Do you have anything of substance to say or are you just mocking the character for the sake of it? Zoro joined Luffy reluctantly, and he has a conflicting personality that doesn't allow him to be a follower. He was someone who put his goal over any and everything before joining the crew. He is someone who'd never put aside his values and preferred losing his life over compromising them.
All of that changed over time. He became a loyal follower who takes orders without talking back. He set aside his values for the sake of his crew and bowed down to his enemy to get stronger so he can better protect his crew. He now puts Luffy's goal over his own. He totally doesn't mind throwing his life and goal away for not just Luffy but any given crew member. The other SHs went through some changes over time but none of them changed as drastically as Zoro.
