Answer:
Cheating in the card game at the end of the novel presents the picture of corruption and evil in the political system. The pigs and the humans both were indulged in the same type of corruption and cheating in the card game. This exemplifies the strength of the political power. Whether it be a human or a pig, the nature of the politician changes with respect to that of the power. Mr. Pilkington and Napoleon entered a heated argument in which both of them tried to cheat in the similar way. This brings to the conclusion that both the pigs and the humans played the role of liars, manipulators and hypocrites when the question of politics and humanities were asked.
