"This is certainly the reason for the enormous popularity of spectator sports, such as soccer, baseball, and boxing: the contenders are two teams or individuals, clearly distinct and identifiable, and at the end of the match, there are vanquished and victors. If the result is a draw, the spectators feel defrauded and disappointed. At the more or less unconscious level, he wanted winners and losers, which he identified with the good guys and bad guys, respectively, because the good guys must prevail, otherwise the world would be subverted."
