The binding legal principles established are: (1) Where an accused does not intend to kill and does not foresee the possibility of death but uses disproportionate force in response to aggression or threat, the appropriate conviction is culpable homicide based on negligence rather than murder; (2) The use of force that is excessive or disproportionate to the danger posed constitutes negligence in averting danger; (3) In sentencing for culpable homicide, a wholly suspended sentence may be appropriate where extensive mitigating factors (first offender status, guilty plea, contrition, provocation by deceased, family circumstances, unlikely repetition) far outweigh aggravating factors, even though life was lost; (4) The court must balance respect for the sanctity of life with the individual circumstances of the offender and the offence.
