Showing kindness and forgiveness in spite of feeling anger, no matter how righteous, is a sign of unmitigated strength and humility. It is also incredibly difficult to do. 

The majority will judge you as weak for not exacting revenge against your antagonist, even though anger and revenge are typically the path of least resistance.

Kindness is hard, but it's the light in the darkness. Be the spark that spreads love like a wildfire across the world.
