Yes, unfortunately for as harsh as it sounds for anything at human-scale that inherently has some live-threatening risk, the ideal design is pretty much never 0-deaths. Anything I can think of: driving cars, sports, almost any job, etc. would need massive restrictions, to the point of those actions not making sense anymore, to reduce death risk to 0. So while sure, trying to reduce unnecessary risk, there's always a minimal amount of risk we are okay with.
