Well, now that we know Accelerator isn't a complete psycho, a Touma Fraction could really become powerful. I'm trying to figure out if he was simply acting psychotic/crazed, or whether he was really like that until his defeat lead to some introverted thinking.
Reason being that he's wondering what's changed as people are attacking him. To the audience, it's obvious that it's because he no longer looks like he'll rip someone's dick off or something if they look at him the wrong way.
