Suppose a building at a former concentration camp was designed, built, and used as a torture chamber.
The camp is now only a museum for those interested in the history.
But one night during a storm, the former torture building gets a broken window.
Question: Do you repair the window?

The building remains as a memorial to the victims of Nazi evil. To leave it in disrepair disrespects the victims. It could also invite further disrepair implying apathy.
