What considerations dictate the appropriate amount of force used when deploying an improvised weapon for self-defense?

The appropriate amount of force used when deploying an improvised weapon for self-defense is dictated by the principle of proportionality, meaning the force used must be reasonable and necessary to stop the immediate threat. The level of force should be proportionate to the perceived threat; using more force than necessary could lead to legal consequences. Factors to consider include the severity of the threat, the attacker's intent, the attacker's ability, and whether there is a reasonable belief of imminent danger of death or serious bodily harm. The goal is to neutralize the threat, not to inflict unnecessary harm. For example, if an attacker is attempting to punch you, using an improvised weapon to create space and escape might be proportionate, whereas using lethal force would likely not be justified unless the attacker posed a credible threat of death or serious injury. Each situation is unique, and the amount of force used must be judged based on the specific circumstances and a reasonable assessment of the threat.
