Nothing in that statute about "assault" or "violent injury" being necessary to resort to lethal self-defense. And yes, facing someone brandishing a firearm after chasing you down does produce a reasonable fear of "imminent use of unlawful force."
You pretty much ignored the entire statute.
"A person is justified in threatening or
using force against another when and to the extent that he or she
reasonably believes that such threat or force is necessary to defend himself or herself or a third person against such
other's imminent use of unlawful force;
What force did Arbery use? What imminent use of force did McMichael employ?
"a person is justified in using force which is intended or likely to cause death or great bodily harm only if he or she reasonably believes that such force is necessary to prevent death or great bodily injury to himself"
Arbery's act of running at McMichael and trying to take his gun by punching him is not consistent with the actions of one who reasonably believes that doing so is necessary to prevent death or great bodily injury. In fact, it's just the opposite.
