I am not sure just saying or thinking that you feared death or grievous harm would be enough in all cases from what I can read.
In such cases, juries are supposed to be instructed to view the circumstances as if they were the defendant. It's called the "reasonable man" test, and it calls on the jury to answer the question: What would a hypothetical reasonable man have done if he were in the same situation?
The jury instructions also tell the jury (or are supposed to) that they are to ignore facts that were not known to the victim ("victim" being the person who was assaulted and used deadly force to protect himself). In other words, you see a mugger pointing a gun at you, so you draw your gun and shoot him. (As advised by the Dalai Lama.) After the fact, it is discovered that the mugger's gun was a plastic airsoft with the red tip removed from the muzzle. The jury is not allowed to decide that your use of deadly force was excessive, because at the time you could not have known that the mugger's gun wasn't real.
Whether a person sees the punch coming or not, even you acknowledge that a punch can kill, and a punch can certainly cause serious bodily injury. In the case of an assault (as opposed to "consensual combat," wherein two macho men
agree to step outside and settle it "like real men"), anyone in his or her right mind would (or should) fear death or serious bodily injury if assaulted. How can you know the attacker's intent? Too many people have been curb-stomped after being punched to the ground for it to be anything but stupid to think that one should NOT use whatever means he has available to defend himself because "A real man can take a punch."
You never know what you're up against. Example: A long, long time ago I came home from the Army for Christmas leave. I had a 16 hour bus trip, a 2-hour wait, then a 2-hour bus trip, then I had to take a cab from the bus terminal to my parents' home. As I got in the cab, the cabbie asked if I would mind sharing the ride (and the fare) with another man going in the same general direction. This was around 3:00 in the morning and there were no other cabs around, it was cold, so I agreed. The other man's stop was on the way to my destination but, when we got to the neighborhood, the guy couldn't quite remember where he was going. We drove around several blocks, then when the cabbie stopped and asked if anything looked familiar the guy opened the door and bolted.
The cabbie called his dispatcher, who called the cops. The first officer who arrived heard the story, and then said to the cabbie (and I quote), "Jesus, you didn't touch him, did you?" The answer, of course, was no, but I wondered why this had seemed so important.
The cops couldn't find the deadbeat, and eventually they gave up looking. The cabbie was [extremely angry], but not so angry that he took it out on me. As a buck private, I was traveling in uniform because I got cheaper bus fare that way, so he knew I was a soldier. He reset the meter to zero and we went on from there. En route to my home I asked why the cop had made such a big deal out of touching the deadbeat. The cabbie answered that he was a U.S. Marine hand-to-hand combat instructor at the local reserve training center, and that for him to have laid hands on the deadbeat could be construed in court as assault with a deadly weapon. Now, the cabbie was maybe 5'-10" tall, medium build, and rather nondescript in appearance. Not anybody's stereotype of a walking lethal weapon, but apparently that's exactly what he was.
YOU ... CAN'T ... KNOW.
In my view, if you DON'T fear death or serious injury from a physical assault, you're either not sane or you're on drugs. Your view is apparently either more benign, or based on having seen a lot less of real life than I have seen.
