Why do people die and then, come back to life in satires?

In a realistic novel like realistic fiction, a biography, and even historical fiction, characters do not die and come back to life.  This decisions by the author is to make the story believably and relatable by the basic rules of life.  For me, if I can relate to the story agin any way including at the plot follows basic rules of nature (if someone dies, they do not live again), I am more attached to the characters and the plot.  With some stories, I will be so attached that I will cry when someone dies or something goes wrong or I will be happy all day when something in the story goes the way I want it to.  One major difference between one of these kinds of stories and a satire is that these stories are trying to explain or express a part of life (this familiarity makes theme he stories relatable and the readers emotionally involved); a satire tries to make fun of life and having people dying and then living again takes people out of emotional ties with the characters and plot.  Not being affected by characters and their actions pushes readers away from emotional ties with characters.  This relation between reader and character guides the reader to take a step back from the story and look at the entire picture which is what a satire's aim is except with a funny twist on the the message.
