I had amoebic dysentery once and it is horrible to try to kill. ...You have to take a nasty drug that causes all sorts of nasty side effects. And it stays in your system until you kill it.
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.
Inseparable from any definition of satire is its corrective purpose, expressed through a critical mode which ridicules or otherwise attacks those conditions needing reformation in the opinion of the satirist. I believe there is no satire without this corrective purpose. Accordingly, the best definitions of satire should be formulated from a combination of its corrective intent and its literary method of execution.
