Where an accused raises self-defence but the facts show that the means used to avert a perceived attack were not reasonable in the circumstances, self-defence operates at most as a partial defence, reducing murder to culpable homicide. For a murder conviction, the State must prove either dolus directus (direct intent) or dolus eventualis (foresight of death as a likely result coupled with recklessness). In sentencing for culpable homicide, while delay in prosecution and first offender status are mitigating factors, a custodial sentence is warranted where violence leading to unnecessary loss of life demonstrates lack of self-control, even where exceptional personal circumstances exist. Not every case falling within the community service threshold is deserving of community service, particularly where violence could have been avoided.
