That would make some sense. Arthur seems to be naturally inclined to doubt himself. His self-esteem about the vigilante business can't be great in the first place given how much he gets beaten up, even though he wins. An actual decisive loss could make him decide "boy I'm shit at this superhero thing" and quit for a bit, which in turn could lead to returning to academia just out of being unsure of where to go next.
