that was not what I meant...I meant it was stupid way of intrepreting things...leaders won't take all decisions randomly...they have well wishers and intellectual advisors who give advice when leader doesn't find a way...it is upto the leader to take final decision.....it doesn't mean that that advisor "taught" him to be leader....that was the case here....
luffy was thinking the straw hats are just best friends on a journey, that's why he was willing to forgive ussop right away, hell , everyone on the crew thought the same untill zoro stepped up, he explained that luffy is more than just a friend, he's a captain and a captain must command respect for the sake of himself and his crew. in thriller bark kuma is impressed that luffy could command the respect of men like zoro and sanji. so did uroge in sabody.
it's simple stuff really.
