It's not our job to make the world safe for fundamentally unsafe people.
Are you suggesting we need government intervention or just saying "damn the consequences"?
We build cars, even though some alcoholics drive drunk. We could make cars safer for them by mandating a steering wheel lock with breathalazyer for every car, but we choose to not do that because it's expensive.
We have horror movies, even though some people really freak out from watching horror movies, to the point where they have to be placed in mental asylums for extended periods of time. We could outlaw horror movies to reduce the strain on these mentally troubled individuals, but we choose to not do that because horror movies are cool.
But it is, nearly every product, procedure, process is aimed at the lowest common denominator, it's the entire reasoning warning labels exist, or fail safe systems (like airbags) exist.
