I'm not saying that you should just sit there and get beat up. I'm saying that you should only be aggressive as an absolute last resort, because in the vast majority of cases there are much better options (such as running away, or fighting defensively), that accomplish the exact same outcome without putting the other person in a hospital.
What in the bloody hell is fighting defensively, you can't defend yourself without hurting your attacker unless you're sufficiently scary or you're Jackie Chan in a ladder factory
If you were either one of the two, no one would be picking a fight with you, and most people are not the two
It's like, if someone shoots a gun at you, your first response shouldn't be to open fire with your own gun aiming to kill
Waiting for you to be incapable before defending yourself sounds like telling people to sit there and get beat up
Two wrongs don't make a right, and just because someone punches you doesn't mean that it's suddenly okay for you to punch them back in the eyes of the law.
This is the same thing
The crime that the "helper" or "defender" is committing isn't the one of defending themselves or someone else. It's the crime of defending themselves in a way that is more violent (more "wrong") than was necessary. There's a reason why the burden of proof in justifiable homicide is placed solely on the defendant, it's their job to prove that what they did was the minimum necessary to stop it.
The word I'm looking for to describe what you said is either misguided or malicious; you're trying to get rid of the presumption of innocence, it is in the prosecution's case to prove that the defendant killed whoever and that they killed whoever in unjustifiable circumstances. The burden of proof is not solely placed on the defendant, it is not placed on the defendant at all.
You want to fuck up innocent people as much as possible lol?
Even in states with Stand-your-ground laws (which is not all of them, I might add), you are only allowed to match force for force, and even then it generally includes a line somewhat like this:
[t]he individual honestly and reasonably believes that the use of deadly force is necessary to prevent" the imminent death, great bodily harm, or sexual assault of himself or another individual.
The key here is "is necessary". If you have the option of a less violent way of defending yourself, then the more violent one is no longer "necessary", it's you choosing to be more violent than you have to.
Key word here is necessary, if you have the necessary means, then you are justified
I have the option of running away.
You've never been attacked by someone faster than you, or bicycle mounted gang
I have the option of retreating defensively.
What the hell are you even talking about
I have the option of pushing someone with the intent to disable rather than harm and then running away.
Do you want to die or something hahahahaha
Every single one of these options allows me to stop being beaten up
Every single one of these options will end with you being beaten up
and does not involve significantly harming the aggressor. I'd really like to know what justification you have under which doing more harm than less is somehow "necessary".
Protection of innocents duh, I have no idea what you're talking about as if this is some vidya gaem where you can delete 5 health off your enemy with a special pokymon attack and they'll be incapacitated, but you will never know - all you can know is fight or flight until you are safe, and that's only when your attacker is incapable of hurting you.
When you attack someone else unjustifiably you've broken a basic civil duty to your fellow man that really puts you in the moral lowgrounds
Again I will reiterate, I am not saying that you should not defend yourself, I am saying that you should only defend yourself in ways that are "necessary" (as is stated in law books everywhere).
I.e., do not defend yourself
As is not stated in law books everywhere
The "necessary" refers to the necessary use of force at all, not the scale of force involved m8
