They didn't explore the emotional state of Rolf and the others nearly as much as they should have (or, really, at all) after Nei's demise. It was just, basically, "oh well (shrug) let's go close the dams". Why? I mean, Rolf was just continuing to work after Climatrol and trying to fix Motavia, but what about his feelings? His emotions? You saw it with Chaz for sure.
Megid comes from anger (though this is not, to my knowledge, explicitly stated in PS2, but only PS3/PS4), but Rolf's anger isn't explored for the most part.
I don't know, I'm just rambling at this point, but I'm sure you guys know what I mean.
