Although there are two offences , murder and manslaughter , the latter includes two distinct varieties : ‘ voluntary ’ manslaughter ( killings which would be murder but for the existence of defined extenuating circumstances ) ; and ‘ involuntary ’ manslaughter ( killings for which there is no need to prove any awareness of the risk of death being caused , but for which there is thought to be sufficient fault to justify criminal liability ) .
