Modern crimes codes in the United States usually make distinct four degrees of culpability.
Legal definitions are:
1.) A person acts intentionally with respect to a material element of an offence when:
if the element involves the nature of his conduct or a result thereof, it is his conscious object to engage in conduct of that nature or to cause such a result; and
if the element involves the attendant circumstances, he is aware of the existence of such circumstances or he believes or hopes that they exist.
2.) A person acts knowingly with respect to a material element of an offense when:
if the element involves the nature of his conduct or the attendant circumstances, he is aware that his conduct is of that nature or that such circumstances exist; and
if the element involves a result of his conduct, he is aware that it is practically certain that his conduct will cause such a result.
3.) A person acts recklessly with respect to a material element of an offense when he consciously disregards a substantial and unjustifiable risk that the material element exists or will result from his conduct. The risk must be of such a nature and degree that, considering the nature and intent of the actor's conduct and the circumstances known to him, its disregard involves a gross deviation from the standard of conduct that a reasonable person would observe in the actor's situation.
4.) A person acts negligently with respect to a material element of an offense when he should be aware of a substantial and unjustifiable risk that the material element exists or will result from his conduct. The risk must be of such a nature and degree that the actor's failure to perceive it, considering the nature and intent of his conduct and the circumstances known to him, involves a gross deviation from the standard of care that a reasonable person would observe in the actor's situation.
