Things that Are Murder Webster defined murder as The act of unlawfully killing a human being with premeditated malice, by a person of sound mind. We know this definition, which is almost universally accepted. But, the Bible talks about murder in other areas. Notice that the Bible does not say being angry. It is being angry without a cause which is murder.
Justified anger has a solution.
Either the offender admits guilt and makes restitution or the offended grants forgiveness, or both. Anger without a cause has no solution. Ultimately it finds an expression which is always negative. It may express itself in character assassination, or random violence, or even actual murder. Because it is the root of murder, it is murder.
