"Worse than pigs and dogs" is a highly derogatory idiom. Its literal meaning is "even worse than pigs and dogs," and it is used to describe a person whose moral character is extremely base and despicable, who has lost all humanity, and who is even inferior to beasts. In traditional culture, pigs and dogs are often regarded as lowly, filthy, and stupid animals. Therefore, using "worse than pigs and dogs" to insult someone is an extreme form of humiliation and condemnation. This idiom comes from A Dream of Red Mansions, where it is used to criticize those who are morally corrupt and behave wickedly. It is mostly used to accuse someone of committing outrageous, treacherous, and conscience-less acts, such as abusing one's parents, betraying friends, or harming innocent people. Its emotional tone is extremely negative, carrying intense anger, contempt, and repudiation. In terms of cultural background, it reflects the demand of traditional morality for the bottom line of human nature, namely that humans should be different from beasts; if a person's behavior is worse than that of beasts, then that person has lost the qualification to be human. It should be noted that this idiom is extremely insulting and should be used with caution in daily communication to avoid causing serious conflict.
