How did god punished Bishop Hatto?

God punished Bishop Hatto by sending a swarm of rats to consume him after he had cruelly deceived and betrayed the poor during a time of famine. According to the legend, he had locked the starving people out of his castle, only to face divine retribution when the rats, drawn by his greed, swarmed in and ultimately devoured him. This tale serves as a moral lesson against greed and the consequences of inhumanity.
