I think if most people would do an honest self-assesment and "inventory" their anger they would find that about 1-2% of their anger was righteous and justified, and that their anger drove them to take positive actions to right a wrong, overcome an injustice, etc. The other 98-99%, they would find, either spurred them to do something really stupid, or they bottled it up and allowed their own hearts, minds and souls to stew in the poison of their bitterness.
