Two sequential questions, prompted by the Notre Dame fire:
Is one obligated to wish that places of idol worship are consumed if they already are on fire? (I would think so, given e.g. OC 224:2)
If so, and if Christianity is considered idol worship, does the unique importance of Notre Dame make this apply less?
The Conference of European Rabbis and others sent supportive messages post facto, but that could have been a) mishum eiva and/or b) sympathy for people, but not the building itself.
