I just recently played through FFIV. I think Cecil was pretty even keel, aside from being upset that he was complicit in the slaughter of a village of innocents, or that the kingdom he fought for was going insane and turning completely evil, or that the woman he loved was stolen away from him by his best friend's turning his back on him and fighting alongside the enemy for no discernible reason, and of course the onset of a world-ending calamity. What I'm getting at here is that he had every reason and right to be a bit down about things. And he never fell into an "emo coma". He got to feeling a bit helpless while visiting a village that he, not a couple weeks prior, invaded and robbed of its most treasured possession. Dude did some bad shit for bad people and felt bad for doing it. There is nothing wrong with that. In fact, it's more consistent characterization than most characters receive in those sorts of situations.
