The kids should not be removing some of their Dad's work. His struggles with alcoholism are well defined in the public and him describing his struggles could help another facing similar problems.
I wouldn’t say “should not”. That’s a complex issue and I wouldn’t say anyone is obligated to put painful moments of their personal lives on public display. Any family suffering from alcoholism has other examples to learn from, and they aren’t under any obligation to contribute another one if they’re uncomfortable doing so.
