What's Stopping These Non-Moody People From Doing It?

As a society, we are more accepting of those handicaps and moodiness because they're completely out of the person's control. A blind guy could sit there staring at that eye chart on the wall six hours a day for five years, he's never going o be able to read that giant e on the top line is it's not happening. Even if we accept all these premises, i don't think moody people are evil or something. I mean, in keeping with most patterns of human behaviour, i generally think that people do things ecause, at least at the time, they think it will improve their situation.
