I don’t want to ruin your idea, I think it’s kinda neat. But I think that you may be monkey pawing yourself.
A tremendous amount people have suffered so much, that I’d probably not want the experience in its current form. The horrors of the holocaust, unit 731, and a lot of wars springs to mind, from just the last century.
IDK how you could modify the question, but “no violent deaths” could be a starting point.
