teach someone a lesson

Make them regret

To teach someone a lesson is to punish or retaliate against them in a way meant to change their future behavior: After he cheated me, I reported him to teach him a lesson.

The phrase implies the target deserves correction and will remember the consequences.

It can describe deliberate punishment or events that humble someone naturally: That loss taught them a lesson about overconfidence.
