There are so many that are quick to pass judgement. And not visit the plank in their eye. It is something that has been going on since the beginning of time. What God ask us to do, is to be mindful of such a thing, because ultimately in the end we are all going to be judged by our very works. Works meaning the things that we do or have done. We are human, we make mistakes. The key is to understand that you do. Forgive yourself, know and trust in your heart that ill will and ugliness was not the intention. A wounded animal is more dangerous then one that isn't. Think about the other person. When they lash out, they may be hurting. Understanding and wisdom are much more precious then gold. Use yours.
In your anger do not sin": Do not let the sun go down while you are still angry, and do not give the devil a foothold. He who has been stealing must steal no longer, but must work, doing something useful with his own hands, that he may have something to share with those in need. Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen. And do not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption. Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice.
