Proverb 17

Bitter conflict, discord, antagonism; who wants any of THAT?

Less is better when strife is absent. Strife kills relationships, breeds wars, makes life miserable. We are wise to avoid it.

Where there is strife, there is pride (and arrogance), but wisdom is found in those who take advice. [Pr. 13:10 NIV]

Expel the arrogant and discord goes too; strife and insult cease. [Pr. 22:10 NABRE]

This is a big reason why pride and arrogance need to be driven OUT of children. If they continue in it, their life will be a constant struggle (for themselves and others).
