The Bible tells us to avoid sarcasm, calling it sharp-tongued as well in the process. And it is. It’s not a nice character point and one that should be avoided.
Sarcasm is ultimately about putting other people down and making cheap laughs at their expense.
What you normally find is that sarcastic people love it when the joke is on another. But not so when they’re the focus of someone else’s sarcasm
