I never hated Rossiu. He was the only realistic guy in the entire show, giving serious thought into it without screaming and kicking people's asses.
Don't get me wrong, I still loved the screaming and the ass-kicking, but I just couldn't hate Rossiu for being smart.
That, and I expected him to do something like that guy from that was in the Simpsons for one episode and went crazy because he was the one one who was normal.
"Hey, look at me! I can pilot a huge robot, because I'm Simon! I can fight a huge amount of enemies, because I'm Simon! I'm going to kick reason to the curb and not die, because I'm Si-*DEAD*"
