Don’t be excessively righteous, and don’t be overly wise. Why should you destroy yourself? Don’t be excessively wicked, and don’t be foolish. Why should you die before your time?

But Jesus said to them, “You are the ones who justify yourselves in men’s eyes, but God knows your hearts. For what is highly prized among men is utterly detestable in God’s sight. 

(Luke 16:15 NET)
