It depends on the specific circumstances of the incident and the laws of the jurisdiction in which it occurred. In some jurisdictions, an individual may be allowed to use deadly force in self-defense if they reasonably believed that their life was in danger. However, in other jurisdictions, deadly force may only be used in response to a deadly threat. Additionally, the fact that Frank was initially the aggressor in the altercation may also be taken into account. Ultimately, a court would need to evaluate all the facts and circumstances to determine if Frank is entitled to recover damages from Allen.
