Additionally, though it is an incredibly tough (thought not impossible) position to take and defend in court, person A can illegally assault person B, get physically pummled by B, and then shoot them in self defense. You can't make a "Stand your Ground" argument (and be shielded from civil liability) but you can make a justifiable homicide criminal defense (think joe schmo attacks someone who holds 9th degree black belt in 15 different arts and the black belt won't stop hitting him after joe is defeseless with debilitating injuries).
You will have to cite some cases to prove this point you are trying to make. In most instances, if A starts a fight with B and B pummels A within an inch of their life, A cannot claim self-defense when A was the aggressor. If A did not want to lose the fight, A should not have started it, and I am sure most juries would see it the same way too.
