In culpable homicide cases, while personal mitigating circumstances of an accused (first offender status, guilty plea, time in remand, age) must be considered, these must be balanced against the circumstances of the offence and the interests of society. The use of a specified lethal weapon (okapi knife) in circumstances involving trivial provocation (an argument over a ball tackle) constitutes severe aggravation, particularly where: (1) carrying such a weapon is itself an offence; (2) no physical force was warranted; (3) a vulnerable and vital area of the body was targeted; and (4) the victim was killed for no justifiable reason. Courts must impose sentences that send a strong deterrent message against carrying lethal weapons and using violence to resolve disagreements, and must demonstrate society's disapproval of unnecessary loss of life.
