A common triadic complement used to combat Arrogance or Hatefulness is the secondary virtues of Humble or Teachable, and Honest or Realistic.
When we tend towards arrogance, which is taking virtue or being principled too far, it is helpful to apply the combination of humility-–recognizing that we do not know everything—and honesty—an understanding of our true condition—to counter arrogance or hatefulness.
