Depravity of mind refers to the state of mind which is contrary to justice, honesty or morality. Depravity of mind is a condition where there is a deviation or departure from the ordinary standards of honest, good morals, justice, or ethics as to be shocking to the moral sense of the society. Depravity of mind can also be described as an act of baseness, vileness, or depravity in the private and social duties which a person owes to another, or to a community.
In the area of legal ethics, offenses that involve depravity of mind such as fraud or breach of trust, make a person unfit to practice law. In Military law, an act involving depravity of mind is punishable, usually with a dishonorable discharge or confinement not less than a year.
