real. I dont demand Zolo-like levels of commitment, but damn, at this point every other crewmember seems to be ready to die for their conviction. So please, after teasing us in the beginning after the timeskip, let Usopp finally man up for real!
