Do you think that people in healthy relationships should fear that outcome? Do you think people should become celibate because some percentages of relationships end up that way? The point is you are encouraging living in fear of low likelihood events.
The world is not perfect, crime and poverty exist, as do disease, many types of suffering, it's bad, but we don't need to be afraid and motivated by irrational fear.
There are lots of things that were statistically demonstrably worse in the past and also statistically miniscule in occurrence, but I think you would get righteously clobbered if you proposed defending their current rate of occurrence as acceptable. Lots of things.
There are outliers to that. I think medical research for something like a rare disease is a good one. High cost, and by some metrics, low payout, but worthy. I don't think this recent right wing paranoia about crime is a good example. Especially since the "tough on crime" policies that people want to enact in reaction to it do not work and have a tendency to incarcerate innocent and undeserving people as collateral damage.
One small anecdote, the first year or two I got here, I felt I was being sized up for muggings a couple times. Has not happened in a long time.
