The role of satire is to ridicule or criticize those vices in the society, which the writer considers a threat to civilization. The writer considers it his obligation to expose these vices for the betterment of humanity. Therefore, the function of satire is not to make others laugh at persons or ideas they make fun of.
1 Satire is witty, ironic, and often exaggerated. It uses extremes to bring its audience to a renewed awareness of its ethical and spiritual danger.  Sometime if the satirist is in danger for his or her attack, ambiguity, innuendo and understatement can be used to help protect its author.
