Hurting another is hurting God.

You must do all that is possible to support the growth of another human being. If you are a physician, you take an oath to help others. If you know God, you must take an oath to help others, for any knowledge of God in life is associated with a contract between you and God related to your dealings and your sensitivity to others. You would not knowingly hurt God, therefore you should not knowingly hurt another.

Certainly there are mistakes which are made. There are times when you speak out and then wish that you could retract what you said. That is normal and one should not be ashamed of those instances. You should, however, learn from them—learn about the power of words and thoughts and their effects on others.
