What is a critical consideration before using deadly force for self-defense?

The consideration of ability, opportunity, and jeopardy is critical when evaluating the use of deadly force for self-defense because these three elements determine whether the use of such force is legally justified.

Ability refers to the capacity of the aggressor to cause harm. For deadly force to be justified, the threat posed by the assailant must be capable of causing serious bodily injury or death. Opportunity indicates that the aggressor is in a position to carry out the threat; they must be close enough to the defender to inflict harm. Jeopardy involves the actual or perceived threat to the defender's safety; it implies that the defender is in imminent danger of serious harm.

Together, these components create a standard for assessing whether the use of deadly force is necessary and proportional to the threat faced. If any of these elements are lacking, the justification for using deadly force diminishes. Therefore, understanding these three factors is essential for ensuring that the self-defense claim is legally defensible.
