Principle 10-1-1
When anger is reasonable
I think so too. There is a real problem here, a carelessness that could have severe consequences. It's hard for me to imagine someone doing this and not feeling angry, maybe even very angry, about what happened.
Sure, the anger may not be very helpful, but it may prompt us to be more careful in the future.
How about this example? A child carelessly drops some of the green beans for his dinner on the floor. The father reacts with intense anger.
Is this intense anger reasonable?
