"Do not think that you are more righteous than you actually are"

Why should you destroy yourself?

The writer uses this rhetorical question to emphasize that being self-righteous destroys a person. Alternate translation: "There is no reason to destroy yourself." or "If you think this way you will destroy yourself." (See: rc://en/ta/man/jit/figs-rquestion)
