>>29289975His reasons for staying out ARE pretty solid. Instead of being lazy and not caring like most people from Gens I-IV, he chooses to stay out of the fight because he doesn't know everything about them. He only has the word of one side of the argument (and admittedly, half of Team Plasma has since gone public about trying to atone, making things more complex.) To judge and fight against one side, without knowing enough of what's going on, could lead to trouble.
It was part of the theme of the first BW games; seeing things strictly a black-and-white is bad.
Granted, Marlon's way wasn't necessarily right; while it's a very good stance to take, the issue presented IS black and white, and I believe Hugh gets mad at Marlon because of it.
Marlon does end up helping you sneak onto the Frigate after you beat him. He's still trying to stay out of it, but he's starting to trust you enough to take a stand.
Yes, I know I'm reading waaaay too much into a minor character. But that's kind of how I saw him, and it really made me appreciate him. He's right, but also not.
