Damn. I could never do it. Too coward. Gotta admit you have a point with the accident part but, wouldn't you ruin your "killer's" life?
Presumptuous to assume most innocent people have that level of guilty conscience. (Members of Sanctioned Suicide tend to operate on a much higher level than the average individual. We're excessively, inappropriately responsible, often groomed by psychopathic/sociopathic adults in our upbringings.)
Give it a little time. The abomination of driverless computer programmed vehicles is ascendant.
In point of fact, shit happens. Around 2003, a friend of my sister's was driving a bunch of friends of hers, and collided with one of a couple of idiot teenage boys who were drag racing towards them. She was badly injured (with some of her passengers), but recovered and went on with her life. There was never any question that the only criminals in that episode were the ones who died. (The next day, it was the top news story in northern New England.)
A few innocent "killers" with a predisposition to clinical anxiety might be traumatized for life, but if not substance impaired or otherwise breaking the law, then the "killer" is the victim, not the deceased self intoxicated criminal.
One Christmas season, a little old lady in front of me was killed when she was slammed down by a motorist on a busy downtown main street. She didn't bother to look, she just stepped right in front of a vehicle, and was not on a crosswalk. I have no idea how she managed to live that long being that reckless and stupid, but she did not deserve to belong in that driver's daily thoughts afterward.
Do you consider heroic getting euthanized so your organ can be donated to someone that really needs them? Because I wouldn't think twice doing it.
Now, I am NOT an organ donor, because I don't want to risk some worthless asshole like Bob Casey, Sr., Darth Cheney or Jeff Bezos getting to live by obtaining my organs.
My preference is to either hop in a volcano or the molten steel of a furnace the way Schwarzenegger's Terminator is lowered into one at the end of Judgement Day, so that no fucking pathologist or any worms or other organisms can feed on or otherwise benefit from my remains. (The world shit on me. This would be payback.)
