Understanding this concept is crucial as it separates the mere intention to commit a crime (which relates to "mens rea," or the mental state) from the actual behavior that results in criminal liability. For a defendant to be found guilty, there must be evidence of both the actus reus and the mens rea surrounding the crime.
