Question

How are satire and sarcasm different?

Answer 1

Sarcasm is intended to hurt or mock someone by implying or saying comments  that have a different meaning from what they literally mean. Satire serves a similar purpose, the difference relies on the fact that satire is more associated with politics. It tends to decry and expose the corruption, injustice and mistakes of a kingdom or government.

Answer 2

Sarcasm happens when the writer or the speaker utter something to mean exactly the opposite in order to make the audience or listener feel uncomfortable.  On the contrary, satire is generally used for political purposes in order to expose people's stupidity by using humour and exaggeration.
