Criminal negligence is the gross and culpable neglect or failure to exercise that reasonable and proper care and precaution to guard against injury either to the public generally or to an individual in particular, which having regard to all the circumstances, out of which the charge has arisen, it was the imperative duty of the accused person to have adopted.

Rashness is doing an act with utter indifference to the consequences of which the doer may be conscious and which he hopes may not take place. In other words, rashness concerns of hazarding a dangerous or want on act with the knowledge that it is so but with the hope that it may not cause injury.
