how do other biblical texts, like proverbs or jesus' parables, address responsibility for harm?

Proverbs 28:13

“He who conceals his sins doesn’t prosper, but whoever confesses and renounces them finds mercy.”

This proverb, like many others in the book of Proverbs, offers practical wisdom for living a good and flourishing life. It was written for young people in ancient Israel, likely by various authors over centuries, to guide them in making wise choices and understanding the consequences of their actions.

What does 'renouncing' one's actions look like in practice today?
