People would still agonize. I live in Murica and have access to all the guns. Lots of people put guns to their head and cannot do it. The inherent violence of it, even though logically won't be known or felt, is terrifying to our lizard brain. No method is easy and no matter what you have you will find reasons to want something else to stall or deal with survival instinct. It's not natural to do this...it can be rational...but it's not natural. To expect other people to participate in this event, in this violent and traumatizing way especially, is madness.
You would pull the trigger eventually, I think, if you found it necessary to
In some ways a gunshot (particularly with a handgun I'd imagine as opposed to a shotgun) is a lot less traumatic than most other deaths
I'm not saying there wouldn't be any agonizing to it
That said, I only ever practiced with my rifle in my mouth, when I carted it off to go to do it, I got stopped
In my head I was saying that I would sit and wait somewhere and decide then whether I would do it, maybe I wouldn't have
That said I think the pressure of "it has to be right this moment or never" is unnecessary
There are ways to minimize involving other people
Doing it in the wilderness comes to mind, but there could ways to do it in a city
They have had automated car wash technology for a long time, I don't see why they couldn't have something similar for cleaning blood
@oopswronglife is right about this. Regardless of the method, the SI (survival instinct) and self-preservation part of our biology still gets in the way to interfere with our attempt. It is difficult to fully get rid of the SI (some debate whether it could be done or not), but just enough to give the person sufficient courage and conviction to follow through with the attempt.
Yeah but it takes more to get over the SI in some methods than others
Also if your aim is to avoid pain a handgun suicide seems best (other than maybe a good peaceful pill or whatever an approximation of that is, say Nembutal with an antiemetic, and I feel like there could probably be some way to neutralize the taste)
Much better than many other super physically painful methods
