Sorry, but no.
The shooter acting in self defense does not need to explain anything to anyone except to give his or her attorney the facts. Because is the prosecutor's burden of proving it was not self-defense. It's prima facia self-defense.
Self-defense is a complete defense to murder.
"Headshots" you're either a good shot and meant to do that (which a prosecutor could use to charge you after the fact depending on the facts, or it was just a shot out of fear that happend to hit the head, it can show premeditation and deliberation - but again self defense is a perfect defense for murder)
"If you execute" now you've introduced assumptions into the facts and speculation that is was a murder rather than self-defense. Anyhow, there is no black letter law that states you can't shoot someone that is on the ground in a pool of their own blood. There are cases where that was found to not be believeable but that's a case by case basis.
If someone is on the ground bleeding - THEY CAN STILL REACH FOR A WEAPON OR CAUSE SOMEONE INJURY (kick, claw, bite, etc) - therefore someone defending themselves or merely believing they are still in danger may continue to shoot.
There is no text in a law reading in part to convey a person's actions such as shooting fast, shooting slow, somoene still standing, etc.
you do it your way, I won't argue.
I still stand by my belief that if you're in court arguing why you shot an unconscious man in the head twice because he "might" have reached for a gun that landed 2 feet away and was covered in blood spatter from shots #2 theu #9, I'm thinkng it's going to be a very long day in court.
You shoot until you no longer feel the person is a threat to commit a forcible felony. me, I don't want to have to explain to a jury full of soccer moms why I truly believed the man with three holes in his belly screaming and 2 feet from his gun needed me to stand over him and aim at his temple and pull the trigger. Personally, I shoot until I no longer feel threatened, and I exit that MFer. by the time the bad guy has 3 bullets in his torso, I'm hoping I'l already out the back door calling 911. let the bad guy decide if he wants to crawl after me.
