I'm speaking theoretically.Not sure what you are actually referencing here, or referring to, but that's not how self-defense is determined.
An example, you arrive home, in your driveway and you are confronted by an attacker with a knife a few meters away from you, if you have a firearm in your possession you are within your right to use deadly force as in self-defense, furthermore even if it was a pickaxe, shovel etc.
In today's courts there are many shades of self-defense, from one jurisdiction to another... and even arbitrary decision-making where citizens have failed to maintain moral clarity from one generation to the next.
To me, disproportionate force is immoral and should be illegal.
You can say this area is what is known as 'the continuum problem'. It has been debated for a long time. Where there are no hard clear boundaries.
But multiple, competing jurisdictions is the answer to that supposedly unsolvable riddle.
Over time, with many openly competing rule-sets, we will all see which one works and which ones don't.
p.s. if you point your gun at a guy with a knife, standing a few meters from you, you are about to find out if you can use it.... how? By watching his response.
If he runs towards you he has escalated the immediacy of the mortal threat. You would have no trouble finding a jury to back you in that case. (in jurisdictions that still use a jury system, ofc... RSA isn't one of those).
