What Is the Difference Between an Act of Omission and the Commission of an Act?

An instance showing the difference between an act of omission and the commission of an act is the difference in withholding the truth and voicing a lie. Both an act committed and an act of omission can change the result of a circumstance.

An act of omission and an act of commission are ethical issues of both a secular and religious nature. There is a difference in moral theology between formal cooperation and material cooperation both with and without consent. When a person either aids in an evil act or does nothing to prevent that act, it is cooperation with evil.
